So far I can edit the file and hash it, make a folder called Test and inside of this folder I made another one called files. Place it inside the JGSME folder and load the "mod"

Is your hashed file inside \Test\Files\ ?

Some mods work by just dumping them into the Files folder, but some don't. It's possible you need to duplicate the complete path to where those files reside in the game. I would suggest doing that in the MODS folder, rather than the Files folder, so you don't accidentally pooch your game.
