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

PC-JAMMA Rev 3.00 is here!
Bringing the same great functionality as the previous version—at the same retail price!
Designed to effortlessly integrate any arcade cabinet with an emulator, PC-JAMMA lets you swap game boards anytime, so you can still enjoy your JAMMA PCB collection.
This JAMMA-compatible single-board converter works with all existing arcade cabinet components. It transforms your PC’s video signal into 15kHz RGB, perfect for standard arcade monitors, and converts cabinet controls into USB joysticks and a USB keyboard for seamless gameplay.
PC-JAMMA also features a CPS2 compatible kick harness for six-button games, which can be configured for 4-player (4-button) mode. In two-player mode, button 4 is available on both the kick harness and JAMMA edge connector ensuring full Neo Geo cabinet compatibility.
For powerful sound, the onboard stereo amplifier drives the cabinet’s speakers via the JAMMA edge connector or the stereo out plug.
