Damn, I've encountered a major problem. I thought I was mister smarty pants, hacking the game files, but any file you choose will end up causing an error.
The profile with the hacked game save, for example "Hacked" will appear like this: *Hacked* and when you try to load it it will say "Unable to load Profile"... damn maybe the designers of this game were smarter than I think.
I'm not sure how Piracy has found a way to get around this...
even if you modify one byte, for example changing "1" to "~" you will get the error. Changing it back to one returns it to normal.
