A friend and I have recently begun playing BO2 Zombies / MP in custom games to relive the glory days.

I've found an old mod menu from the PS3 days and am having trouble figuring out how to get it to work for us.

The file tree is as follows:

• maps [folder]
  -- mp [folder]
  --- _ambientpackage.gsc
  --- _development_dvars.gsc

I remember having to use GSC Studio on PS3 to inject these files, but I don't want to do that with Plutonium as it is against the rules. How do I get these files to work properly?
