Raspberry Pi to JAMMA Adapter

The Raspberry Pi to JAMMA  is an adapter that will allow your Raspberry Pi to connect to a JAMMA compatible arcade cabinet for an unbeatable multi-game emulation experience.

Here’s a quick summary of features:

  • Inexpensive – cost still TBD.
  • Works on all Pi devices with a 40 pin header (no Pi 1 A models unfortunately)
  • Low latency control hardware – joystick and button status updates each frame.
  • Straight, one step digital to analog, video and sound conversion for a clean picture and sound.
  • Native video resolution – no scaling or shimmering artifacts with standard res games.
  • Zero latency video – one step digital to analog conversion, no scaler buffering required. 
  • Power monitoring and reporting.
  • Auto shutdown on brownout (with a super capacitor bank) will not chew up your SD card. Just turn off your arcade machine and walk away.
  • Images for major Retropie releases will be provided.
  • Opensource drivers and configuration for more customization.
  • Plugs into JAMMA with SF2 kick harness support.
  • All IO done through GPIO header. Nice and clean with no messy wires.
  • Old skool, through hole design with IC sockets for easy repair and troubleshooting.

Beta testing is now completed, and will be available very, very soon. To purchase PJ, and help support my projects, please visit my eBay page here
