ida_ppc_iop

Overview

IDA Pro plugin that implements disassembly of PlayStation2 PPC IOP AUX instructions.
Based on ida-emotionengine plugin by oct0xor: https://github.com/oct0xor/ida-emotionengine.

• Not hardware tested, based on disassembly of single file. Can be highly inaccurate.
• Very basic implementation.
• Missing few opcodes and dcr moves, will be added later.
• All names are custom.
• Tested only on single file (DECKARD emulator).
• Unknown opcodes show all 3 regs for now, while use only 1 or 2 of them. This is temporary hack (r0 is likely unused, unless code really point it is).
• This is hobby project, I'm not looking for any help with resolving missing opcodes or gathering info. Feel free to fork repo and do it on your own if you feel like it.
