Youtube user MungoBBQ took an old Macintosh Classic and stuffed in a couple of controllers and a Raspberry Pi to make his own mini NES emulator.
The CRT had long since blown out, so he removed it and swapped in a modern LCD screen, then added NES – USB converters to get the controllers to work. A powered USB hub routes into the Pi, which runs the Emulation Station to get those classic 8 bit games.
The build is nifty, but he looks like he can use some help permanently attaching the LCD to the housing. Any ideas?
