> Is this a known issue with the PPC core then?
The PPC core in current versions gives a full pass on PPCTorture's hundreds of thousands of opcode tests (the same validation is used by Supermodel, Dolphin, SheepShaver, and QEMU). So it's strongly unlikely CPU core bugs are the cause of any issues with the graphics; Konami graphics hardware frequently has very unusual functions and they're quite difficult to reverse-engineer.
