Most of the programs referred to on my download page are rewrites of Manic Miner and Jet Set Willy, and include copyright code which was written by Matthew Smith for the long-since dissolved companies Bug-Byte and Software Projects.
Matthew Smith has said that he doesn't have a problem with people making modified versions of these games:
If you have a problem with this and you want to kill my joy in releasing such games on the Internet and everyone else's pleasure in playing them, then, after calculating the heartbreak you will cause in what's left of the community of Spectrum fans, let me know and - provided you can convince me that your authority with respect to the copyright is genuine - I will remove the offending material from my website, and you will be as the man who shot Bambi.
Please consider carefully the following factors before you make such a threat and thus condemn your soul to eternal damnation:
Equally, if you hold the copyright of Tolkien's estate and feel that I'm violating it by releasing Manic Miner: The Hobbit and Jet Set Willy: The Lord of The Rings, then you can tell me where to stick them, but you will bitterly disappoint all the Manic Miner and Jet Set Willy fans, and also fans of Tolkien computer games.
To prove that your authority with respect to the copyright is genuine, you must furnish me with the following information:
For further discussion of Spectrum-related copyright-issues, please see Copyrights and Distribution Permissions at World of Spectrum.
The rooms, graphics and other gubbins that I write myself in creating these games are my own copyright. However, being a nice reasonable person in such matters, I have no objection if you wish to redistribute them (free of charge) - in fact, I'd be honoured, and glad to see them exposed to a wider audience!
I also have no objection to you reusing any portion of my work here to create your own free games, providing you state that you have done so (including details of precisely what you have `stolen'), and please also have the courtesy to let me know, as I would be very interested in anything that follows from my work!
In either event, you must state that the (appropriate portion of the) code you release was written by me (either "Broadsoft" or "Andrew Broad") - failure to do so may be construed as plagiarism.
No portion of any Broadsoft game (or other program) is to be reused in any software that is sold for money. If it is, I will take legal action.
Copyright in text of the notes I release with my games also rests with me. The names and concepts of We Pretty, Goodnite Luddite and Kari Krišníková belong to me, so if you're thinking of writing any games, novels, TV adaptations &c. based on these, please discuss it with me first!
