I recently received an email from HostedStuff.com (the host of Cemetech's news and forum) saying that because of rising costs, they will no longer be offering free hosting. I am going to temporarily return to the old, HTML-based system, but if anyone knows of a good, free remote CGI host please let me know.

	Doors CS 5 Breakthrough March 3, 2005 Discuss

	At long last, I have managed to make some progress on Doors CS for the TI-83+. I discovered what the bug was: all routines worked fine, but as I suspected, there was an underlying problem in what it was doing. It needed to swap the program to higher mem than Doors CS, not lower mem as it needs on the TI-83. I now need to devise a routine to swap it the other way around so that the calculator won't crash if prgmZDCS is in high memory. This should take a relatively short time, and I look forward to a projected release date in the next two weeks. The current beta (beta 3) can be found at the Doors CS Member Page.


	Further Doors CS v5.0 TI-83+ Progress February 28, 2005 Discuss

	So now I've tried three separate ways to swap a program from RAM into UserRAM ($9D95), and each works on VTI and the TI Flash Debugger, while crashing on a real TI-83+. I have finally discovered that I have been forgetting to decrement bc (program size) twice to account for the ASM token ($BB,$6D), so I hope that if I fix this and debug why the VAT is being corrupted, I can make it sucessfully not crash on the real calculator. I'll post more when I have tried this and have results (or lack thereof). In other news, The Cemetech program archives have passed 1,000 downloads since early December, and there are now 61 Cemetech members. My ticalc.org downloads are nearing 375,000.


	Doors CS 5 Bug Persists February 14, 2005 Discuss

	Since the last news article, I have been exhausting pretty much every possible bug that could be causing the Ion program crash. I thought that the swap routine might be the problem, so I completely rewrote it with bcalls in under 79 bytes, yet it still crashed in an identical fashion. The current evidence: Ion routines are not causing the crash Crash occurs with all ASM, Ion, and Doors CS ASM programs Therefore the swap routine used in all three of these program types must be at fault There are absolutely no coding errors in the routine - I have checked tens of times Thus there must be wrong with what it is doing, not how it is doing it Crash appears to occur Crash occurs before actual program code is reached Size, to, and from are all set correctly Here's the steps I'm planning to take as of now to determine the problem and how I'm going to solve it: Test with programs of different sizes to determine exact crash size It seems there is no exact size, so what is the range? What causes the change Determine exactly where in the loader the crash is occuring Is ROM 1.18 moving instead of copying ZDCS?? More to come.


	Doors CS v5.0: At The Verge of Completion Feburary 8, 2005 Discuss

	At some point last week, I believe around Wednesday, I realized that certain Ion (and Doors CS) programs crashed when run on the TI-83+ edition of Doors, yet only on a real TI-83+ running ROM 1.18. When tested in VTI with 1.12 and the TI Flash Debugger with 1.16, nothing of the sort happened. This led me to deduce that the problem could not be related to the archive, since the programs did not crash in the Flash Debugger. I began by trying to brainstorm what might be the problem. I looked through the Ion routines I was using, noticing a bug in the iRandom routine and fixing it. This cleared up a crash problem on the emulated calcs, but the crash on the real calc remained. I began to add modules into Doors CS to debug it. First I had it check and display the mem location from which programs were being copied. This showed that it was working correctly. I repeated the procedure with the program size, thinking perhaps it was creating programs of size 0 or infinity. Once again, the check showed that size was being registered correctly. In the meantime, I had a TI-83+ port of the Password Protection SE and DCS Pong v1.0, ironing out their bugs, and finding the rand error. After trying out a couple of sample programs and seeing that they only crashed when actually calling the library routines, I thought that perhaps the library table was being copied incorrectly. It seemed unlikely since it worked on the emulators, but I first inserted a debug segment in Doors CS that analyzed the lib table. It showed that the pointers were being set correctly. I then checked the first two bytes of each routine as it was pointed to; once again, it was correctly set. In desperation, I put the routine into a sample program, thinking that the swap was causing the crash. Still nothing; the routines gave exactly the correct value. So here I am now, stumped and frustrated. In other news, TI-Freak8x helped me in the archives project by uploading the screenshots for all of my programs to here from ticalc.org. I have also helped him with a neat project of his, a page in which he is trying to catalogue all of the TI calculator community sites on the Internet. You can check it out right here. This is Cemetech News Article #00097


	Archives Rebuilt (But...) February 1, 2005 Discuss

	Over the past month and a half I have gradually been rebuilding the Cemetech archives in a new, totally dynamic perl system. Of course, I had to learn Perl first to do that. So it is now completely done and operational. The bad news is that the file data isn't in the system yet; only the framework has been built. I also have put in the folder data, so the folders work, but there aren't any files in the folders yet. You can check out the current progress here. Keep checking back as files are added to the list; I'll post when it's complete. Doors CS is progressing smoothly; I found some bugs in the TI-83+/TI-84+ version that I am still working out, so the release should take place in about a week and a half. It will almost definitely be released by the end of February.


