"So where the hell do I get one?" I hear you ask. Mine came from a Tristar, aka "Super 8". This is a device
that allows one to play NES and Famicom games on their SNES. It plugs into the top, and has a pass-thru cable.
When the NES portion is in use, it bypasses the SNES' video and subsitutes the NES video instead. It is only using the SNES
for its joypads and power supply. If you happen across one of these and want to remove the chip (I used a heat gun), here
is the pinout:
