@Jackson: Not if you originally had Petit Computer in the past.
@MYCRAFT: Tennis wasn't on PTC... Space invaders was though! Do you think it could make BGREAD and CHRREAD working commands?
I have a game that I want to port, it's called G-Zero.
Not that anyone knows of, you could try making one yourself just to see it crumble right in front of you, all because you weren't able to get that one thing to do a thing to start doing things.
Could you at least release a version that doesn't have any of the sprites? Or at least just the code? I want to look at the source code and use it as a reference.