	Cemetech Archives Rebuild Progress January 29, 2005 Discuss

	I have been working hard on the new and improved Cemetech archives. While it is not yet complete, I have made substantial progress. Done so far: File page script File rating script (members only) File review script (members only) Still to complete: Folder view script Importing all file data If you would like to help with the last item, please email me at Kerm_Martian(a)yahoo[dot]com. If you would like to see a sample of what I have completed so far, check this out: Cemetech \| Programs \| Archives \| uLtra TOurnaMent II


	Doors CS SDK in Progress January 20, 2005 Discuss

	As part of the pending release of Doors CS v5.0, I am working to complete a full Software Developers' Kit to complement the shell. Currently I have completed two full wizards, one for ASM programs and one for BASIC programs, that will generate templates for programs, Shell Expansions (SEs), and Appended Library Extensions (ALEs). I am working on a PDF of the SDK document itself, and I will also create several supporting documents in addition to an include file (`doorscs.inc`) and a compilation program (`compile.bat`). You can see the progress that I have made so far on the Doors CS v5.0 SDK; you can also download the current Beta Testers' Edition release in the Projects \| Members \| Doors CS page.


	World Domination I Released January 17, 2005 Discuss

	World Domination I is a real-time strategy game for the TI-8x series of graphing calculators. It is based on games such as Risk; you battle the calculator AI for control of the world. Each player starts with several units to place around the map of the world, then take turns moving, attacking, and redeploying. If you or the calculator gains control of a continent, you get a number of bonus units. Defeat all enenmy troops to win the game. This game is fully graphical yet with a surprisingly small size, under 10KB. It is of course Doors CS v5.0 certified. You can download World Domination I at ticalc.org (it's at the bottom of the page). I'll put up a Cemetech file archive page soon.


	500 Downloads, 50 Members January 11, 2005 Discuss

	This past July of 2004, I inaugurated the Cemetech Forum, and with it a member system. The fiftieth Cemetech member has just signed up; I would like to point out the reasons for becoming a member: Access to special Member Pages Ability to download and test programs before they are available to the general public Receive special notices of important Cemetech news via email Post and discuss on the Cemetech Forum I look forward to many more users signing up. Also, In the middle of December I installed a new statistics system into the file server to keep track of downloads from the Cemetech archives. It has now received 512 downloads (incidentally 2⁹), the most popular file being World Domination I Beta with 32 downloads. The archives rebuild is still in progress, but temporarily paused as I deal with a problem at Tripod.


	Doors CS v5.0 Beta 1 (83, 83+, 83+SE, 84+, 84+SE) January 8, 2005 Discuss

	Doors CS v5.0 is now ready for the first beta release supporting all TI-83, TI-83+, and TI-84+ series calculators. Doors CS v5.0 Beta 1 can be downloaded by Cemetech members at the Doors CS Member Page. Download the file labeled 01/08/2005, and send the two .83p files to your 83 or .8xp files to your TI-83+/ TI-83+SE/ TI-84+/ TI-84+SE. Have fun! (Oh, just run ADCS). You can offer feedback, comments, and questions right here on the Cemetech Forum. If you are not yet a member, just click the "Register" link at left on any Cemetech page.


	Shell Expansions Working in Doors CS 83+ January 7, 2005 Discuss

	After wrestling with the source code of Doors CS v5.0 TI-83+, soon to be released, all day trying to solve a bug in the shell. I tried several different things, narrowing the problem down to a corruption of the temporary variables creating by Doors CS at 9872h. I finally discovered that for some reason the memory set to load SEs into was also 9872h, so I found a new place for them in APDram, 86ECh. I also cleared up a problem with ALEs (Appended Library Extensions). In addition, the manual is nearly done. I now need to check DCS assembly program running and write the SDK, and the final v5.0 release will be ready.


	Further Doors CS Progress January 6, 2005 Discuss

	Since I posted the last news article, I have been churning through the tasks I needed to complete. I found the major ROM bug, completed the new BASIC archive/unarchive routine, and fixed a slew of other bugs. I also made some minor improvements in the TI-83 version, so here's what I still need to do: Find ROM check routine [TI-83+] Debug pendfile arc/unarc [TI-83+] Complete manual [TI-83] [TI-83+] Complete SDK [TI-83] [TI-83+] Fix onload Off bug [TI-83] Test all 3 SE functions [TI-83+] Test DCS program w/ libcalls [TI-83+] Test DCS program w/ ALEs [TI-83+] Doublecheck inc to ALE [TI-83+] Test all arc/unarcs [TI-83+] More news shortly!


	Doors CS v5.0 Near Completion January 3, 2005 Discuss

	Happy New Year to the graphing calculator programming community! Over the eleven days of my Christmas break, I have made some definite progress on Doors CS v5.0. Although I am not yet projecting a final release date for the program, I have about a month of work remaining on the shell. I decided that I will be releasing four separate v5.0 editions, two for the TI-83 and two for the TI-83+/TI-84+ series. Each calculator will have a Standard Edition and a Professional Edition available (see logos below). The former allows only locking and unlocking of programs in the program modification tools, but is about 600 bytes smaller than the Pro version. The latter takes up more space, but offers locking and unlocking, copying, renaming, deleting, and archiving/unarchiving (if applicable) of programs. The most imposing obstacle at present is the ReadFromROM routine (I just fixed the other stumbling block). I will try to finish the program cores first, issue a Beta Testers' Edition, and then work on the manual and SDK as I receive feedback on the BTE. Here are the tasks I still need to complete and debug: Fix read from ROM bugs (3 routines) [TI-83+] Add DCS BASIC arc/unarc routine [TI-83+] Debug DCS BASIC arc/unarc routine[TI-83+] Complete properties menu [TI-83] [TI-83+] Restore properties menu to core [TI-83] [TI-83+] Add arc/unarc to properties menu [TI-83+] Add ROM/RAM check in Arc_Unarc [TI-83+] Find RAM for pendfile and ALEvectors [TI-83+] Store arc status of pendfile and rearc [TI-83+] Add arc/unarc to DCS, ASM, Ion [TI-83+] Eliminate AShell from VATFind [TI-83+] Check SE functions [TI-83+] Complete readme [TI-83] [TI-83+] Complete SDK [TI-83] [TI-83+] Fix unload Off bug [TI-83] Revert to old Off routine [TI-83] Fix battery status check[TI-83] Res textwrite,(iy+sgrFlags) before BASIc run[TI-83] Check ASMswap_TIOS[TI-83+] Make Professional and Standard versions [TI-83] [TI-83+] As you can see below, I also made the official logos today. You can comment on them and the project in general at this topic's forum thread. You can also view the Doors CS members' page at http://www.oocities.org/kermmartian/projects/members/doorscs.html (you must be logged in).


