Good afternoon, Just after some advice. I have a mister multisystem jamma on its way to me, which I am very excited about! I just wanted to check I am ready to plug it in when it arrives? I have checked my Jamma harness connector and some of the wires look like they are in different places to what a standard jamma pin layout is (see image). Also a couple of the voltages are a little bit off (see image) i didn’t realise the voltages were out as everything s in Ma to be working. At the moment I have a Neo geo one slot board plugged in and all working fine. The cabinet is a Lordsvale neo geo cab and I am pretty sure the cabs wiring is for a multi slot mvs board (I have a big red converter plugged in). Hope this all makes sense as I am still learning. Also if you would recommend getting a new power supply. Could you give me a good brand or shop to buy one from? Thank you. IMG_8684.jpeg
