PAKPatch is a plugin which alters Rockstar Games vision of loading configuration files.
Manhunt uses ManHunt.pak (only on PC) to load all configuration data, this is a binary file with simple XOR encryption. Extracting this file will not make the game load raw files, instead, they will be loaded from the archive. A workaround for this is to have an empty file, which forces the game to look for any extracted files.
This plugin changes the order of loading .ini files, if a file exists in a raw state - it will be loaded first, then .pak will be checked second.
PAKPatch requires Ultimate ASI Loader.
