Have you ever been in the situation where you wanted to play those nostalgiac Super Nintendo games with your friends while on a 200 mile long trek through the rainforests of Madagascar? Probably not, but if the situation ever arises you could use this sweet emulation machine that you are about to learn to build. The emulation machine runs off of a Raspberry Pi running Retropie, this allows it to support various emulators such as NES, SNES, Gameboy, Gameboy Color, Gameboy Advance, Sega Genesis, Neo Geo, MAME, PlayStation One and can even emulate an Apple II.
WARNING: Neither Instructables nor I condone illegal activities. As long as you own a hard copy of the game, you may use a digital backup within your emulation console for personal use. http://www.copyright.gov/help/faq/faq-digital.html
