Looks great. 8k FRAM, 128k sram, 32megabit rom, custom mapper, bi-region support (make a game/demo boot on both region systems). The mapper is custom and not compatible with SF2. The rom layout is also just the lower 512k, so it wouldn't run an rom larger than 4megabit without being specifically written for the mapper interface. I.e. it's for new dev, not playing commercial roms on a flash card.
