As for getting the ROM code, I'm already working on that. There's a hobby group that decapsulates chips and then writes emulators for the chips based on physically looking at them. (see www.visual6502.org) After they decapsulate and take electron-microscope photos of the chip, we'll be able to manually extract the ROM (which shouldn't be _too_ bad on these tiny little chips).


We just did it yesterday. I don't want to hijack this topic, so here I put my first experiences:

Wonderful, thanks for the heads-up! Smile One step closer to a full, commented listing of the assembler program...

Regarding my sound chip problem... the situation is stalled, does anyone have any new info or suggestion? A temperature reading of a known good game would be nice...
