Hardware specification

Specification of our nintendo 3ds

  • New 3DS
  • Firmware: 9.9.0-26E

General

Hardware
  • Processor in N3DS: Arm9, and also Arm10?
3DS variants
  • There are 3 types of 3DS:
    • The 2DS
    • The O3DS, the original 3DS (aka. Old 3DS), and
    • The N3DS, the new 3DS that features among others a new StickC button.
Firmware
  • The N3DS CANNOT be downgraded to 4.x firmware

Glossary

Sources: [1]

  • NAND
  • SysNAND refers to the original data/system information on a NAND chip embedded in the 3DS.
  • EmuNAND refers to a backup/copy/emulated version of your SysNAND that runs off the SD card.
 The best SySNAND version (i.e. System Menu version, see below) for now is 9.2.
  • SD Card
  • 3DS microSD card -- The 3DS comes bundled with an SD card (O3DS) or a microSD card (N3DS). When EmuNAND is setup, it contains two partitions.
   The EmuNAND partition, when present, is formatted via the homebrew program EmuNAND9.
   The other partition stores homebrew, custom themes, save files, eShop and .cia home menu channels. It must be formatted as FAT32, cluster size 32kB.
  • Gateway microSD card -- On system with flashcards (like Gateway or Sky3DS), there is a second microSD in the flashcard that contains ROM games (.3ds or .3dz rom images).
  • Firmware / System menu
  • System Menu -- This is the official name for "_firmware_" running in the SysNAND.
  • Custom Firmware, CFW -- A program launched by an exploit (like DS profile exploit or MenuHax) that patches the System Menu in memory, and then "jumps" back to it.


Games

  • Look on 3dsdb.com for the releasename of a given game (for instance New.Super.Mario.Bros.2.EUR.3DS-CONTRAST for _New Super Mario Bros 2_).
  • Search the releasename on Google.
  • Download.

How-to

Transfer file from PC using microSD Management

From [2]

  • Go to device setting, and microSD management
  • Enter user name, password, and device name.
  • On Linux, use command:
mount -t cifs //DEVICE_NAME/microSD /mnt -o user=USER_NAME,password=PASSWORD,ip=IP_ADDRESS,servern=DEVICE_NAME
  • Use pv to copy and have progress bar:
pv myfile > myfile

Downgrade the firmware

https://gbatemp.net/threads/simple-guide-to-downgrading-your-3ds.407888/

Info

  • microSD card
The 3DS comes with a pre-bundled microSD card that is used to store user custom data like themes, but also pictures. We refer to it as the 3DS microSD card.
In a system with a flashcart, there is actually a second microSD card, in the flashcart itself. This is flashcart microSD card, or for gateway users, the gateway microSD card.
  • Sysnand vs emunand
Sysnand is the real nand memory on the 3DS itself, containing the original 3ds fw. Emunand is the one emulated on the 3DS microSD card.
  • Homebrew vs Gateway (flashcart) exploits
Howebrew only requires a userland exploit to launch. Gateway requires a kernel level exploit. So homebrew can run on more recent sysnand version than gateway does.
See this comment for a detailed answer.
Gateway's firmware is updated instead to run its exploit on specific sysnand versions.
...
And Gateway won't support 10.5 in the near future, as homebrew and Gateway (or other CFWs) are completely different things. Homebrew can be run with a userland exploit (some rights on the system, but nothing severe), while Gateway, rxTools, etc. need a kernel exploit (execution and manipulation rights for many parts of the console's memory, only achievable through exploits that can be run in userland mode).
  • Sysnand >9.2 support by gateway
Pending. See this comment and follow-up answers.

Reference manual

Reference software

Including the Menuhax manager

Setup

  • New 3DS with firmware 9.9.0-26E (Out-of-the-box, ie. no WiFi profile, etc).

