I have a little problem.
I currently have no Card-Reader, and using DSFTP to acces my SD card.
However lately i got some trouble starting/adding some games.
And i'm pretty sure my card needs a checkdisk run.
I don't know if this already exist, but I'm pretty sure it doenst, cause i ran tru some sites.
So, my idea is a homebrew program called "CheckDiSk DS"
