CHAMMA to JAMMA Adapter
Couldn't load pickup availability
Allows you to use your Pandora Box, Game Elf, or similar multi-game boards with the CHAMMA pinout, in a JAMMA 6 button cabinet.
CHAMMA (Chinese JAMMA) is a 6 button per player JAMMA pinout variant that has buttons 5 and 6 on pins 26, 27, 54, 55 of the 56 pin edge connector.
This is incompatible with the JAMMA standard due to pins 27 and 55 being wired to the ground, and pin 26 and 55 typically being unused. All 6 button JAMMA cabinets must therefore supply an additional wire harness for buttons 4-6 to remain fully compatible with the JAMMA standard.
This adapter can be used to connect multi game boards that use the CHAMMA standard to the existing wiring in the most popular 6 buttons JAMMA cabinets. Button 4-6 harness headers are included for cabinets such as Street Fighter 2, Mortal Kombat 1, Mortal Kombat 2+, Killer Instinct and Capcom's CPS-2 cabinets.
Game Compatibility
Game Compatibility
The adapter has been tested with a Game Elf and Pandora game boards.
Some compromises had to be made in order to allow for the best possible game experience in 5 or 6 button Mortal Kombat cabinets. In 5 button Mortal Kombat cabinets, CHAMMA button 5 (SF2 medium kick) is unavailable and CHAMMA button 6 is mapped to cabinet’s low kick. In Mortal Kombat 6 button cabinets with a run button, the run button is mapped to CHAMMA button 5. This configuration is the closest to a Street Fighter 2 button layout.
However, on Pandora Box boards, Mortal Kombat (the only MK game) uses button 5 as low kick and button 6 as block, so the game will not have the correct button layout in any of the cabinets used. Please keep this in mind if playing a choppy version of MK1 is important to you. The newest multi game boards have a button remapping feature which overcome this issue.
As always, before ordering and connecting your board, please check and verify the pinout information below.
