Would it be possible to download an update for say SSB3DS from 3DNUS or an equivalent program and use the .3DS version of BBM or devmenu to install the update to sysnand? Or is that a no-no?
Im pretty sure its possible but you will need a sysnand that can access eshop updates without needing to launch eshop to download and use rxtools to extract your ticket and download the .cia to your computer using FunkyCIA
plus the update will not work on your sysnand because legit personal cias can only be installed on pbt cfw so you that means the cia that you will install on gw will not be legit, so you will have to copy your legit ticket (the whole ticket.bb really) - from emunand to sysnand.
which can be done by copying your sysnand into emunand and using rxtools to inject the ticket.db and reflash into sysnand using gateway
If you want updates to work in sysnand i think this is the only way but i would just use rx mode personally
sure, it depends if you have emunand already. rxtools is the only way to get online and get something from eshop at the moment basically, apart from that new ntr based hack and using a nand mod.
