Classic Mac PowerPC debugging

For quite a long time I was doing statical analysis for the old PowerPC Preferred Format Executable(PEF) program targeting the classic PPC MacOS (8.6-9.1) with IDA.

What I want to do now is to debug the application in the emulator(either sheepshaver or qemu, but the former is preferrable) from my host windows 10. How can I do this?

This is mostly uncharted territory, but possibly connecting to QEMU’s GDB stub will work.
