So I’m wanted to get into game reverse engineering. Specifically looking for memory addresses I can hook… I’ve seen loads of people do it with call of duty games where they use a PDB file that gives you the names of functions in IDA Pro… my question is how do I reverse a game when I don’t have the PDB file? I was wanting to reverse a halo game but I don’t have the PDB file. Where do I start?
