PC-JAMMA

The easiest way to use a PC in an arcade cabinet!

I designed PC-JAMMA to easily convert any arcade cabinet to run an emulator and still have the flexibility to swap game boards so I could still use my library of JAMMA games.

This single board converter uses all existing cabinet components and is JAMMA compatible. It converts the PC’s video signal to 15kHz RGB suitable for any standard arcade machine monitor. It connects cabinet controls as USB joysticks and as a USB keyboard. It amplifies and outputs the PC Audio to the JAMMA edge connector or stereo out plug.

How to use

Before we begin, I assume your cabinet is fully working!

Locate your old game board.

Unplug from the JAMMA harness and remove it from your cabinet.

Connect your PC’s video, audio and USB cables to PC-JAMMA.

Plug PC-JAMMA into your cabinets JAMMA Harness.

Put PC-JAMMA back where the old game board was located.

Turn on your cabinet and computer.

On the first run, Windows will need to download and install some drivers.

Once complete, Run your choice of emulator and start playing.

To run a standard JAMMA board instead of emulation is now as easy as swapping game boards.
