i just bought a new DS Lite to use with my old R4 that i've had stored away for about 2 years doing nothing. i tried putting it in the DS today and it wouldn't work at all to begin with, so I tried the trick I saw in a video linked on here somewhere where the guy puts a piece of card under the contact. This time i got an error saying 'SD/TF card error'. I have all different things, like using Wood R4 or the original firmware, using FAT16, FAT32. Does this error mean my R4 could still work and the contact is just a bit messed up, or is there a chance its become faulty after being out of use for so long?
