I was wondering if anyone can advise the 'best' way to play these games on a G4 Cube (450MHz) running 10.4 Tiger. I just tried installing them using an early version of Boxer, but they were so slow as to be unplayable. I managed to find a port of Quake II that works on Tiger natively, but am struggling to find anything for Doom or the original Quake (everything commercial seems to be for Mac Classic rather than OSX.)
