This is a 6GB virtual hard drive with Mac OS X 10.2 fully installed
and set-up. The Classic environment has not been set up. I tried to
install it, but to no avail.

I've placed Firefox 1.5.0.7 into the Applications folder, though upon
initial testing it doesn't work properly.

The emulated machine is a Power Mac G4 with 1GB of RAM, though you can
change it to a G3, and/or alter the amount of installed RAM, in
10.2boot.bat.

This install was set up using the United Kingdom locale, and the
language is set to US English.
THE ROOT PASSWORD IS "Fox32".

Performance is pretty good, despite QEMU not supporting GPU
acceleration. Tested on an AMD Ryzen 5 3500U.

I'm uploading this here as I personally could not find any such pre-
made QEMU systems, and thought it might be helpful for others looking
to get into PowerPC Mac OS X emulation.
You will also need to download and extract the zipped QEMU-Win64
folder, also attached here.
This is for Windows hosts only, and will not work if you're planning
to run this on a Mac host, you will have to find and download the Mac
version of QEMU (with PowerPC support) yourself.

The 10.2boot.bat script was made for Windows, but might work on
macOS/OS X hosts. Compatibility with Mac hosts is not guaranteed.
