Sigh. Your response to the last thread I posted in was great, that was indeed the problem (no idea how I got ahold of MAME 0.65 in the first place, ha). So, here I am again; I now share the same problem as Nightlife. After seeing the improvements made to MAME, I decided to check out AdvanceMAME. It is working wonderfully all the way up to quitting, where GameEx now gives me the 20 Consecutive Errors after a "Memory Could Not Be Written" or "Memory Could Not Be Read" dialog box. I've tried resolutions of all kinds and combinations in all 3 domains (Desktop, GameEx and AdvanceMAME) with the same result. Video card is a GeForce2MX running Composite Out using the most recent drivers (I also updated GameEx to 4.04 today). I'm so close... : ) By the way, does anyone have any ideas on controlling Media Center with the gamepad as well? I suppose I could probably work it out with Joy2Key... Thanks again to all, Luke log.txt GameEx.ini.txt
