Put this together today. It's a Pi zero, running retro pie. Its got a modified B&W LCD screen (to run on 5v instead of 12v) mounted portrait with custom margins set and connected via composite. it uses GPIO stereo audio using the 4 caps, 4 resistors method to voltage drop and filter the digital PWM from the pi and GPIO controls soldered directly onto the pins. I then had to push that through a PCB stereo amp which brought it up to acceptable sound levels.

Powered from a pound shop USB battery bank. The donor mini arcade itself was from a local gadget shop and was about £20. The 200 or so included games were shockingly bad, hence this project!

Plays most mame games fine, NES, Megadrive etc. all seem OK. There's not enough processing power in the Pi Zero to handle things like N64, PSX or Amiga properly but I have larger cabinets and systems for that sort of things so this just needed to play mame to be honest.
