Memory card says it is corrupted on Mario Kart - Double Dash

[Copeeyy]

the memory card works fine on all games except Mario Kart. For some reason it says it is corrupted and i need to format it to use it. But i dont want to do that because i will loose the saves from my other games. Any ideas how to fix this?

First make a backup of your memory cards incase something happens. Are you using GCI folders or memory cards?