	350,000 Downloads December 21, 2004 Discuss

	That's right, since March 28, 2002, Kerm Martian and Cemetech have earned over 350,000 downloads from individuals downloading programs and files. To put that in perspective, I would have over $3,500 if I got a penny for every time someone downloaded a file. Also, the Cemetech archive rebuild project is going smoothly, and should be completed by the end of January. You can see the progress of the project right here. Also, I have once restarted heavy development of Doors CS v5.0 for the TI-83+. Once this is complete, I will be able to release v5.0 of both the 83 and 83+ versions.


	Forum Down December 15, 2004 Discuss

	Yesterday, the Cemetech Forum was unavailable due to a hosting error. The Forum is hosted by InvisionFree, and their Server 3 (s3) had a fatal disk error. They took the server offline to protect the data, and it has now been rescued and transfered to a new hard drive. The Forum appears to be fully operational once more; we apologize for any inconvenience this may have caused.


	Statistics Page Created December 10, 2004 Discuss

	Since ticalc.org recently disabled external linking to files and screenshots, I have rebuilt most of the Cemetech archives to be independent here. You can view the current program archives setup right here. I have also taught myself CGI (perl) in order to make the statistics page, available here. To date there have been 195 downloads (since the page went up about two weeks ago). I also plan to completely redo the current archives layout to be more dynamic and easier to edit; expect that part of the project to be done in about a month.


	World Domination I Beta Released November 30, 2004 Discuss

	I just released a late-beta version of World Domination I for the TI-83+, TI-84+, and TI-86 series calculators. World Domination is a Risk-type game in which you battle the calculator to gain control of the world. You each start with 5 or 40 troops, place them on the map, and take turns moving and attacking. The beta should be mostly bug free; if you find a bug, please post it on the Cemetech Forum. World Domination I: Download


	World Domination I In Progress November 16, 2004 Discuss

	For the past two weeks or so, I have been working on a new strategy game called World Domination I. Inspired when a classmate asked me if it was possible to program the classic board game Risk, I set out on this game. You and the calculator each start with forty military units. You must place them all over the world. When every unit has been placed, gameplay begins. You can advance, attack, and redeploy units. When you defeat all enemy units in a continent, you gain a number of bonus units (number depends on size of continent). The first player to destroy all of the other's units wins. More on this soon.


	New Poll Posted October 28, 2004 Discuss

	Thanks to the encouragement of several Cemetech members, I have posted a new poll. It asks what Cemetech project you are most interested, offering the following choices: Doors CS multiNet TICI 1.0 mobileTunes CAD3 DE Document DE Spreadsheet DE Presentation DE Draw DE CALCnet²


	mobileTunes Song Creator Bug Found October 27, 2004 Discuss

	As I was creating songs for mobileTunes using the online creator, I noticed that any note above the first octave (Octave 0) would be incorrectly transcribed and compiled. AFter much searching for possible problems such as missing brackets, commas, etc, I discovered that a single constant, in the equation for picking the note from the array, was off by 4. Once fixed, all songs compile correctly. Sorry for any inconvenience this may have caused.


	Graph 3D v4.0 Released October 14, 2004 Discuss

	Today Graph 3D v4.0 for the TI-83, TI-83+, TI-83+ Silver Edition, TI-84+, and TI-84+ Silver Edition. Graph3D v4.0 is a fully-integrated 3D graphing utility that can graph up to 10 simultaneous 3D equations. You can edit the window settings, zoom settings, and format from within the program. You can trace over any graph, and rotate and zoom graphs from the graphscreen. This complete recoding of the program optimizes the size and speed of the program, providing a cleaner and more intuitive interface. In addition, it is Doors CS v5.0 optimized and certified. You can download Graph 3D v4.0 at: Graph 3D v4.0


	CALCnet² Whitepaper Released October 7, 2004 Discuss

	Today I wrote and release a whitepaper about CALCnet², a networking protocol for graphing devices. It explains the bit- and byte-level protocols, as well as how it interacts with the TRILlIon protocol and can be used by other calculator programs. This will probably be developed as a Shell Extension for Doors CS once it has been released. You can download the whitepaper below: CALCnet² Whitepaper


	Ion Support in Doors CS v5.0 83+ Edition October 2, 2004 Discuss

	Ion support in the TI-83+ version of Doors CS is now operational. Any and all Ion programs can be run from the Doors CS desktop simply by clicking on them - Doors CS will recognize the format automatically. Note that because it is in the middle of the port, this version is not released to the public. Currently only the TI-83 version of v4.9.0 delta is available. You can learn more about Doors CS at the Doors CS members page (you must be signed into Cemetech).