Firmware downgrade

  • Using 9.2.0-20E(Full)_n3DS.zip downloaded from here (google query [MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions))
 (md5sum)     aaa5960a3061da1f08d944d8e7017bd6  9.2.0-20E(Full)_n3DS.zip
 (sha1sum)    306d0aa8cd195f9ee4388a9686db5658a330b59b  9.2.0-20E(Full)_n3DS.zip

 (not the same as the one reported on gbatemp forum thread, but as reported by some commenters, these work as well)
  • Before update:
  • Reset DNS settings to 'Auto-obtain'
     Just in case the downgrade process fails and we want to resort to recovery mode.
  • Used SafeSysUpdater
  • Had to retry 3 times (updater froze at #7 Clean memory...)
  • After update, got the system error message from nintendo, so power down the system.
  • Black screen after reboot. To fix that, remove the microSD card.
  • Back up the microSD card on PC, and delete all content.
  • UPDATE Actually the nintendo error message indicated the downgrade was wrong (even though the 3DS menu showed v9.2).
  • Solution repeat the process again until it says 'success'!
  • Reference:

Install

Summary:

Entering the gateway menu. We follow the Gateway manual:

  • We must create a new WiFi profile, but also prevent firmware update. For this, we use custom DNS settings.
So create a new WiFi profile on the 3DS manually, with
  • SSID / Security: enter your WiFi settings
  • IP Address: Auto-obtain
  • DNS: DO NOT auto-obtain. Set primary DNS to 107.211.140.165, and secondary DNS to 107.211.140.065.
(The gateway manual refers only to 107.211.140.065. Got both addresses from here.)
Run a Connection Test to make sure the WiFi settings are correct.
  • Go to Home Menu Settings, and select Change Theme. Select a random theme (like red), and back to Default.
This is to make sure the required files are created for the MenuHax to work.
  • Power off the 3DS, and move the 3DS internal microSD to the PC, then:
  • HBL Starter Pack -- Extract starter.zip to microSD root folder
  • GW Firmware -- Copy latest Launcher.dat to microSD root folder
  • GW Firmware -- Extract GW_3DSX.zip to microSD root folder (will create a /3ds/GW folder).
The microSD root folder should look as follows:
3ds/
    CHMM2/

    ftbrony/
    GW/                                <---

  • !!! ISSUE ON 9.9.0-26E !!!
We get the following message:
The Internet Browser cannot be used at this time. Please try again later or in a different network environment.
Solution from https://yls8.mtheall.com/3dsbrowserhax.php:
  • Go to browser, and close all opened pages. The browser should display the empty URL bar (with text Enter a URL or search item).
  • Back to HOME menu, set date/time to 2000/01/01 00:00 (that exact day and year, i.e. year two thousand)
  • Go to browser, and quickly click the setting button (bottom left) and select Settings. Then click Clear All Save Data.
  • Then either scan the QR code using the camera or open the browser, and enter the auto browserhax URL.
  • On launch, the browser will welcome you again. Select your favorite search engine, and then browserhax should start normally.
Don't move back to HOME menu after going to the browser. Also, steps above must be repeated when date reaches January 2. So better install a more permanent hax.
  • In HBL menu, select and start menuhax_manager v2.2. In order:
  • Select Configure/check haxx trigger button. I choose Type 1 with 'L' key.
  • Select Install.
  • Select Configure menuhax main-screen image.
  • Reboot, and press 'L' to go into HBL menu using the menuhax trigger.
  • CANNOT go into Gateway menu
  • Downgrade to 9.2 (see above)
  • Still CANNOT go into Gateway menu
  • --> From the forum, I have to redo the firmware downgrade again. So tried again (had to try 4x). Indeed one file was updated.
  • Now, finally, CAN start the Gateway menu from HBL!

Updating the RED Card

  • Start HBL, and start the Gateway menu
  • Select 'BOOT GATEWAY MODE', press A. Press A again to proceed to update, and press START to confirm. Wait a minute for update to complete.

Backing up the SysNAND

  • In the Gateway menu, select "BACKUP SYSTEM NAND", press A then START to start.
  • When done, move the internal microsd to PC, and move the file NAND.BIN to a safe location (for later restore if needed).

