Not that I know of, though I did have to end up going to a regular version of MAME32Plus because WolfMAME didn't support multiple BIOS. (LAME!)
I have force aspect ratio checked, but even if I uncheck it, it doesn't affect anything, other than that - the version of MAME i have doesn't really have any options for changing things past running in a window and setting everything to auto.
I know it's something having to do with my ArcadeVGARes.exe tool, I dont know why its not working.
