R4 help!

Recently,I was playing my R4ds.(It was working when i got it 3 months ago.)Then one day,there's a virus that infected one of my names.At first,it didn't matter to me.But then,it infected All OF MY STUFF!!Then,all of my stuff disappeared,leaving files saying ""Does anyone know how to fix the virus and restore my data?

Never saw that before, have you tried formatting the microsd and reinstalling last firmware? (Starting all over again..)

Run chkdsk too.

I doubt its a virus, it sounds more like the file system is corrupted. Reformatting will cure that.

But,what about the games? I didn't back them up... :(

if they're inaccessible then its already too late to recover them.

Noooo!!!!!There's gotta be some way....Or at least make those  files readable.

right click, rename, give it a temp name, use the NDS Header Tool to check which game it is, rename it to proper game. That *might* work, assuming the only that was changed was the filename, not the actual data.

The name can't it be change for some reason....
