I am interested in developing a PowerPC emulator for my own learning purposes. I've found a fair amount of resources about programming in PowerPC assembly, but after quite some time looking, I haven't been able to find an instruction/opcode mapping table anywhere yet. Of course, I need the opcodes to be able to write an emulator. Where can I find one?
Here's one: http://pds.twi.tudelft.nl/vakken/in101/labcourse/instruction-set/