	Cemetech Trademark Sound September 27, 2004 Discuss

	Using a variety of cool tools from CNet's download.com, I have made a MIDI of the Cemetech theme sound, then combined it with a computerized voice to produce this: Theme Sound Feel free to download and enjoy. Doors CS is also progressing well for the TI-83+. As many of you will note, I have made it work to some extent, and the basic features are working, if not well, then at lest partially. Stay tuned...


	Cemetech Now #22 September 26, 2004 Discuss

	In yet another milestone, Kerm Martian (at ticalc.org) is now in the 22 most downloaded authors of all time with 313,730 total downloads. In what may be a record for Cemetech, in the last 7 days, 5,971 downloads have occured as new calculator owners and returning users alike get programs to use for the school year. Cemetech projects are continuing to move along, especially the port of Doors CS to the TI-83+, which is progressing rapidly.


	Doors CS v5.0 83+ Development Begins September 18, 2004 Discuss

	Since Doors CS v5.0 for the TI-83 is just about done, I have begun to port it into TI-83+ format and change the necessary routines. Most important are the different VAT formats and the archive feature of the TI-83+. The complete list of tasks before porting is done: Change all ROM calls to bcall() Change SafeRAM equate references Edit VATFind for extra 3 bytes Add extra key for arc/unarc Create arc/unarc routines Get rid of TI-OS ASM run routine Change AShell routine to run TI-OS ASM Draw archived icon Delete SOS support Add TI-83+ Ion routine Add `ret` after Doors CS filetype ids ASM id from End\0000\End to AsmProg Pendfile host prog ROM page add Check RAM before unarc Check ROM before arc Remember unarc host to arc after pend done SmallWindow plotsscreen reference fix ZDCS to highest RAM after arc/unarc Main file launch system change DCS BASIC program arc/unarc Then after I do some beta-testing and update DoorsCS.inc, the readme.pdf, and the SDK.pdf, Doors CS v5.0 will be released.

Office DE Components in Long-Term Planning September 17, 2004 Discuss

As has been announced here, Document DE v5.0 is in progress, an ASM port of the popular BASIC office suite component. I have also begun to plan the interfaces of two of the other Office DE components, Presentation DE v5.0 and Draw DE v5.0. The fourth part of the suite is Spreadsheet DE, which I have not begun planning. I have also started to brainstorm a powerful CAD-3D program for Doors CS, tentatively called CAD³ DE v1.0. Simulated screenshots from the main windows of each program are below:

	Doors CS Delta News September 14, 2004 Discuss

	Doors CS v5.0 for the TI-83 is just about ready for release. Features that I have just finished and debugged include: Power-Off Function: Clicking the power icon in the lower left now turns off the calculator. ASU (Automatic Shut-Off): After about three minutes of inactivity at the desktop, the calculator will turn off. Just press [ON] to return to the desktop. I have also implemented a tentative native TI-OS assembly program executer. Currently, after quite a bit of debugging, you can run TI-OS (hex-formatted) ASM programs from Doors CS. However, the calculator will crash when the program quits. I think it's a stack error, and I'll see what I can do. Doors CS v5.0 for the TI-83+ is at long last started. I made a (long) list of to-do items, and designed the icon to indicate that a file is archived. I have also begun to devise a system that will archive/unarchive programs and their associated files. Look for more news from this department coming soon.


	Website Coordination Underway September 10, 2004 Discuss

	I have begun to work on coordinating the Cemetech website to be more uniform throughout. Firstly, I am making it that logging in on this page or from the message board will register the login in both places while at the same time making it possible to login without being brought to the message board. Secondly, I am making the sidebar and login feature be throughout the entire site with javascript, so that changes to a single template will change every Cemetech page except the forum. Also note that I added bookmark and print icons to the main pages when you are logged in for ease of use.


	Kerm Martian Reaches 300K Downloads September 5, 2004 Discuss

	On September 3^rd, 2004, Kerm Martian reached 300,000 downloads of his programs at ticalc.org and Cemetech.tk. This comes shortly after he has begun to fluctuate between spot 23 and 24 of all time. With the school rush on calculator programs beginning soon, I expect this number to steadily increase in the coming weeks. Doors CS is progressing smootly, and I am working on a full-length Cemetech trailer that will be published here when it is complete.


	Kerm Martian In Top 23 August 16, 2004 Discuss

	Kerm Martian recently reached the top 23 most popular calculator programmers of all time, passing Marcos Lopez and now behind Michael Vincent (see link). This comes with 296,000 downloads, or nearly three hundred thousand. Many Doors CS programs under development should soon be available, including Document DE v5.0 and Doors CS v5.0 for both the TI-83 and TI-83+.


	mobileTunes v1.0 Released August 11, 2004 Discuss

	Four days ago I uploaded mobileTunes v1.0 to ticalc.org. This program is a media player for Doors CS and TI-83 calculators, including support for these types of files: HQ MIDI files HQ MIDI files with album art Full motion videos Full motion videos with sound Slide shows Slide shows with sound The readme file includes a Javascript tool that helps you create ready-to-compile mobileTunes songs, and I look forward to the community releasing tons of (non-copywrited) songs soon.


