ready to use .gci files, if you have a US copy, use gt7e.gci, if you have a PAL copy that asks you between french, german, italian and spanish on boot, use gt7x.gci, and if you have an english PAL copy, use gt7p.gci. Then all you have to do after booting the game is to load the "Exploit" profile and select the "load game" option after loading the profile.
