I have three 3DS systems, and they basically all just share one gateway red card. I have menuhax on two of them, and the DS settings menu entry point on another. They all have shit installed on their emunands, and I like being able to use the red card to store 64GB of .3DS files without mucking around with .cias and installations. Seems to me getting A9LH and cfw set up would just make my setup more of a pain to work with. Are there any overwhelming benefits I should consider?
