Did anyone ever find a hack that would get 9.2.2 to work on older Power Macs and thus sheepshaver? This would be quite useful for use with sheepshaver considering the NetBoot9 disk image freely available from Apple that contains a 9.2.2 system folder.

I played with it a bit and I can make the "incompatible macintosh" message go away if I swap these resources from an older Mac OS 9:

'boot' ID 3

'gusd' ID 1

After those resources are replaced, it shows the 9.2 startup screen and immediately gives an error type 102 and suggesting that I turn off extensions. When I do, it doesn't help.

I wanted to check here to see if it has already been done first before investing much time into this.
