I tried for hours to find a concrete answer to this.
But most people with this issue are on Macintoshes and shit so yeah.
I'm on windows 11, rig is as follows:
AMD Ryzen Radeon 3 3200G, 8G Ram and a NViDiA 1650S.
Now the issue at hand..
The ones I've got that work (with a bit of effort):
Sorbet Leopard R15 (you need access to a Mac to convert the DMG to an uncompressed disk image which is then immediately bootable)
Leopard 10.5.8 PPC Only Restore Image v1.dmg (MD5 starts 6307) (again, you need access to a Mac to convert the DMG to an uncompressed disk image)
Mac OS X 10.5.6 DVD-DL.dmg (it's a compressed dmg, so you may need to convert it to iso before you can use it)
QEMU can use dmg files, but they need to be uncompressed. Sorbet Leopard is a great one to use in QEMU because it's a pre-installed disk image -- you just need it uncompressed.
