I was given an older 3dsXL (on 4.5.0 by a co-worker, that came installed with a Gateway cart. He paid me to set it up for him when the cart was first released years ago, but stopped using it, so he gave it back to me. It already has a few games saved on it, but I want to make the 3DS as easy as possible for my girlfriend to use, as if it gets to complicated she just won't use it. I did my initial research, found guides on installing CFW on it, and figured I'd just go that route. But it raised a question, so I ask for your advice: For a 3DS that needs to be as user friendly as possible, if you were in my situation, would you update and continue using the Gateway cart, or toss the card to the side and follow a guide to install arm9loaderhax? She will not use it for anything other than strictly playing backup carts, and legitimate carts (she worked at a pawn shop so we ended up with dozens of random 3ds carts, and 5 copies of every Pokemon game). Obviously if I didn't already have the gateway, I would just install arm9loaderhax, but since he already has the Gateway with it, I figured it's worth asking for a few opinions. Lastly, I did a bit of googling, but I couldn't find an answer, is there any special protocol going from a gateway with its NAND emulation (4.5.0 with a higher update installed on a sd card), to a clean install of arm9loaderhax? It doesn't look like it, but worth asking. Thank you in advance for any advice.
