>Anyway I hope someonr do the same with the Donkey Kong arcade ROM's. =P
Easy cheesy, actually. Just switch the sprite designs. What I haven't looked at yet is where the colors are handled (i.e. are pinks normally available for mario and reds for pauline).
It's such a simple graphic hack, actually it's surprising no one has done it yet for the arcade roms. (Which makes we wonder if the colors were the issue all along, I won't know til I look).
If I get time, I'll look at the process this in the next couple weeks. Sadly... isn't misfit done with updates? Can still play hacks, but now will require accepting the rom warning screen every time it boots.
