wtf, i found the rom somewhere and threw it on my ds. When i booted it up it said my card was unformatted. I stuck it back into my computer and it said it found a new drive, i treid to format it but it says it cant find the drive. I didnt safely remove it so could that have killed this card or could it have been the game?
The game data is read from the SD, but the only thing written to it is the save data.
And according to you, you didn't even start the game, because the flashcart said your card was unformatted before you had a chance to.
So how could it possibly have been the game?
It might have been a bad MicroSD reader (which might mean it's permanently destroyed), or just normal filesystem corruption, which is formattable.
Not safely removing usually won't corrupt the whole MicroSD, however it can corrupt single files if you pull it out while it's writing a file.
If you use Disk Management to format it, it might work. (Go to Start->Run and type diskmgmt.msc)
It always works for me when I can't format it from My Computer.
Actually I usually format it from Disk Management anyway, but still.
