I've just purchased F-Zero GX earlier today, and I have to admit it's a wonderful game. That is, except for one very annoying and frustrating "glitch": Every time I try to load anything from the Garage save file, it claims it's corrupted, and needs to be deleted. A few times it has even corrupted the entire memory card, and forces me to reformat it. I've tried this with two memory cards: a Mad Catz 4MB (with only the F-Zero GX main save file and Garage save file) and a Nintendo brand Memory Card 59 (with WaveRace, SSB:M, SA2, and Mario Sunshine saves on it).
Only once out of the (at least) 20 attempts was F-Zero able to load the Garage data with no problems, and only after I had moved files around on both memory cards. However, as soon as I saved any changes to the Garage file, the data was viewed as corrupted and deleted once more. I doubt the memory cards themselves are faulty, since the core system is able to access the data with no problems, and my existing save game files still work perfectly.
If anyone has a possible solution, please reply promptly. Thank you.
