New to this - using J-PAC but buttons 3 and 4 are wired to kick harness??
dailygeek:
both players have buttons 5 and 6 as well so I'll probably wire 4,5 and six into the jpac and 3s on jamma as there isnt a terminal for 3 on the j-pac.
Do I need to solder to the jamma harness? Never soldered before!
Malenko:
The JPAC has screw terminals for switches 4,5,6,7, and 8 for both player one and two (and speaker +, - and ground)
so if you cant splice into the JAMMA harness then you can do a simple remapping in MAME and use the screw terminals . For example you can screw in the wires for button 3 into screw terminal 8, then remap button 8 to 3 in mame or whatever emulator you're using.
