I've had some annoying problems the past few weeks in Mame with my IPAC. I have two players, each with 6 buttons. Through MAME itself, I have no issues with ghosting. Even through Game Ex I don't seem to have any problems until extreme button mashing/two player action ensues. Once the ghosting occurs, the game becomes unplayable. It will go away if you leave the controls alone for a few seconds, but it's very annoying and it will come back as well. I'm using mame 1.09 and the most current version of Game Ex. I've searched the forums/FAQ, found something about a pagefile? To no avail, it did not work. My cabinet has 512MB RAM, a 9600SE, and an Athlon XP 2100+ processor. To my knowledge, this should be plenty of power to run the MAME games. Any input/ideas would be much appreciated.
