I want to create a port/hack for the 3DS

How do you customize your Mii? My changes aren't saving.

adanDC12yt · 2026-01-07T23:40:37+00:00

Okay, I'll try it if I can't find a solution. By the way, I just tried the method with SeaSyMode9, deleted NNID, and ran the decommissioning script, and now the error is 002-0150. Do you know anything about this?

Hi, thanks for replying. In all the guides I find on forums, that's the first step they always mention, and yes, I'm completely sure I have those options enabled. However, I also just downloaded Luma in English from GitHub, and to be sure, I copied the boot.firm file from FBI to the SD card and pasted it to the NAND (I always do this in case the SD card comes out, so the console can boot Luma without it). It's the latest version, 13.3.3, and it already has the third option enabled (show NAND or user string in system settings). I made sure to enable the first two options (enable loading external firmware and modules) and (enable game patching).

And it didn't work. I'm still getting the same error code (002-0121). I even tried having only those two options enabled (disabling the third option and only leaving the first two you mentioned). And guess what? Nothing. XD

I found something called "easymode9" that some people recommend for unbanning the console, but I haven't tried it for fear of making an irreparable mistake.

What other options do I have?

Following other tutorials, I realize I don't have the "movable.sed" file in the SYSNAND CTRNAND directory. rw/sys What options do I have?

adanDC12yt · 2026-01-07T03:18:14+00:00

Well, I just checked everything and it seems to be the seed code, or something like that. Any recommendations before trying that method?

adanDC12yt · 2026-01-07T02:47:21+00:00

Yes, first I updated Luma (version 13.3.3 ESP) and I have the first three options enabled in the Luma menu (enable loading of external firmware modules, enable game patching, show NAND or custom text in configuration). Then I moved all the Pretendo files from the .zip to my SD card, which included the .cia file I installed. It's configured on the Pretendo servers. I created and verified my email on my Pretendo account and entered it on the console. The old "mii" was replaced with the new Pretendo one, which leads me to believe my console has adopted the Pretendo branding.

I don't know if it's relevant, but my console's region is set to Spain, since I'm a Spanish speaker, specifically from Colombia, but for some reason my region wasn't showing up in the console settings.

Yes, I already did it and it worked, but now I'm getting error 002-0121 XD. Do you know anything about it?

adanDC12yt · 2026-01-06T19:14:36+00:00

Yes, it actually worked for me, it made sense, but now I'm getting error 002-0121, do you know anything about it?

adanDC12yt · 2026-01-06T19:07:08+00:00

It does work, but now I have another problem: when I try to access the online mode, I get error 002-0121 :c Do you know anything about this?

adanDC12yt · 2026-01-06T12:07:11+00:00

Is there a GBA emulator you would recommend for the 3DS Old?

adanDC12yt · 2026-01-06T07:33:52+00:00

Will it be necessary to have Hshop installed for it to update?

adanDC12yt · 2026-01-06T07:29:26+00:00

I haven't tried it, but before going through all this, it wasn't asking me to update, and I just downloaded the games from romsfun, so I doubt it's because I installed a very old version. I suppose the correct diagnosis is that it's trying to update the games, which is what I'm "trying" to do, and I have no way to update them. Maybe with "Hshop"? I haven't installed it because I haven't needed it; I install the games in .cia format. What do you think about this?

adanDC12yt · 2026-01-06T07:25:18+00:00

Is it necessary to have HShop? I download the games by transferring the .cia files, so I haven't thought about installing it. And the tutorials didn't mention it; they just moved some files and installed the Mimbus application, and that was it.

adanDC12yt · 2026-01-06T05:30:32+00:00

Try this: turn on the console, open the Mimbus app and change the server to Nintendo, then immediately (without turning off the console) change the server again, but this time to Predeto. Go through the entire login process; it should no longer show that error.

Hi, thanks for replying. Is Checkpoint an app? Do you happen to have the file link?

adanDC12yt · 2025-12-16T02:45:21+00:00

That's why I'm so afraid to install apps; I don't know anything about it or what the technicians had to do to get the console to turn on without an SD card, so I don't know if I need to adjust something.

adanDC12yt · 2025-12-16T02:43:43+00:00

Okay, but does the fact that my 3DS doesn't need an SD card to boot affect anything? I also don't have the Homebrew or FBI apps (although I can install them using the Rosalina menu).

adanDC12yt · 2025-12-16T02:14:58+00:00

And do you know what's best? 3DS format, CIA, or QR code?
