i wonder if SNES if possible?
Probably, there is already a snes emulator for Arm processors, it runs pretty good on 6800s. I'm guessing the above NES emulator was ported from the arm ppc ver. Allthough, NES emulation has been out since like 95-96, so maybe it was done from scratch. I remember when SNES96 finnally got sound on my Pentium I 133Mhz, it was the greatest day of my life, except for today
