Can someone help me with debugging my G-Zero game.... PasteBin link below...

I should mention, I brought it over from Petit Computer, so there are obviously obsolete and outdated commands.

You'd be better off rebuilding the game by hand, really.

That's what I'm doing. But oh well, learning factors.

Debugging is hard, but it's going places... I'll put up a temporary program submission. My first one actually.
