I was tempted by a GB emulator too, so I'll be following this with interest! >From what I remember, the CPU side didn't seem too bad, with RST replacements for special opcodes - with a trailing code if there's room, or with an extra lookup for single-opcode replacements where there wasn't room. The display seemed like the biggest challenge, with quite a lot of sprite and scrolling flexibility on the original device. I guess I'll have to wait and see how you tackle that, and what framerate it ends up with... :-) Si
