So i played my DS last night like i always do, no problems what so ever. I had just put lameboy and some GBC roms on it. Now this morning i plugged my card to the laptop to put another DS game on it. To my surprise i find out the whole folder is empty, so i check how much space is left on it and it says the card is filled and i got 0 space left. I unplug it and plug it in again, incase it didn't read it properly, but no difference. So i put in the DS again and it says missing DS_Data file or something (can't remember what the file is called) Anyone else ever had this problem, is there solution to it? I've had this problem once before some year ago or so, i think it was caused by an emulator (the SNESemul one i think) aswell at that time but i can't be sure. Was it caused by Lameboy? Or does this happen randomly to any flashcard? I got a 4 week old backup on my non working PC at the time, so i will lose alot of played gametime on my saves, and even some games that i didn't do a backup on since my computer is waiting on a working Graphics Card.
