Quote from KaPH33n: “this should get you started: wiki.arcadeotaku.com/w/Sega_Blast_City_Wiring_Guide wiki.arcadeotaku.com/w/Kick_Ha…2FCPS3_-_2_Player_Harness you essentially just make a ground wire with several connectors on it to hook up to the extra buttons. then run one signal wire to each button. inside the cab you have to do the reverse pinout to cps2 connector. ” Sorry for being so indecisive, but I think I'll just buy one from YAJ. Do you have a link to his page? I couldn't find his prof…
Quote from KaPH33n: “yaj has used ones sometimes. you can just make it yourself for less than they charge to buy one... but your time is worth something too. best bet is to get a used panel that includes all of the harnesses. Don't forget though, if you use the aux button input in the control panel, you need a matching output one for down inside the cab next to the JAMMA connector. so you will probably have to build that regardless. maybe Lemony or someone sells an astro to cps2 already wired up…
Windygaming offers it, but it's out of stock and ebay only has one from Canada for about $40. Any other place I could it from? Maybe building one myself?
