I FOUND A DECOMPILED VERSION OF B1.3.1 LETS GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
Here you can find it if you want to compile it yourself...
This means that i can port over B1.3.1 to Gamemakerstudio 2, which is less dificult than YYtoolkit!
