Just use a kick harness, no such thing as standard 6 button JAMMA as JAMMA is only 3 buttons. If you are looking for an adapter to just plug and play your current kick harness, you can probably mod an Atlas to do it.
yes, that's it, so my idea would be a adapter to hook it up to any Jamma cab.
Changes need to be made;
- Add a volume pot to 25, 26, d
- Make the select button 24, b optional with a Jumper for example
- connect the Y and X button from CN2 to Jamma button 3/4
- connect the L and R button from CN2 to kickharness button 5/6
- 4 pin breakout for stereo out similar to you MVS adapter
Button remap-able with jumpers would be a big plus
Makes sense?
I can also make some pics of the board if you like
And with standard 6 button I actually mean Jamma + kick
I already have a kind of functional home made adapter, but looking for a tidied up solution.
I have my Nintendo Super System configured to mono now (done via jumpers on the motherboard), but would be cool to have it in stereo directly to my amp!
