Hacking GH customs savefiles

[ether2802]

Hi there, I created a RB:TP vol.1 into an AC/DC .iso, so the custom and the normal are using the same save file,
how can I change the iso's ID inside the WBFS partition on the custom so it creates its own save file...??
I tryed ISO renamer or some app like that, but it only change the ISO ID, the savegame is still the same for both games

if you are using guitar hero 3 or aerosmith as the base ISO for the custom, you can use theghostISOtool to change the save ID. if you are using any other game, it can be done with dack's tool. i believe it comes in the wiiscrubber rar with that program and the partition builder. either way is basically the same, as theghost's tool uses dack's method for it, but just makes it more automatic.