	Doors CS v4.9.0 Released July 26, 2004 Discuss

	This is a nearly complete version of Doors CS v5.0, the next generation Doors CS shell. Now completely in assembly, it is now less than half of the size of the previously released version. This release contains support for Ion programs, AShell prorgrams, SOS programs with and without libraries, BASIC programs, TI-OS assembly programs, and Doors CS ASM and BASIC programs. It also contains support for Shell Expansions (SEs), similar to modules, and backgrounds. This version is mostly stable; only TI-OS assembly programs are unstable and some program editing tools are not present in this release. Mouse routines have been debounced and external hardware support has been perfected. Support for ALEs (Appended Library Extensions) has also been debugged. This is the last major release of the TI-83 Doors CS version before the final v5.0 release. I will now focus my energies on the TI-83+ version. If you have any questions, suggestions, or comments, feel free to post them at the forum.


	More Website Updates July 26, 2004 Discuss

	I have made several more updates to my website to make it more interactive. The login module at left now works perfectly to log you in to the entire Cemetech site; it will change when you are logged in. The new forum is now fully integrated into the rest of the site, with the same template and feel to it. So far there are eight users signed up: we need more! Document DE 5 is also progressing smoothly. All of the major routines are in place, but there are still some that need to be debugged. Doors CS for the TI-83 is coming steadily along, and the TI-83+ version has been started.


	New Cemetech Forum July 15, 2004 Discuss

	Thanks to the prodding of TI-Freak8x among others, I have added a brand new forum to the Cemetech website. The old one was quite clumsy and out-of-date, so I wanted something new. I wish it could be better integrated into the page, but oh well. Go and sign up, post comments, and explore! I will check it at least daily to answer any questions you have.

Document DE 5 Nearing Beta Release July 12, 2004 Discuss

Document DE 5, my upcoming word processor for Doors CS and TI-83 calculators, is nearing a public beta release. Most of the necessary routines are in place, although some are occasionally buggy. Today I finished the line break insertion/display as well as detection of a low memory situation to prevent memory corruption (see screenshots below). Still to do:

Make clicking the up/down arrows on scrollbar scroll

Fix the scrollbar erase

Fix the scrollbar draw routine

Fix insertion of text and redraw after

Make clicking in text place cursor

The great Cullen Logan, maker of the TI-86 PS/2 keyboard driver among other groundbreaking projects, is thinking of making the conversion program for Document DE 5 <--> .rtf files, which will be a great help to the project.


Adding line breaks	Low memory detected

Document DE 5: Styles, Backspace, More July 7, 2004 Discuss

Document DE 5 is running along smoothly; I sat bashing my head into the italics algorithm for two hours before I discovered that changing a sra a to rr a and removing another would fix it. Argh... But now bold, italic, and underline seem to work perfectly in display, and they can be set during realtime typing. Backspace kinda works; all of the routines are there, and they don't crash. However, although the previous letter partially clears, in memory the character remains for some reason. Also, backspacing or editing a file after closing it and opening it again seems to create a weird overwrite bug that I need to work on.

Hopefully the most major hurdles have been cleared by now, and the majority of the coding that I still need to do involves tedious line break, scrolling, and other routines that have to be exactly right to prevent a crash. I also am going to need a computer program that can convert .83p Document DE files in .txt or .rtf, so if anyone would be willing to do this, please contact me. As my Calculus teacher says, onward and upward!


Initial style bugs when I started	Working styles demonstrated


	Rudimentary Typing; DDE5 Character Set June 30, 2004 Discuss

	The super-beta of Document DE v5.0 now has a mostly complete character set and a rudimentary typing routine. Below (screenshot) you can see the characters that you can type with Document DE 5, in addition to the Tab and Carriage Return characters. In order to type this, there are three Alpha Modes: Uppercase, Lowercase, and Number/Symbol. The current mode is indicated by an `A`, `a`, or `1` in the upper right of the editing screen. You can also see the grayscale cursor in this screenshot. If you have any feature suggestions, please feel free to post them on the Message Board. Also note the brand-new cursors in use on this page!


	Document DE: File Creation Added June 28, 2004 Discuss

	It took a lot of fiddling with the _getk routines (note to self: need more _getk documentation for the community), but I got Document DE to create new files that associate automatically with Document DE 5. Using Doors CS v4.8.5 and up, just click a Document DE 5 file and it automatically opens itself in Document DE. I also created some proprietary cursor routines to change the cursor icon depending on the location onscreen. This seems pretty much done, although there is some smudging when the cursor hits an edge. Document DE 5 continues! Click here for an animated screenshot


	Document DE 5 in Production June 9, 2004 Discuss

	Since I just finished Pong v1.0, my major project (other than the ongoing Doors CS), I have decided to start intensive development on Document DE 5, the first assembly version of this erstwhile word processing program. I have built the basic framework so far, as per the specs I stated in an earlier article. Most of the interfae now works, and the bulk of the work that remains is the guts of the program. A gratuitous screenshot (note that the VTI skin is one that I am in the midst of making specifically for ease-of-use with Doors CS).


	Pong v1.0 and Super Saiya-jin Rage June 25, 2004 Discuss

	This week I have released two programs (both games) written for Doors CS, Pong v1.0 and Super Saiya-jin Rage. Pong v1.0 is your classic Pong game, but with a twist. There are powerups, including paddle shrink/grow, speed up/down, change balltype, and raygun. You play 21 rounds against the calculator AI, and the player with the higher score at the end wins. Your highest score is automatically recorded, and it is of course Doors CS 5 certified. You can download it here. The second game is Super Saiya-jin Rage, programmed by William White for the 68k line of TI calculators (TI-89, TI-89t, TI-92(+), V200). With his help I ported it to Doors CS for the TI-83, and although it seems to work fairly well, there are still some changes I would like to make. You can get Super Saiya-jin Rage here.


