I am running Cedega 5.2.3 , running ASE through Crossover -- Cedega runs Quake 3 / 4 well. I don't have any other games to test. XQF browser can be configured to play games from Cedega , I just like the way ASE handles mods.
Has anyone tried OSX x86 version through QEmu? I cannot seem to get it past the initial boot, kernel panic. The error seems to be that QEmu doesn't do the SSE instruction properly. All nixes open fine, XP Pro install, opens fine. I had 4 Linux distros , XP Pro install, and OSX running at the same time.
