hello my friends, ive been watching
tutorials on how to use the gateway3ds in prep for my usage on my n3ds ll. it is to my understanding, that once you are in EMUNAND, you are stuck in it until you run out of battery or turn off the system? and if you do turn it off, you have to redo the whole process with the blue card?
Let me just say first of all that
this is the process for 4.x users. It will likely
be different for all the 5.x+ newcomers.
For current (4.x) users:
When you are in emuNAND, to get back into sysNAND you can:
- Turn off and restart console
- Run System Settings, then press Close
- Run SSB, MH4 etc. then Close them (older consoles)
When you turn it off, to start emuNAND again, you just need to go to: System Settings > Other Settings > Profile > Nintendo DS Profile
You
do not need to run through the blue card process again.
The main time when you will need to re-run the exploit is when you launch a DS game.

(The other times are when you do a System Format, System Update etc.)
Again, this will likely not be relevant to you if you're going to be using the newer exploit.
Rumour has it that we won't need the blue card.
