ok, this is frustrating but here's what I've got:
1. Gamelauncher, launched form horizontal desktop, goes vertical on its own, vertical games play vertical, everything's great.
2. Mamewah launched from horizontal desktop comes up horizontal (even using the vertical layout, its stretched funny though). Vertical games play in horizontal mode, shrunk to fit with black space on each side.
3. Mamewah launched from vertical desktop (rotated 90 degrees with nVidia software) launches vertically, looks great with vertical layout. BUT...games still don't work, I can hear sound, but black screen.
This is all with same mame config file, resolution set to auto. I tried in mamewah to add -rol, -ror, -autoror, -autorol, with no success, same black screen.
I'm sure there is some simple mame setting I am missing.
Any suggestions?
Thanks,
