No problem. Got the javpac2 hooked up today.
Does anyone know if button 7 on a vewlix cab is available somehow? I think my cab came with it not wired. I haven’t opened the panel in a while.
What's a javpac? Do you have some kind of solution where the button and joystick wiring somehow splits off into 2 different I/O cards?
Do you also have 2 different video sources (PC, TTX2) routed to some sort of selection device?
If your cabinet's wired with the 2 Player Taito harness, I checked and it does indeed seem to only have terminals for 6 action buttons per player and the start buttons. Maybe the layout is just designed for options like either connecting the leftmost six buttons to a TTX2 or connecting the top 4 to an MVS.
Have you explored whether it's possible to just separately attach wires to each 7th button and run them through some kind of I/O board like an I-Pac or something? Maybe you could even somehow route the USB signal to both the PC and the TTX2.
For MVS games in particular, a simpler approach might be to somehow wire both the top-right button and the bottom-left button to the quick disconnects intended for the bottom-left button, IF that's safe. I suspect it is, but don't know much about electrical wiring, so I don't guarantee it's safe. It might be worth asking someone who makes wiring harnesses. If it's safe, the idea would be to wire both grounds to one terminal, and both other wires to the other terminal, then hook those into the harness quick disconnects for button 4.
The Neo-Geo arcade layout just has button 4 on the top-right instead of the bottom-left, so wiring both buttons as button 4 should achieve the same.
