How to get Zolferno's Ultimate trainer to work on nemexisOps
Really simple, all you have to do is rename BlackOps.exe to BlackOps.exe.bak
Duplicate BlackOps.dat so that you have one called blackops.dat and one called BlackOps - Copy.dat
Rename BlackOps.dat to Blackops.dat.bak and then finally rename BlackOps - Copy.dat to BlackOps.exe (with correct capitalization)
Run the game from the .exe that you have created and run the trainer once at the main menu.