	PS/2 Mouse SE Released June 19, 2004 Discuss

	I have released a beta of a Shell Expansion for Doors CS v4.8.5 and higher that provides support for external TICI 1.0 hardware, in this case PS/2 mice. This is an improvement upon an earlier project and now works (hopefully) correctly. I would appreciate anyone who was willing to test it, and I will update the TICI 1.0 Hub version A plans at ticalc.org and Cemetech.tk soon.


	Pong, PS/2 Routines June 15, 2004 Discuss

	I did some routine updates and releases today. I released Pong v0.99 beta for Doors CS (it's only missing a readme). Scoring, high scores, raygun, powerups, etc are all complete and working. If you find any bugs, feel free to email me. You can find Pong v0.99 beta here The other thing I released today was a set of routines for communication between z80 calculators and PS/2 devices (i.e. keyboards and mice). This is something I have been working on for quite some time, and I will soon make these into SEs for Doors CS v5.0 that allow you to use a keyboard or mouse to control the shell. There are also some optimizations that I would still like to make on it.


	Kerm Martian in Top 25 Most Popular Authors Ever June 9, 2004 Discuss

	The milestone I have long awaited is now here! Kerm Martian (ticalc.org profile) is now one of the twenty-five most downloaded calculator programmers of all time, with over 280,000 downloads. The conjunction of this with the end of final exams works out nicely, and I look forward to a summer of project development and completion. In order to further these ends, I have made substantial progress in several areas. Doors CS is now nearly ready for a v4.8.4 delta release, and Pong v0.9 beta for Doors CS is now available. I have pending a Shell Expansion that will allow the use of the TI-Keyboard with a TI-83 running Doors CS (more about this soon). I have received several excellent suggestions and bug reports about Doors CS, so if you would like to make your input on the project known, please email me at Kerm_Martian(a)yahoo.com.


	Routine Archive Updates June 4, 2004 Discuss

	Due to the rapid rate of program release to ticalc.org (which people hav evarying opinions on), I have gotten a bit behind in updating the Cemetech file archives. Today I finished updating the Games section, and next I'll start in with the Graphics page. I have also released some Doors CS-themed ASM programs, most notably: mobileTunes v0.93 beta Pong v0.8 beta Program List Sorter (Shell Expansion) CopyBG v1.0 (Creates a Doors CS background) Also note that there is an out-of-control thread on the Message Board about possible super-features for Doors CS v5.0 TI-83+ edition. Update: Check out the brand-new Math page in the program archives! This is Cemetech news item #0056.


	mobileTunes v.93 Beta Released June 1, 2004 Discuss

	Today I released the first published version of mobileTunes, version 0.93 beta. This is roughly 50% of the size of v0.8 beta, optimized for Doors CS v4.8 and up, and mostly stable. There are still a few random crashes that occur, but I think that's Doors CS, not mobileTunes. I also released a sample song for it, Greensleeves (song format is now much more compact). Go download it, and I look forward to songs being released soon!

Pre-Summer Updates May 27, 2004 Discuss

Summer is approaching quickly; one more day of school before final exams, and I'll probably be too busy studying to post much for the next two weeks or so. However, over the summer I plan to get a ton of stuff done. Anomg these:

Doors CS v5.0 for the TI-83 completed

Doors CS v5.0 ported to the TI-83+

Document DE v5.0 created (all ASM)

Finish mobileTunes v1.0 (now Doors CS only)

Begin to make Doors CS 5+ into an app


Icon	Main interface
Document DE 5 Simulated screenshots


	Doors CS v4.8.0 delta Release Pending May 19, 2004 Discuss

	The 4.8.0 delta release of Doors CS is almost ready. I will release this version to the public on ticalc.org and here at www.cemetech.tk. This version will contain most of the features of the final v5.0 release, although I am [temporarily] taking out the program tools and ASM program running options. With v4.8.0 delta I will release Phoenix v2.1 DE (Doors CS Edition), Phantom v0.81 DE, and Password Tools, a self-installing Shell Expansion that provides the password protection feature previously in Doors CS v4.0. If you have any feedback or suggestions, feel free to post them on the message board. Also, I have pretty much decided to leave out Venus compatibility because very few programs are Venus-compiled and unavailable for Ion and/or Ashell.


	Doors CS v4.7.0 delta Updates May 12, 2004 Discuss

	Doors CS is now at v4.7 delta: most of the features of the final version have been implemented in some way, and most are stable. The major changes from v4.6.0 delta are as follow: Shell Expansion (SE) support Doors CS ALE (Appended Library Extension) support Debugged Doors CS ASM program running Program locking/unlocking There are still several things that need to be fixed/added: Scrolling up the desktop (down works) Decision whether to add Venus support (might add ~150 bytes to size) Some program instability when prgmADCS is in lower RAM than the program being run


