My gateway card just arrived today (yay) After playing Dream team for 2 hours, I saved and closed it via the home button so it would save. The closing software screen stayed on for a good 3+ minutes. After it finally finished. the save data was corrupted. I know this can happen from time to time, as I already did a bunch of google searching. However, after more testing, it seems to happen on the Closing software screen ever single time. Would this be a problem with the SD card in the 3DS, or the micro in the red card.
