There are known issues with the PowerPC emulation:
Prep has been broken long ago by PCI patches. One has reported the exact
patch that did break it but the ones who did that patch never felt like
he has to take care of making it work properly and I did not have time
or motivation to search more.
As far as I know, the mac99 target is the one known to run but
unfortunately some patches have broken the IDE CDROM support during this
summer. I will have to find a work-around in the firmware as I also
noticed that it was bugged when ran on real hardware. For now, I do all
my test booting on hard drive disk images or flash images (for PowerPC
405). I'm currently working on the core emulation but I will come back
to do some fixes in the hw part / firmware part soon.
