I have a 2DS, running 6.1 sysNAND and I'm running into a somewhat of a weird issue with emuNAND. After creating my emuNAND (Fresh, nothing edited/installed/modified), I cannot load it using Gateway's "Boot into Classic Mode". Simply booting with rxTools it also fails. HOWEVER, if I press the 'R' button during rxTools loading, and launch through the menu there, it works fine.
The reason I want to launch it through Classic Mode through Gateway is so I can use sysUpdater on my emuNAND. There is also the question of me probably migrating to cakesFW soon, and I'd like to have that problem sorted before that.
In any case, I could live with that. IF nobody knows a solution, I'd really appreciate if somebody gave me some concrete information about updating the 3DS with 3DNUS, such as whether I overwrite existing titles, or just install new ones.
Thank you all in advance.
