Another small thing i'd like to see in Mamewah is the addition of an "emergency exit" key combination or something along those lines. The reason this would be useful, is that MAMEWAH has frozen quite a number of times on me (only whilst setting up roms and emulators, not really when the cab is complete) and I am unable to multitask out of it to close the window.... yet windows is still running in the background. I found this wasn't a problem at all with XP, as I could control alt delete and close mamewah, but now that i've downgraded to 98SE, I have to restart each time.
For example, if you push Alt + Q (doesn't really have to be cab friendly, as if it's this situation you may as well pull out a keyboard anyway) it would do a emergency exit of mamewah.
Nothing serious, just a small little addition that would make setting up the software easier.
