To quote: Hey there PSX, here is a much better tool of a tool that I released for Black Ops 1 real time modding way back when.
The tool requires you to have a DEX ps3, the tools works by rtm(real time modding), it edits the memory of the game. You don't need any .dlls, the only thing you got to make sure you have is Net Framework 4.5.

I finally got it working. A lot of manually patching finally got it working. The original files above aren't the right files that was the first problem I had. Then after the file was patched with this it had to be resigned for 4.21CFW then it worked.
