God of War III [BCES00510]

At least is not fake. I don't know how to verify what broke the game

You perform a so called binary search.

You know that it worked with that 8 months old build, but that it doesn't work with the current one. So you try one that is 4 months old. If it doesn't work you try a 6 months old build, if it does work you try a 2 months old build. And so on. Continue until you find the exact build that broke the game. As you halve the number of possibilities in each step you are guaranteed to find the bad version after just a few tries.

There are proper ways to do this with git but really you can just start downloading from https://ci.appveyor.com/project/rpcs3/rpcs3/history

Have fun
