Received this awesome RGB Scart to JAMMA adapter today from Australia. A couple of days ago I also got a pair of Akihabarashop‘s P360 so tonight I finished wiring it (no soldering nor crimping needed) them up like this:
The RGB to Scart adapter picture have a nifty ribbon cable that you can move from the screw connector board (where I hooked up the P360, green screw connectors) to the one on the far right with the JAMMA controls passthrough board. I plan on using this setup for my low res only cabinet. I tried some quick PS2 hookup just to see the picture quality. It is brilliant!
