Well, I'm running Win 98 and I haven't touched MAME32 :)(posted 9304 days ago)So far I've been able to run most games in a default DOS box, and everything by booting to DOS - there should be an option in your shutdown menu. You can also try picking up TWEAKUI to allow your computer to start in DOS first instead of windows.
In case anyone cares, my 4th of July trip was a disaster and I'm very heavily congested and very weak right now.
