I figured this would be the best thread to post this question. If not, sorry about it.
Recently, I have found my old white GC memory card, the one that can hold 1019 blocks of data. I have a lot of save data on it, and I'd like to replay some of the games from it on there. The problem however, is that it is corrupt for the most part.
By the most part, I mean that a few games still have their save data intact and are fully playable, but other games will not read the save file and say stuff like "This file is corrupted, delete it" etc.
I've tested Pokemon XD, Colosseum, Melee, StarFox Adventures and Luigi's Mansion. The first four did not work, but Luigi's Mansion seems to be intact.
There are other game save data on the card, but I haven't tested those games out yet. But anyway, onto my question, is it possible to "un-corrupt" those save files? I'd really like to not lose such data on the games, as they are special to me. I'm almost positive there would be a program I could use on the Homebrew channel that would help me out.
If all else fails, is there a way to just completely format the card altogether and make sure it'll work from there? I don't think the conventional "delete all the save files from the card" would work.
If it helps any, the GC memory card is Nintendo brand, not a third party one.
Thanks.
