I'm sending in my 3DS for hinge repair. I've been using an Acekard 2i successfully. A few questions: 1) I'm already backing up my SD card just in case. Do I need to send that in w/ the 3DS or can I keep it just in case? 2) Is there anything on the 3DS memory itself that would indicate flashcart usage? (yeah, I'm paranoid). 3) I checked Data Management and it seems most of the data I can 'backup' is already moved to the SD card. There's nothing, outside of one DSiware title that I had to move. Anything beyond that? Thanks for the assist.
