A micro arcade machine playing classic games using a Raspberry Pi running the Mame arcade emulator.
This projects turns a Raspberry Pi into a fully functional mame arcade machine complete with joystick, buttons and a battery pack. It even has a mini display at the top of the case to display the name of the game your are playing. The only thing it is missing is the slot to insert your 10p.
If you would like to build you own and are pretty handy with a soldering iron then full details can be found on the Sprites Mods website
