Looks like a corruption of a bad file/rom.

I think there's a way to back them up with a program, but I forgot which.

But it looks like you might need to format

I heard that Tetris Grandmaster homebrew (the one you can see on the picture as 'NDS_TG~1')
can corrupted the files on your micro sd so always remember...


ALWAYS BACKUP FILES

hah i wondered why TDM was the only file that was untouched

but anyway i managed to get my save files back
i used the startup fixing tool of winxp to fix the files on the sd card
after that all the names of the files are messed up, so i picked all 512kb files and tried them one for one with my pokemon rom =p (was the only file i really wanted)

hope it helps some ppl with the same problem