	Quest II and Graph 3D v4.0 May 10, 2004 Discuss

	On Saturday, I uploaded Quest II, a Chip's Challenge-type of game. From the ticalc.org description: `This advanced puzzle-solving game combines the premise of games like Chips Challenge with mazes to provide hours of engrossing fun. The included level set includes 15 levels for you to slide, teleport, unlock, and bounce your way through. External levels are supported...` I am also updating Graph 3D v3.0 to the next major version. Major feature additions include: Simultaneous graphing of up to 9 three dimensional equations Much faster rotation of graphs The `Window`, `Zoom`, and `Trace` functions now fully functional Faster initial calculation of graph values. Graph resolution settings user-accessible


	Doors CS v4.6.5 delta Updates May 6, 2004 Discuss

	Doors CS is coming along smoothly; program deletion now works, libbed SOS programs are now bug-free, and Doors CS ALE (addended library extensions) are progressing rapidly. One particular feature that I just designed and created is the RAM Recovery Tool. If you have ever pressed [2nd][Quit] at a prompt in a BASIC program running under MirageOS, you'll know what I'm talking about. If the TI-OS interrupts Doors CS at any point with error messages, for example from BASIC programs, you would normally lose about 3KB of RAM. However, I have built a feature into the Doors CS loader that detects residual data in RAM and automatically deletes it, reclaiming the lost space and incorrect mem errors. Also, I have made a fast routine that deletes and recreates prgmADCS so that it stays in high usermem; however, when Doors CS quits, the TI-OS BASIC parser doesn't know where to continue; I need someone to explain how the parser (rom call _parseInp) remembers where the next instruction to be parsed is.


	Doors CS v4.6.0 delta May 4, 2004 Discuss

	As promised, here's an update on the status of Doors CS. Much progress has been made since the last update two weeks ago. Most program running now works, major features are all operational, stability is fairly good, and optimization is fairly good. Current file support is working for the following: BASIC programs AShell Programs Next-generation Doors CS ASM programs Doors CS v5.0+ BASIC programs SOS (without libs) programs SOS (with libs) programs All Ion programs Support is planned but not yet operational for the following: Venus ASM programs TI-OS assembly programs The desktop seems to work well, and scrolling is mostly operational: scrolling down is not a problem, and scrolling up does not cause a crash or memory loss, but some weird stuff does happen. Also, the delete/ rename/ copy/ (un)lock features still need work.


	Doors CS v4.4.0 delta April 20, 2004 Discuss

	As Doors CS is gradually built into Doors CS v5.0, features are added and bugs are searched out and zapped, updates will be posted here with screenshots and details. Currently it is at v4.4.0, with the latest published version at v4.1.0. The current v4.4.0 complete rebuilt is squished using a proprietary loader for faster execution and smaller size, with rudimentary program detection features and a full complement of other features. The program detection routine is very buggy, and program running routines have not yet been implemented. A variety of brand-new icons have been created representing the various types of programs, with automatic detection of programs with embedded icons. If you would like to suggest features, offer beta testing help, or point out errors, please post at the Cemetech Message Board. Second image is a theoretical image of what Doors CS v5.0 might look like with TICI 1.0 CSA (color screen adapter) support.


	Cemetech Syndicated at Ti-News.net April 20, 2004

	The rejuvenated Ti-News.net has launched a new service called Conglomerate that collects news from a variety of calculator sources and compiles them into a single page. You can view the Cemetech feed right here. Note to Ti-News.net visitors: you can discuss Cemetech news on the Cemetech Message Board.


	Doors CS Enters Delta Stage April 8, 2004

	Doors CS, the GUI and shell for the TI-83 and (soon) TI-83+ graphing calculators, has successfully reached v4.2.0 out of beta and will now enter the delta stage of development. The current v4.x.y versions have a BASIC core with an assembly kernal for non-BASIC accessible tasks; the delta status denotes that the current non-beta version will be available concurrently with beta versions of v5.0.0. Doors CS 5 will be completely in assembly with an optimized shell core that is half the size of a normal assembly program. Besides support for BASIC programs and uncompressed ASM programs, support will be fully stable for Ion programs (v1.6-compatible), compressed Asm programs, SOS programs, and AShell programs. The Doors CS proprietary ASM program format will be overhauled to take into account the new optimizations, with support for built-in library routines. If you have a suggestion, please post it on the message board! News items will be posted periodically as delta portions are completed; screenshots will come soon. This is Cemetech news item 046


	Second Year Anniversary March 29, 2004

	Yesterday, Sunday, March 28, 2004, was the second anniversary of the first program release by the Cemetech Calculator Division and Kerm Martian. Two years later, Kerm Martian is ranked 31 on the list of most downloaded authors of all time at ticalc.org with 254,286 downloads and 1 on the list of busiest authors with 275 files. Currently Cemetech is focusing on Doors CS and related projects: mobileTunes v1.0, Pong v1.0, and CALCnet² (see previous news article). Doors CS v4.1.0 for the TI-83 now has semi-Ion compatibility; that is, Ion programs now run correctly, but exiting causes a crash and programs are somewhat unstable. The major thing is that it works! Once that is perfected, I will tackle AShell and Venus. Update: Wow, over a quarter of a million downloads! I didn't even realize that when I posted the news article! This is Cemetech news item 045


	Doors CS v4.0.5 for the TI-83 March 20, 2004

	It's been two and a half months, so I decided to do a bit of updating on Doors CS v4.0. For this half-minor increment update, I increased the speed of the mouse cursor roughly 11x using direct input instead of a ROM call. In addition, I added 8-direction mouse movement: up, down, left, right, and four diagonals. I am also working on Ion and AShell compatibility and support for compressed programs. The TI=83+ version of Doors CS is also progressing nicely; keep your eyes out for that soon.


	mobileTunes v1.0, Pong, Updates March 12, 2004

	For those of you who are waiting with baited breath for mobileTunes v1.0, I have good news! I have several things still to do, but the bulk of the program is completed. I still need to: Fix the TI-83 memory leak problem Create a valid TI-83+ song template Fix the TI-83+ song load error and onload-crash error Finished the online song creator Take screenshots In addition, I am working on a Pong game for the TI-83/+. IT will have powerups, levels, etc. However, I am using the IonFastCopy routine; the screen seems to jump every once in a while. Otherwise it is progressing nicely.


