is back+black the only combo you can use in game or are there other ones? I like that fact that you can't use save states, helps the game seem more realistic like I used to play them. I would just recommend a tab like GUI to switch between systems because to me its just weird to have my emulated console roms integrated with my arcade roms. Oh and a synopsis for each game like the madmab editions have but include arcade roms as well, I think that would be my most requested new feature.
