Uchiha Itachi said:1. Yes, the patching technically overwrites the ISO and doesn't create any other ISO.
2. Some patches only change the games "image", it doesn't change the game's database. i.e. Fake kits replaced with real kits.
Some patches changes the game completely by adding addition things that weren't in the game to begin with. Like inserting more teams, more boots, and etc...
Don't worry I think you didn't do anything wrong.
Thanks alot for the rapid answer! Nice to see that this forum is really helpful!
I´ll burn it tonight and then I just have to wait one week for my PS2 to be modded...arghhh!
