You can use Luma3DS without A9LH.
Why would you ever need to use the 3DS without an SD card, though?
Im doing a bit of homework to see how its done and a shortage of sd cards plus resell value is in question due to where I live.
Don't want the person im sell the 3ds to freak out and think its bricked.
I dislike people who sell you free info, and it happens a lot here. Information is money.
uh, Im not going rage here, it would be rude.
