I have TWO separate GC Folders that store Save files for my GameCube games, so it gets a little confusing.
I was a little surprised and worried because I had been doing a couple things with Dolphin today, which I will get to in a bit. So today, when I opened my 20XX Melee ISO (a modded ISO of the regular Smash Bros Melee 1.02 ISO) for about the fourth time this day, an in-game message popped up telling me 'The Memory Card in Slot A is corrupted so it must be formatted.
