Would I be able to run GBA games with unlinked Nands?

Yes install on both

I have a little minor issue.
You see, the emunand I created (which is the one I flashed to sysnand) had another user for the eShop/Personal Mii.
It was the previous owner of the 3DS.

Now my question is, how would I go about formatting the current Luma3DS+A9LH 11.0U sysnand to only delete NNID and Miis?
Should I do it the normal way through System Settings -> Format System Data or should I use Tiny Format instead?
Would Tiny Format remove NNID and such while keeping everything else intact?

I'm mainly interested in just keeping FBI injected into H&S.

I managed to remove the NNID and the Personal Mii locked to the 3DS by running TinyFormat once.

Thankfully, it doesn't touch the injected FBI app, so I could install everything back without issues!

Not sure who can help here, I have 3 N3DS XLs, and have Luma3DS on all of them. Decrypt9 is always the start button. So I'd do start_d9.bin, and hold start and press power. I just have set up a O3DS with this, named it too start_d9.bin, it didn't work, so then I tried right_d9.bin, held the right d-pad, and it didn't work. It's on 5.5, not sure what could be contributing, help?

EDIT: Nevermind, restored a sysNAND backup, updated it to 11.0, forgot I just removed A9LH. Time to hardmod.

I have a question. I have emunand on my current setup (3DS LL) and I'm using Gateway (because it's much more comfortable for me). I'm thinking about moving to a9lh, but one thing is dealbreaker for me. Is it possible to use my current emunand as main system with a9lh? I have linked nintendo ID, with few things which I bought on in eshop, I just want to use it as it is.

Yes, you can use the same EmuNAND.

Is it safe to use GW with Luma3ds in sysupdated mode ?
Do GW write some file in sysnand or something like that ?
And if I use GW, what's the best launcher.dat to use ? 3.7.1 ? 4a ? 4b ?
Thank you.

Hi!
I have O3DS XL with 4.5.0-8E firmware with Rxtools emunand.
Is there a Mset loader nds file for luma?
Or is just bootable with Menuhax and Browserhax?

no, Luma3DS doesn't support mset or any version below 7.0

I have been away from the seen for quite awhile and finally came back to see what I have been missing. Obviously, there has been a lot of developments. I'm looking at changing over RxTools on an O3DS to Luma. I have gone through the wiki and tried to go through the thread some (but let's face it, once it gets past 100 pages of posts, it is next to impossible to properly read it). Are there any pitfalls to worry about or is it pretty much copy the files to the SD card and go? If this has been discussed eons ago, sorry I overlooked it.

Been reading the help section of Luma (https://goo.gl/dUZIhr) for fixing problems after a Gateway Downgrade. Seems like it only works for 9.2, I'm not sure how to get to 9.2 safely from downgraded 4.5 ?

Are you sure you're running the latest version of Luma? Copy the Luma3DS.dat and the boot.3dsx that you're using to launch it from the 5.5 release again.

Hello, just replaced files...and it's working! Quite a weird bug! Thanks for the help

I found a bug!
When I want to add a friendcode to my friendslist it says that I have to update, because I'm not on the newest version (11.0.0-33E at the momen). But I am on the newest version. It also don't show up that I'm online.
When I start rxTools everything is fine and I'm abel to add friendcodes.
My friend also have the same problem.

I'm using an old 3DS whit sysNAND 9.2 and emuNAND 11.0.

Ok. Now I am using 5.5-Dev instead of 5.5.
Everything is fine now.

Thanks (y)

Thanks for the link, I'm read over it seems to make sense. Would people recommend using https://github.com/Plailect/PlaiSysUpdater over the normal sys updater because of the cai validation ?
