It also included a new audio extension, Sound Manager and CD/DVD driver and fixed the Y2K20 problem in the Date & Time control panel. at best.I was running Windows 98 with VPC 4 in OS 9.2.2 with a 466 MHz G3 Beige MT and it just wasnt worth it. It also included USB 1.4.2 in the Mac OS ROM file and fixed a sound issue experienced waking from 'sleep' mode.

It included FireWire 2.3.3 which fixed problems with certain DV camcorders and FireWire hard disks, and Open Transport 2.6.1 which fixed a bug that could be exploited by certain Denial of Service attacks. To be fair SheepShaver has some pretty extensive guides out there, and it's largely the same UI as the Basilisk II M68k Mac Emulator. Download os9exec - os9 emulator for free.
