PJ Features and Additional Information

Important: This adapter does not come with a raspberry Pi unit. You will need to provide your own.

Here’s a quick summary of PJ's features:

  • Inexpensive.
  • 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.

Currently, three distinct images are provided for this adapter. One, multi system image based on RetroPie, and 2 minimalist images with AdvanceMame, one of which is intended to behave like a single arcade PCB, and the one with a minimalist launcher.

Other linux images can be used as long as the provided drivers are installed and the system is configured to output video and sound through the proper interface.

For images, operation instructions, recommended setups, drivers, troubleshooting procedures, and more information on this adapter, please see the project page at:

  • Gradius III (SNES)

    Actual screenshot taken from an arcade cabinet running the PJ Adapter. This little thumbnail doesn't do it justice.

  • Wonderboy (MAME)

    What a great game. No pixel interpolation means sharp video without any scroll shimmer.

  • Sonic 2 (Genesis)

    A classic. This game looks absolutely stunning in RGB. The pic taken of the game in action on a CRT monitor, just doesn't come close.
