The IPAC is programmed with mame default configurations when the jumper is set to MAME. If you set the jumper to ALT, then run winipac you can configure each button to what you want it to be. You then shouldn't have to re-map the games. As for the no sound or wrong position of the screen, the IPAC is just a keyboard encoder and I can't see how it can have any effect on sound or image. Something else is wrong with that.
