Ok so I have the O3DS XL and its got Rxtools on it, I want to upgrade to a New N3DSXL so I have a few questions before taking the plunge. 1)Can the N3ds be downgraded? 2)Can I install CFW and Run CIA's? (Which CFW should I use?) 3) Can I install emuNand and update it to the latest firmware? and lastly 4)is the upgrade really worth it? Any feedback would be appreciated thank you.
