So I was reviewing old stumble upon pages and came across one that I liked and thought I would share. I read about it at Technabob (blog). They say that it is the work of a french modder named Kotomi (blog as well). He took all of the innards of the origional NES and somehow squeezed them into an origional Super Mario Brothers NES cartridge, includeing both controller ports, audio/video ports, and on/off and reset switch. It is truely amazing. I would definately want one.
