Hacking EmuNAND9 has ben updated to support redNand among other things.

[jimmyleen]

As of today (March 25) Emunand9 has been updated to do some new and impressive things.

What the new EmuNAND9 can do:

• Added 'Complete RedNAND Setup' feature
• Added options to convert your EmuNAND <-> RedNAND and vice versa
• Improved SD card and SD card fault handling
• Various smaller and bigger improvements

- Link to the gbatemp thread explaining the difference between GW 3DS and redNand https://gbatemp.net/threads/emunand-rednand-technical-implementation.401969/#post-5783813

- Link to 3drew explaining what nand redirection is https://www.3dbrew.org/wiki/NAND_Redirection#RedNAND


Edit: I have know idea what redNand is, and I can barely find any information about it


Edit: Later on I will buy another N3DS and run this just to see what can be done

Why would you buy another N3DS? It's an emuNAND.

There's tools there to convert existing GW NANDS to RedNAND and vice versa. At worst you'd need a new SD card if you didn't want to bother with backups. It's a bit more efficient, and if you do the full process, shaves off a few hundred MB off emuNAND. For now though that's about it. (also keep in mind Cakes/AuRei are the only CFW supporting it)

TLDR version: Maths. Basically the way each NAND handles writes.
