Homebrew Arm9loaderhax and emuNAND questions

[Treeko]

Alright last month I downgraded my 3ds to sysNAND 9.2 and installed emuNAND which was a pretty long process because of me being a noob with all the 3ds hacking, now though there are newer and better methods with better performance for hacking a 3ds, I've been seeing the arm9loaderhax master race pick up steam lately and wanted to join it for future proofing and better bootrate into emuNAND, I have a o3ds with emuNAND and rxtools installed and a ton of 3ds titles installed on it, my only concerns before trying to install arm9loaderhax is will I lose all my installed titles and save files on emuNAND?

I have other questions too, I am still a noob in the 3ds hacking scene, does emuNAND have its own sysNAND partition? For installing gba games I have been seeing that you need to patch stuff up in sysNAND to install gba and dsi titles in both emuNAND and sysNAND, which is odd because I can't access the bigbluemenu in sysNAND because it only shows up in emuNAND its pretty confusing, I did a little bit of research on this and found out that rxtools has its own sysNAND? But I have no idea how to access it because my 3ds is set up to launch straight into emuNAND via the coldboot method.

Sorry for all these questions apparent noob here guys.

Right now, a9lh is like menuhax + coldboot but with better bootrate.
If you look for the OTP guide, you'll find a guide explaining how to get the OTP (a file needed to compile your own a9lh to use this exploit) and at the end, what do you have to do to restore your emunand and sysnand to how it were before all the process.

Sysnand (your current 3ds system) has info stored on the SD card (most of them are information about the games you've bought, how your home menu looks like, saves, etc) and has a core (more or less where the essential information is stored, like updates, wifi and titles regarding the services your 3ds offers to you). This core is usually called NAND and is stored in an internal memory that it's not accessible by normal means.

An emunand is an exact copy of all the system I've explained above with a tiny difference.
the nand (the core of this "EMUlated system") is stored on a hidden partition on your SD card.

So you have:

Sysnand (your normal 3ds)
-Extdata (where your games are stored) -> stored on your SD card
-nand (where the important information of the system is stored) -> on an internal memory

Emunand (your emulated system)
-Extdata (where your emunand's games are stored) -> like in sysnand, stored on your SD card too
-nand (essential info and apps of your emunand) -> we emulate the internal memory on a hidden partition in your SD card and because it's hidden, you will not be able to see this information on your PC when you put your SD on it, you will see just the extData of your emunand and sysnand, games, etc

Thanks for the reply, so if I restore emuNAND and sysNAND after backing them up as they are currently, before following the otp guide, I will be able to get all my installed games and saves of the games back? Or will they be lost thats my major concern because it takes way too much time to install 2gb+ cias.

If you follow the OTP guide step by step, you'll end with your 3ds just as it is right now

If you're following the OTP guide backing up your SD card and your sysNAND/emuNAND should be in it. At the end of the tutorial if you haven't bricked from the downgrade/upgrade via sysupdator you'll be asked to restore your nand from the original backup you made at the start and then delete the contents of your SD card and copy those back over from the folder you'd have put them in from the beginning and when you reboot your games will be there.

Thank you guys for the answers.
