I'm not sure if this is the correct place for this but I have a 3ds xl at ver 6.2 I am going to buy a Sky 3DS because of the need to go online to use my Gateway. The question is should I update the firmware now while the current version is supported or leave it where it is?
Imo, I would say use the gateway exploit to downgrade to 4.x so you can use the D's profile exploit, which is offline. Then you can set up an emuNAND so that he can be on emuNAND 9.5 and sysNAND 4.x. It is more future proof considering the ability to install CIA files manually in case you are blocked from the eshop for any reason.
If you insist on a sky3ds, I would update to 9.5 now, and never update past it before checking the sky3ds website to confirm it's safe. We don't know when/if it would ever be blocked, but you don't want to be stuck on 9.6 with a sky that doesn't work, and no chance of going to gateway.
Either way, I suggest making a NAND backup via GW. You don't need the cart to make it, but it will give you an option in case you get stuck on a fw that is not supported by either cart. You would be able to downgrade from any firmware