	Program Consolidation March 5, 2004

	At the premier calculator site ticalc.org there was recently a news article about the admittedly horribly bloated archives. To do my part, I took a look at my page at ticalc.org and made the following consolidation changes: Half-done Sim City version consolidated into the latest Sim City 2004 release All RigView grayscale images deleted A file that I myself called useless was deleted (Cursor v1.0) Look for some additional changes soon.


	mobileTunes in Late Beta February 27, 2004

	My latest assembly project, mobileTunes, is now in late beta. This is an oncalc MIDI player with support for files up to 22K. The intuitive and fully graphical interface let you stop, pause, play, fast-forward, rewind, or quit in mid-song. The song name is displayed onscreen, and any file can be played simply by running the file. There is no need to open mobileTunes and then type in a name. Ideally you should use this with Doors CS v4.0, but I will provide a workaround so non-Doors CS users can take advantage of mobileTunes features. It would be done faster, but my USB GraphLink suddenly stopped working.


	uLtra TOurnaMent II Released February 17, 2004

	This is the sequel to the popular UnreaL TOurnaMent v1.0, the revolutionary all-3D first person shooter for the TI-83 and TI-83+/SE. This version contains seven new large, complex levels. The graphics engine has been rebuild from scratch and all of the previous bugs have been eliminated. Also, two-player link play has been added with a proprietary assembly program. This game runs on the ReaL 3D graphics engine, and includes incredible 3D wall and environment rendering. The game is completely graphical; even the menus are graphical. At a mere 4.5K without the multiplayer modules, this is one of the smallest 3D first person shooters out there. Each of the seven possible levels takes less than 1 kbyte. There is no annoying wait while the program loads levels or screens; after an initial install to set preferences, from starting the program to starting shooting people takes about 5 seconds. There are enemies to shoot that shoot back, and you must collect health and ammo. If you run out of health from being shot, you lose. Now Doors CS v4.0 optimized. You can download it here:


	Cookie Tools Added February 11, 2004

	A new feature has been added to Cemetech webpages, allowing you to see at a glance updates, programs, and news articles that have been added since your last visit. If this is your first visit, updates will be listed for all areas of the website. Currently it will alert you to new news articles and archive updates. Soon I will add new polls, new projects, and other aspects to this alert. Hope it makes navigating this site easier!


	Civilization Simulator I Released February 9, 2004

	In a landmark for Cemetech, Civilization Simulator I has been featured at ticalc.org. As they put it: Civilization Simulator I is a BASIC game for the 83/83+ by Kerm Martian. An ancient civilization is created and lives in 3-D, fully zoomable and scrollable. Your goal is to guide your fledging society through three ages, gathering food and building structures. Due to the nature of BASIC programs, gameplay is slow but the game does an excellent job with the graphics. You can download it for the TI-83 and TI-83+ right here.


	mobileTunes Project Undertaken January 24, 2004

	I decided that the best way to demonstrate Doors CS v4.0's associated program capabilities would be to create and release an assembly MIDI file player, consisting of a player and oncalc music creator. Any music file can be played simply by clicking on the file - Doors CS will automatically recognize that it is a mobileTunes filoe and open it with the appropriate viewer. You can see some preliminary screenshots below.


	Doors CS v4.0 Released January 8, 2004

	They said it couldn't be done. It's done. Doors CS v4.0 has been released, the first assembly version out of beta. All of the features are now fully operational and stable. Doors CS is an assembly language shell for the TI-83 that includes many advanced features for programmers, including icons for BASIC programs and icons and associated programs for assembly programs. It has a graphical user interface; the desktop and all sections of the shell can be navigated with the built-in mouse. Password protection, automatic low battery and low RAM detection, and even custom backgrounds are among the features in this edition. Doors CS v4.0 is available at http://www.ticalc.org/pub/83/asm/shells/doorscs83.zip.


	Archive Update Project January 7, 2004

	The Cemetech program archives have fallen hopelessly behind the actual rate of program completion and their appearance on TiCalc.org, so I have undertaken a project to update these pages. I have started with the Games page, and will soon begin the Education page. I have put all of the animated screenshots as separate Popup windows to speed the loading of the pages; non-animated screenshots are included on the page. I will post a news item when this project is completed. By the way, Doors CS v4.0 is on the brink of release!


	Merry Christmas and Happy New Year December 25, 2003

	It's nearly the end of the year, so I would like to wish the TI community a very merry Christmas and a happy, healthy 2004. Cemetech project updates: Doors CS v4.0 is within 1% of completion - the only bug left to fix is the shutdown bug (when the calculator is shut down from Doors CS, it turns on again immediately and only responds to the [ON] key). Age Of Empires II is progressing slowly but surely, and the great ps3d Engine (also a Cemetech project) is shaping up to give the game excellent realism.
