If you want to give your retro game playing a properly retro look, this great mod uses the shell of an SNES system to house an emulator that plays games from over eight different systems.
Instructables user Vigo The Carpathian wanted to play retro games, with retro controllers, and have it all look authentic. To that end he gutted an SNES case, packed it with a microATX board, made some interesting mods (like a USB-to-SNES port adaption), and loaded it up with emulators to play games from the NES, Super NES, N64, Neo Geo, Gameboy Advance, Commodore 64, Sega Genesis, arcade systems and more. Check out the video above to see it in action and then hit up the link below to see how to build it.