EmuNAND Setup

  • !!! THIS WILL DELETE EVERYTHING ON INTERNAL MICROSD !!! So backup all data first.
  • In the Gateway menu (Don't forget to press L when booting from HBL because RED card is now setup), select "FORMAT EMUNAND".
  • Setup again HBL and MenuHax as usual (since the microSD has been formatted).

Install ROM on the Gateway microSD

  • Format the gateway microSD card in ExFat format (done in Windows 7)
  • Copy the *.3ds file in the microSD root folder.
  • Rename the *.3dz file to enable online play (only if game backup was done from the same 3DS console).

Update to latest System Menu in EmuNAND

  • Done it via the System Settings menu (NOT via eShop, since gbatemp FAQ reports that doing so would actually update the SysNAND).

Restore the extdata backup:

  • See https://3dbrew.org/wiki/Extdata for reference info (extdata identifier)
  • Copied back 00000227 (Mii Maker)
  • copied back 00000228 (Streetpass Mii Plaza)
  • Copied back 0000022d (Face Raiders)
  • Note: had to boot browserHax 3x before could get successfully into EmuNAND.

Install bluecardfix.cia (or similar):

  • Boot into GW Menu using BrowserHax -> HBL -> hold 'L' key and select GW Menu.
  • Follow the GW Manual, but after importing mset_eur.cia, also import bluecardfix.cia (to enable back the Blue GW card).
  • IT WORKS! Don't forget to:
   * Remove DevMenu.3ds for the Red GW (or rename it). To avoid innocent hands to mess with it.

Install OoTHax on Zelda OoT Game

  • Copied the file AQEP.sav (for EUR) to 3DS uSD.
  • Boot into GW menu, insert Zelda OoT cartridge, and select Restore Game Save.
  • Check that hax works: boot Zelda OoT, select 1st save (it's normal it save title exceeds the box), and then press 'A' (Check/Voir) to go to GW Menu.

Will now follow the A9LH guide from Plailect (https://github.com/Plailect/Guide/wiki ).

  • First restore the SysNAND using GW Menu. Scary... but at least I'm sure I start from a fresh state.
I checked that my backup was correctly copied to 3DS uSD (using sha1sum) and that it has the correct size:
+ Toshiba NAND:
1.979.711.488 bytes = 1.84GB
Reboot. We are in 9.2.0-21E. The DS profile exploit is gone.
  • Clean the 3DS uSD: remove /updates, Launcher.dat, and /3ds/GW folder.
  • Part 1 - Homebrew:
  • Install starter.zip on 3DS uSD.
  • Boot into HBL. COnfigure menuhax to Type 1, D-PAD Down.
  • Part 2 - Downgrading:
  • Install PlaiSysUpdater + EmuNAND9 on 3DS uSD.
  • Make a SysNAND backup using EmuNAND9.
Launch EmuNAND9 from HBL (can take several tries).
Go to 'EmuNAND Manager Options', select 'Backup SysNAND to file', filename 'sysNAND.bin'
  • Move the backup to PC.
In EmuNAND9, press SELECT to eject the 3DS uSD, then on PC, copy 'sysNAND.bin' on a safe location, and delete it from the uSD.
Insert back the uSD in the 3DS and reboot.
  • Part 3 (EmuNAND):
  • Setup EmuNAND.
Boot 'Complete EmuNAND Setup'.
  • Copy back files to 3DS uSD
  • Open Cakes from within HBM
  • Part 4 (Getting the OTP):
  • Injecting
  • Injecting FBI into hs.app (Linux fails, but do 'wine cmd.exe', then run go.bat works (ignore errors). Same results as on win7), it gives

DS / DSi game support

Troubleshooting

  • 3D not working on system menu (EmuNAND)
Solution: Close the lid and open it back.
  • Can't boot anymore in Gateway menu using MenuHax? But using BrowserHax is still work fine.
  • Can't open FAT32 partition on 3DS uSD with EmuNAND
On Linux, use instead an SD adapter to read the uSD card.
  • Can't open the exfat partition on linux.
Install the exfat FUSE package (! unstable it seems).

