I didn’t find out about Mark’s version until I was halfway finished my version. I did this as a learning experience so it’s all good, I also supplied all my source code so if someone else wants to learn how to do this for similar hardware or just to learn from they can look through my code and maybe use the ‘C’ program to help translate 8080 or Z80 assembly to 6809 for other games.
Also someone can also use the source code to rotate the graphics so they can play it on a real CoCo
I was thinking that with a 6502 to 6809 translation that someone could port the Apple II or Pet to the CoCo 3. Of course you couldn’t play any machine language games but you probably could run basic games made for those systems on the CoCo translated version. I think that would be cool to see…
