A rogue AI has infiltrated a game server's custom VM run on PPC and its code is now traversing the user base. The developers have decompiled and given the current executing script the memory it was accessing at the time and opcode documentation. You are tasked with investigating the nature of this threat.
You were given three files:
opcodes.md with an incomplete description of opcodesctf.xsa with assembly (as in: text) for some architecture
