I installed emulamer's GAPI driver, and that seems fine. Graphics look good and, on some games, are very fast. Sound is iffy, at best. I'm running v9.50.

The main problem I'm having is landscape mode. If I switch the screen into landscape using control panel, it doesn't make a difference to mame. If I use the rotate screen left option in mame, it turns the screen upside down. If I use rotate screen right, the screen remains in normal portrait layout.

Any ideas?
