Hi I just bought an astro city cab, you know the Japanese candy cabs. I want to make it into a combo mame cab and to use it to play actual baords too. As far as I understood all I need is a jpac and an arcade vga card is that correct? The cab comes with 3 buttons per player and I wanna play street fighter on it so what would I need to do? The other issue is on the jpac web site it says to disconnect the power supply of the arcade cab, but then how would the marquee light and other things like the speakers work?
