I set up my new PC last night, and for some reason when I launched several games in Mame32 they came up rotated on my standard Dell monitor. I mucked about with the settings and I could fix a couple of them but not all of them.
Let me clarify, MOST games played fine. I had trouble with Frogger, one of the Namco Classics, Gals' Pinball...maybe one other.
I haven't tried this yet, but I suspect the problem might be that I have the resolution set too high?
Any advice appreciated.
