I an going to mod a 2ds and it has a new main board. None of the pins are labeled and there's no removable wifi card. Are the solder points still in the same location? There hardmod section doesn't say anything about this board.
Although do note that if you have trouble getting it to read the nand, you may need to buy one of the n3ds recommended sd readers as they switched over to the 1.2/1.8gb Nand's used in the n3ds on the new 2ds models (lol, sounds like a "new" 2DS)
