This mod only works on a jailbroken PS3 with a XIII disc!
**Works on all versions (USA, European, Asian, etc)**
1) Download the PKG file here:
2) Put the PKG into a USB stick and install it on your PS3.
3) Insert your XIII disc.
4) Launch the Infinite Gil PKG. This will load the game with your modified EBOOT.BIN.
5) Go to a save point and then sell or buy something. Once an exchange is done, you will gain 999,999,999 Gil instantly!
Credits goes to hyper2k at CP for the discovery of this cheat and me for making it work with XIII discs. Have fun!
