Copy the entire contents of Patched_Files to ux0:app/GATOROBOT/games.
If everything went correctly, a Patched_Files folder will be created with various files, including a game.win.
Download the patch and extract it in that folder.
In your PC, open the folder where Gato Roboto is installed (Steam -> Right-click on the game -> Manage -> Browse Local Files for Steam, Install Folder Location on GoG version).
Download the VPK and install it on your hacked PS Vita.
It WILL NOT WORK with a pirate copy of the game due to hash check. If you don't have a copy of the game, you can buy it HERE. You need the game files from your legally owned copy.
