I was thinking, for myself; growing up as a SEGA kid, I'd far rather implement a GG/SMS emulator, heh.

I would say my interest is perked, though! I have a number of projects at the go currently that I think would prevent me from really dedicating all the effort I'd need to a project of that magnitude, but...it's also Z80, yeah? Mainly?

I did mostly Genesis ASM back in my ROM hacking days, which was 68k, with a Z80 sound chip.
