But, the DOSBox patch included with the BMFREEW.ZIP only works with version DOSBox 0.63 (doh!). If you want to run under old versions of DOSBox (before 0.70), FreeDOS, DR-DOS, etc. you'll need to use this .BAT to create BIO.COM and run that .COM before every game session. (MS-DOS doesn't need it. "STACKS=9,256" in CONFIG.SYS should work around it. But feel free to try anyways.) Oh, and have fun! ;-) P.S. Kudos to Jim Norwood for his excellent work! -------------------------------------------------------------------- @echo off if exist %0.bat debug < %0.bat if not exist %0.bat debug < %0 goto end REM Tested w/ debug.exe from WinXP (MS-DOS 5?), Vista, & FreeDOS' debug.com REM REM BIO.COM patch written by Qbix for DOSBox : REM http://vogons.zetafleet.com/ REM viewtopic.php?t=11661&highlight=bio+rar REM REM Get BioMenace free (!) from here (needs 286 or better): REM http://www.3drealms.com/menace/ REM REM Run BIO.COM immediately before bmenace?.exe n bio.com rcx 72 a cs:100 mov dx,0125 mov ax,0900 int 21 mov ax,006F mov ds,ax mov dx,0014 mov ax,2501 int 21 inc al int 21 inc al int 21 int 21 inc al int 21 int 20 db "BIOMENACE Patch for DOSBox 0.61-0.65 loaded!",0a,0d db "Don't use it with other games!$" w q q :end --------------------------------------------------------------------
