I compiled a new SheepShaver build that solves the problem on my PowerBook G4. I posted it for others to try: <http://www.emaculation.com/forum/viewtopic.php?p=31574#31574> I built from CVS as it was today, with the exception of 5 files: To undo the "precise timer" patch (added 17-10-2009 and modified 21-10-2009) I used these files as they were in CVS on 16-08-2009: BasiliskII/src/Unix/sysdeps.h BasiliskII/src/Unix/timer_unix.cpp SheepShaver/src/timer.cpp SheepShaver/src/Unix/sysdeps.h To undo the "sdl-audio" patch (added 19-02-2009) I used this file as it was in CVS on 18-02-2009: BasiliskII/src/SDL/audio_sdl.cpp I think the precise timer patch caused the crash or freeze at startup on some (mainly PPC) machines. The sdl-audio patch appeared to cause degradation rather than improvement of audio performance. I already left it out of previous build.
