So I am wondering, does the card work with all 3DS XL consoles? Does it need a special firmware or something? or is it just Copy Files > insert in 3DSXL and go? I am scared to purchase it if it needs a special firmware. I don't want to look and buy a 3DS that needs to have THAT SPECIFIC FIRMWARE. Any help?
Yes, this card works on all 3DS consoles. Depending on who you buy it from, it may need to be flashed, but when buying just ask if it's pre-flashed and will work on 8.x. Take note, this card CANNOT run 3DS ROMs.
