Ok, so yesterday i received my Sky card from Yeahgeek and everything seemed to be fine. I transfered a couple fo games on my micro SD card via the diskwriter and my N3DS worked with them no issues whatsoever. Since I already own a GW card I sold my Sky card to a guy for his little 9 year old boy - I demonstrated with my console that the flash card is definitely working in front of him. Fast forward a day and he calls me saying that he literally tried everything and that his console (N3DS XL) is not reading the Sky card which is really unusual since it worked flawlessly on mine. So he tried a different SD card and whatnot, tried a bunch of ROMs but with no success, so I met with him saw what the issue is and gave him his money back and he gave me my Sky card which worked again flawlessly. So Im not sure whats the deal here, i mean the card clearly works on my console but it doesnt work on his? Any ideas?
