Hacking Luma3DS - Noob-proof 3DS Custom Firmware

[MSearles]

I use a 9.2 emunand as a backup so I can run any homebrew, like Decrypt9.
Arm9loaderhax allows me to play my games on my 10.6 sysnand.

So that's why you would need two EmuNAND firmwares, one 9.2 and one the latest firmware? Because homebrew doesn't work on the latest EmuNAND firmware?

We don't need two emunands. Only one, on 9.2

I'm sorry. I'm just trying to figure Aureinand out. There's three different ways you can use Aureinand. Booting to system updated, booting using Firmware90, which boots to 9.2 Emunand, and booting to regular emunand, which boots an emunand that can be updated to the latest updated firmware. I'm trying to figure out why I would need two different emunand, what the point would be.

You don't need two emuNANDs. If your sysNAND's on 10.6, then your emuNAND should be on 9.2, with both firmware files in the /rei/ folder on your SD card.

When we boot it using ARM9LoaderHax we can have our sysnand on the latest version.
If we use other boot methods then we have to keep our sysnand untouched and update the emunand.

So if I choose to use Emunand on Aurienand using A9HL, sysnand can never be updated? I didn't know that.

There's really no reason to use emunand with A9LH other than as a back up.

Well, both can be on 10.6, there wouldn't be a point for it though.

Can somebody explain the purpose of the [installedal9h] file? I'm having a discussion in my other thread over here (https://gbatemp.net/threads/a9hl-do-i-still-need-emunand-whats-the-cleanest-setup.417423)

If I understand correctly, AuReiNand will always and automatically blocks FIRM0/FIRM1 writes without the need for any files on the SD card. Is that right? (assuming AuReiNand version >= 3.6 and A9LH installed)

- Added a flag to skip decrypting and patching FIRM and use the already patched ones, for a slightly faster boot and to avoid writing 1 MB to SD on each boot. Warning!: You MUST remove the patched firmwares in the rei folder after switching from a non-A9LH usage to A9LH. You have been warned! Original idea and patch by Fix94.
Create an empty file called "usepatchedfw" for this in the "rei" folder. For me it saves like a second on New 3DS.

Thanks for the update

By non-A9LH usage you mean..? If we ever restored NAND to one from before A9LH?

If someone uses this without a9lh (menuhax, etc.) and then switches to a9lh, the old FIRMs are no good (no FIRM writes patch, wrong 9.0 patched FIRM...)

Ah yes, got it. Thanks

Ok i need some help, sorry to be a bother ive been pretty good when it comes to 3ds cfw and homebrew. Anyway im running aureinand 3.6.1 with A9LH on a N3DS and cant seem to get GBA vc games to run at all. I patched agb firm on both sysnand and emunand but cant run GBA in either environment including sysnand with 9.0 firm. can someone tell me what im doing wrong or how to get it working please. Strange thing is on my friends O3ds which i did for him with the exact same set up and patched agb firm his works fine but mine doesn't. Is there a different method for N3ds?

There is a different agb_firm yes so make sure you didn't install the o3DS one

 

[Tylersilva93]

No i know that, i personally patched both agb firms using Agb firm sig patcher. I used the old3ds and new 3ds specific files respectively, the new 3ds patched agb firm is indeed the one i installed on mine

Is there really any benefit to use sysNAND over emuNAND?

It'll probably shave off a second or two from boot times. You don't have to install GBA/DSiWare twice.

Other than that, they're the same thing.
