Based on https://github.com/dingusdev/dingusppc this series allows experimenting with binary ROM image from a G3 beige machine. It does not get very far though. Running with
-bios 78F57389.rom -d unimp,guest_errors -trace enable="pci*" | uniq -c I get the logs below and hangs reading the last reg. It seems to expect macio to be mapped at 0xf3000000 (also confirmed by comments in https://github.com/dingusdev/dingusppc/blob/master/devices/macio.h and some logs I've found on-line) but I don't see where it would set this up so maybe this needs to be mapped by default there?