Questions

  • What are _arm9 payloads_?
  • Can I copy the ROM files in a subfolder instead of root folder of the GW uSD card? (maybe look into gbatemp FAQ).
  • What is _themehax_? Is it the same as _menuHax_?
  • What is _rxTools_?
  • Are TWL_FIRM and TWL_NAND the same? From this post it seems TWL_FIRM is correct.

Tips

  • Distinguish EmuNAND and SysNAND
  • (source Gateway manual) To easily differentiate between booting from SysNAND or EmuNAND, just setup folders with initials "S Y S" for SysNAND, and "E M U" for EmuNAND.
Not that setting a theme color does not work since themes are shared by both NAND.
  • Boot back directly in SysNAND*
  • Simply go to the System Settings, and leave. LEAVING SYSTEM SETTINGS !ALWAYS! RESUME INTO SYSNAND, SO BE CAREFUL NOT TO DO ANY UPDATE THERE!

Shortcuts

  • hold 'L' when booting Gateway menu --> Go into Gateway menu.
  • In gateway menu, hold down + B to power off.
  • In GW Menu, HBL Menu: 'B' is often used to exit.
  • Hold D-PAD Down button while booting to boot into HBL (MenuHax shortcut, configured as Type1).

TODO

Possible to whitelist back: [29]
--> A long thread about possibility to patch the official sysnand.
--> Better to use bluecardfix.cia instead.
Apparently it is recommended to install them both on SysNAND and EmuNAND.
Some installers (it seems):
  • FBI (open-source)
  • BigBlueMenu
  • DevMenu
gbatemp FAQ suggest to inject FBI in H&S App, then install DevMenu using the injected FBI.
Some reports says that FBI does not work as well as BBM or DevMenu.
  • It is possible to host the BrowserHax locally (on an intranet)?
Should be simply a matter of extracting the repo locally.
Not however we can't bypass 9.9-10.x enforced update this way since the 3DS must connect to Nintendo first (link),
unless of course date/time is set to 2000/01/01 00:00.
  • Boot into GW EmuNAND directly (link, links). Several options:
On this page they speak about UNLINKING the NANDs:
  • Format the SysNAND without any 3DS uSD card inserted.
Some suggestions:
  • Use hblauncher_loader instead of using MenuHax on the EmuNAND.
  • Menuhax / CtrBootManager to cold boot into RxTools, then use hblauncher_loader from EmuNand to boot into HBL. Make sure to add an entry for HBL to CTRBootManager to avoid a boot loop.
  • Boot directly into Gateway EmuNAND
  • Install bluecardfix.cia
  • Much better hax? A9HL instead of MenuHax
  • MenuHax: SELECT on Boot bypass MenuHax?!?
  • About installing bluecardfix.cia:
  • just use patched TWL_Firm (CIA of it is on that iso site, install to NAND) and if needed, TWL Slot-1 Launcher.(install this CIA to NAND as it is a DSi title)
  • Worked like a charm, thanks. I'm guessing bluecardfix isn't compatible with A9LH (Invalid CIA with both dev menu and fbi)
  • So my best option seems to use AuReiNAND + A9HL (see this thread) instead of using bluecardfix.cia.
However I'd like to know what is bluecardfix.cia exactly, what it does, is it revertible, etc.
  • Gateway Emunand to play 3ds files on red card (autoboot) - In this mode, only red card works.
(So here we boot in EmuNAND but using Gateway CFW)
  • rxTools to load same Emunand, but be able to play ds file on blue card. - In this mode, only blue card works.
(So here we boot also in EmuNAND, but using a different CFW than Gateway's)
  • Summary: DS mode does NOT work when booting in Gateway mode (either be it EmuNAND or SysNAND).
But DS mode DOES work in EmuNAND. Just need to install bluecardfix.cia or better yet TWL_FIRM patch or TWL Slot 1 Launcher.
  • Works either in SysNAND or EmuNAND.
  • Only needed for system menu > 4.5.
  • this post: Bluecardfix.cia/DSWHITELIST1.0.cia runs in DS mode. TWL_FIRM is *DSi MODE*.
  • this post from Tony_93 suggests to install bluecardfix.cia both in EmuNAND and SysNAND. Later it explains this is necessary because the system reboots in DS Mode (not emulation), and hence will look for the DS mode in SysNAND.
To install into SysNAND, he also suggests to
  • Boot some CFW into sysnand (PastaCFW/rxTools Pasta Mode/Minipasta, etc...)
  • Boot FBI (homebrew launcher version is fine).
  • Select destination to NAND.
  • Install it.
Or you can boot browserhax > boot PastaCFW > boot browserhax > boot FBI.3dsx > Install to NAND.
