This mods was a modified version of GTA 5 Mods Enabler that you can find in on the GTA5-Mods, I have remodified the script to able to use this on RDR2.
The creator was FaZe IlLuMiNaTi and this was a useful tool to enable or disable mods on your RDR2.
To install this, just extract the .bat files in the root of your Red Dead Redemption 2 folder, simply as that!
The function has of the scripts has been made compatible with RDR2, so I add several functions to implemented in scripts like:
EasyHook Files
Rampage Trainer Files
ScriptHookRDR2 Files
ScriptHookRDRDotNet Files
