Will there be great enthusiasts of Amazing Quest who will want to work with it as developers? I’m not holding my breath, but I always participate in the projects of the creative commons and of free software, because I believe in them.
Amazing Quest is a real Commodore 64 BASIC program, not “fake-bit.” While I have made all the documentation available in an accessible way (using ALT text), I could not see how to make the game itself work accessibly while running in an in-browser emulator. For me, it was essential that the game be a real C64 game. So, the best I can do is to allow anyone else to develop accessible versions in other programming languages, if anyone wishes to do so.
For those who wish to port or translate the game, I am offering all the game materials (index.html and the documentation pages intro.html and guide.html, as well as the core BASIC code) under the Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0) license. As that page explains, this also allows you to expand, remix, and otherwise change things about the game. If you choose to redistribute what you did, you just need to give appropriate credit, indicate if changes were made, and release what you did under the same license.
I am also offering just the BASIC code of the game under an even more permissive license, an all-permissive license, which follows:
