After visiting the TKKR Lab and their famous Arcade Gaming Box, i often thaugt about building a smaller one.

So here are some ideas for the hard- and software:

• Raspberry PI running an emulator like Mame
• a small TFT or Touchscreen
• disassmble this one USB Joystick an use the USB Controller alternatively 32 Button Interface
• some buttons like this one joystick
• something like a Coin Comparator would be nice too
