Hi, I have my Ipac4 and optipac working well with the exception of the R button on the optipac. It appears to be wired fine, the left button works just like the left mouse button in windows. My trackball works just like a mouse also, but the right button appears to do nothing.
I'm using the serial port, player 1 config only. I do have 2 buttons hooked up to both L and R buttons.
Any help greatly appreciated. I have no clue on what else to do.
