I would like to buy a sigma from Kaiten Games, would I be able to use it for playing CPS2 games, I mean if i buy a CPS 2 board with games it will be just plug an play?, any suggestions?.
I depends on sigma model your using. It is pretty much plug and play, except you will have to plug in two harness [one for the kick buttons] instead of one.
If you're buying a new model Sigma AV7000, you're going to have to solder the other end of the kick harness to the custom Sigma harness for the 1P 4-5-6 and 2P 4-5-6 buttons, then connect the other end of the kick harness to the CPS2 board. Isnt as scary as it might seem.
