I know the NES II loads on top, lacks A/V outputs, and the serial ports which were never used. It also has the crappy picture. I know the SNES lacks the eject button and has the RF Demodulator hookup instead of the RF output.
However, I was wondering a few things I never really thought about.
Did they change the NES II so that it would not work with the Game Genie? I don't know as I never purchased any Game Genie's before as I felt it was cheating (which it is). There was something else there that I faintly remember. Or was it that it doesn't allow those unlicensed carts that have the switch on them to work?
Same goes for the SNES remodel. Doesn't allow Game Genie or foreign adaptors? Not really sure of this. From the way it seems on the outside...this is a cool unit. Takes up less space, though I admittedly love the larger SNES and how it looks. Really elegant....too bad the remodeled NES didn't have picture problems...they match like fraternal twins...
