Hi! So after probably year of taking a break and researching more, I'm finally setting up an arcade machine!
I bought a Taito Gameroom Classics bartop and it's pretty cool! It's wired with JAMMA, but the power supply I think is missing the -5 and 12 volt as there are no wires coming from the harness in those slots. It also has a small real arcade monitor and controls.
After the many roasts I got from my early posts, I spent many hours setting up a Pi 3 with RetroPie with the intention of putting this in the cabinet. However I am not sure what direction I should go. I love the new ArPiCade JAMMA adapter, but it requires -5 and 12 volts from the power supply. I could replace the power supply, but I'm not sure if the cabinet uses a standard power supply or not. My next option would be to use a JPAC and hook that up to the Pi, but I'm not sure if the JPAC does video/audio through the JAMMA harness.
My final option would be to take out the JAMMA stuff and replace them with Zero Delay encoders, and a GBS 8100 VGA to CGA adapter. However I don't know what to do about audio if I go that route, and I couldn't see any video cables from the monitor.
So if anybody could help me here that would be great! I'm still new to this stuff so be patient and thank you!
If anybody needs pictures let me know!