  • TWL_NAND: For anything DS related (DSiWare or carts). Patched one will allow the blue card to work (source for detailed installation). !!! One need to patch SigCheck when modifying a system firmware!!!
  • Read these posts and further down about difference TWL_FIRM whatever and bluecardfix.cia.
  • Patched TWL_FIRM can boot Blue GW Card (using TWL Launcher), and can do more as well. But one can boot the card directly with bluecardfix/DS whitelist.
From https://gbatemp.net/threads/gateway-blue-card-not-showing-up-in-sysnand-do-i-need-to-modify-anything.416380/page-4#post-6112460:
I think op is better off by sticking to bluecardfix/DSwhitelist since they are official signed versions released by Nintendo, he won't need a CFW to use it.
If he patches TWL_FIRM he will need to use a CFW permanently to use DS related stuff since you can't run patched firms without having signature checks disabled.
  • this post says that flashcardtimewarp is better because eshop will complain about an update iirc
From this thread:
  • From member _cearp_:
the bluecardfix is v0 of the ds whitelist. it's legit. if you update the fw, you will lose it and you will need to install it again.
flashcardtimewarp.cia' is spoofed to the max version so it is not legit, but it will not be removed if you update your fw.
you basically get the same results no matter what you install
  • From here: After boot strapping the process, install bluecardfix.cia to allow booting the Blue GW Card. On that card, one can start the Gateway menu, which in turn can install the MSET exploit that allows to restore
the DS Profile exploit. MSET.CIA install an old version of System Settings with a hole. This hole is exploited by the NVRAM profile to reboot into GW menu. Running DS Mode game sometimes remove that exploit and
must be restored. GW Menu only install the NVRAM profile. So MSET.CIA installs the exploits. The exploits payload is the NVRAM profile, which sometimes is removed when running DS games. It can be restored by booting into
GW menu. An easy way to do this is to use the blue cartridge (or BrowserHax, or ...).
So
  • MSET opens the door. Must be installed only once.
  • NVRAM profile is the instructions to run Launcher.dat.
  • !!! Careful !!! There is a difference between booting in SysNAND mode and patching the SysNAND. You might write things in SysNAND, but actually these things are written onto the 3DS uSD card, so
possibly affecting EmuNAND as well. Unless EmuNAND and SysNAND are _unlinked_, whatever that means.
  • Enabling DS flash cards:
But this guy says it is a old video and proposes a better one.
New method allows to play from EmuNAND, but with a CFW (not Gateway mode CFW).
  • Seen some post saying they don't need HBL anymore (but for EMUNAND9 and DECRYPT9). They do everything in RxTool/CtrBootManager.
  • Formatting EmuNAND: Can be done with Gateway, but EmuNAND9 is best option because open-source and optimization (source). What are these optimisations?
  • Gateway mode = Go to EmuNAND from a Gateway red card (triggered when selecting "Gateway" entry in HBL). In that mode DS Games, DS flashcards, GBA and DSiWARE games won't not work
  • From FAQ, there are 2 EmuNAND mode with GW: EmuNAND Gateway and EmuNAND Classic. Both boot in EmuNAND, but the first allows to play 3DS games using GW, the second allows to play retail's game cartdridge.
  • From this announcement:
  • Press B while booting into GW to ask whether to boot in SysNAND (X to confirm). Allows for installing back the NVRAM exploit w/o anything more than the gateway cards. This only requires bootstrapping the process
once (with eg. OoTHax, NinjHax, or BrowserHax...) to install MSET.cia and bluecardfix.cia in the SysNAND, and ever do need these Hax again in the future. (see explanation).
From now on, while in the Gateway menu with the boot icons visible, simply hold B while booting into Gateway mode or Classic mode!
  • THE tutorial to install MSET + NVRAM exploit (and make it STICK): MSET Tutorial
  • Best DevMenu show version 0.15.8(r37904) (source). Do not use version 6.2.
  • To uninstall MSET, simply install the original upgraded version, or restore the untouched backup. Use 3DNUS or 3DNUS mod, and get the titleid
USA = 0004001000021000 9.0-9.5 = v8203 MD5: 5077D839633EC80E7A9D3CA98B794D4B

