Hi,

I might need a bit of help here.

I compiled qemu with:

./configure --cross-prefix=x86_64-w64-mingw32- --target-list=ppc-softmmu --enable-gtk --enable-sdl --enable-debug

Then run gdb for Windows:

C:\qemu-debugging>gdb --args c:\qemu-master-msys2\qemu-system-ppc.exe -L c:\qemu-master-msys2\pc-bios -boot c -m 256 -M mac99,via=pmu -hda c:\Mac-disks\9.2.img
