I was playing Mother 3 translation using NDSGBA. I go to make a save state and it works then I go to the frog ingame and make another, it fails, i save at frog and exit to supercard menu to have it make a sav file. it freezes for 5 minutes i waited hoping it would move on but no. I go to restart my supercard and get the black screen with white text i take it out blow into the ds and do some other thigs i usually have to do to get it to work after one of these errors. it still doesnt work so i put the car into my computer only to see one folder named "n26545363" with nothing in it. I have to format my card and lose 8gb worth of games and hundreds of save files. thats the last time I use NDSGBA on my main card. tl;dr It bugged out ruined my card and I had to format everything.
