I found an arcade cabinet. The seller told me he cabled it as a Jamma standard. It has an old CRT monitor and a pcb with one game running on it. I would like to replace this board with a multigame one.
I read around that, at least the first ones, are chinese clones and might need some extra cable work. I believe someone referred them as "CHAMMA". I noticed these cartridge have a VGA output. I did not see anything like that in the cabinet. Is this for newer setup?
I would like to know if these boards are "plug and play" or not. If not, are there any alternatives?
