I just got an R4 SDHC have copied the latest menus system files to a formatted SD card (formatted a dozen times with the SD Formatter tool as directed as well as through the OS) as well as a few ROM files. The ROMs play fine, but when I enable RTS, the system will lock up on Creating Save File and I to exit back to the 3DS system to regain control. If I press Start on a game, it give me the error codes 81 and 83 telling me to format the card. I have done that too many times to count.I tried copying one only ROM with a short filename and got the same results. Can you please tell me what is wrong? Also... is it possible for an R4 card to brick a 3DS? I've seen where the Gateway cards are known to, but I haven't seen any reports of this one doing so... Thanks.
