for my mame cab, i want to have an xarcade as the main arcade stick controller, but since i will also be emulating snes and gen, i want to have controllers hooked up too. the xarcade has predetermined controls (example: v=a button), but so does the adapter i have for the ps2 controller. what do i do if they don't match up, and i want to beable to switch between the two for gaming. does anyone know of usb-ps2 adapters that allow you to customize your controls.
