GMLoader is a program that can load CSharpScript files and recompile non-YYC GM:Studio games, it uses UndertaleModLib as a library to recompile the data.

It will create backup.win at the game root folder and will always recompile from the backup to ensure that you'll never corrupt the data.

Installation and usage

Vortex or Mod Organizer 2 mod managers are supported by GMLoader for some specific games.
You will only need to run GMLoader once everytime your adding or removing mods that requires GMLoader, this will save your time recompiling the data.
