The GOG.com version works perfectly in CX11 on my MacBook Air (GeForce 320M, 10.6.8), when run using the -no3d and -doublebuffer flags using the "Run Command..." menu option, as outlined before.
The only problem is applying the Widescreen patch. It's a .bat file, and I can't seem to be able to run .bat files using "wineconsole cmd"; it just keeps telling me "File Not Found" even though I'm typing in the right path.