  • Note that changing the menu theme removes the menuhax.
  • Regular SysNAND size = 0x003B0000 x 0x0100 bytes
  • Transfer to bigger SD card:
  • Copied with pv
  • Backup file content of FAT16
  • In GParted, resize FAT16 (extend to the RIGHT), then format it to FAT32 (label EMUNAND9SD)
  • Copy back the files
  • Unmount the FAT32 partition, edit the MBR sector such that textual part match the MBR record (see below).

  • Get DevMenu / SaveDataFiler from link "[MEGA] Retail Encrypted DevApps! (Caution. These will install to NAND!)" (see guide [30])

Save backup

  • This can be used to backup 3DS ROM / cartridge / eshop / cia games, or exchange saves between all these.
  • For 3DS ROM, select the game using Gateway but don't launch it. For cartridge, insert the cartridge first.
  • Start SaveDataFiler
To backup a savegame:
  • For ROM/cartridge, select CTR Card, or the game id for eshop / cia.
For some games (like Fantasy Life), go to extdata/ and select the correct id (Fantasy Life 00001131).
To restore a savegame:
  • Go to SD tab. For ROM/cartridge, select the file and press L+A. For eshop / cia, press R+A. For extdata/ games (like Fantasy Life), simply press A.
Caution. For card1 games (except Fantasy Life), rename the file 000400000FF40A00.sav to game id.
Caution. For card2 games, the save are stored within the game itself. So for GW rom, the save are stored in the .3ds file on the red gateway card!

  • This can be fixed by patching TWL_FIRM:

       !!! make sure you take the N3DS version (not the old 3DS version) !!!
Problem is we can't install it with FBI, which complains about bad signature stuff. But DevMenu will complain that title already exists, so won't do the import.
So
  • Install DevMenu in NAND using FBI. Make sure it is available in the Home menu.
  • Go in FBI. Delete the Title ID with FBI (double check to make sure you selected indeed Title ID 0x0004013820000102).
  • Then press Home button (DO NOT REBOOT THE N3DS), start DevMenu, and import the original TWL_FIRM file.
  • Note that Gateway DS can be launched directly. Acekard 2i, we need the _TWL Slot1 launcher_.
  • TWL Slot 1 Launcher
  • TWL Slot1 Launcher must be installed to NAND using FBI, or we get the error:
summary: summary_invalid argument (ox7)
description: description_invalid_combination (0x3ee)
  • To delete, in FBI, select destination NAND, select 'delete Title', then select line SLOT1BOOTER (check that title ID matches data above).
  • When inserting Acekard 2i into 3DS, the HOME menu freezes.
  • But still, we get black screen freeze at wake-up from sleep mode. Even though the suspended game is a 3DS (CIA) games.
Only solution in that case is to remove the cartridge and hard reset by pressing power button.
  • Note that on CakesFW, we have to check also option Survive reboots when launching some titles.
  • Available update:

Possible solutions:

  • To update, use the official Acekard Kernel v4.23 (remove everything else on the card).
  • Perso, I did first upgrade with v1.41 (giving Alex Rider icon), then the latest (with horse icon).

Final solution:

  • Update to ak2ifw_update_dsi-v1.42_3ds-v2.0.7z
  • Install bluecardfix.cia (this remove all black list from nintendo)
  • No need for TWL Slot 1 Launcher
  • But we need the patched TWL_FIRM on n3DS (because the acekard2i is blacklisted already beyond O3DS fw4.4.0)
  • Installed latest AKAIO, v1.9.0 (optional)
