50 Faq for you want to hack 3DS/Nintendo Switch in 2019

Here is the complete FAQ about 2019 Nintendo Switch and 3DS Hacking. Following us, you can get detailed information about Nintendo Switch and 3DS hacking with flashcard or without.

Nintendo Switch Hacking FAQ 2019

  • What’s the mean of Hacking ?

modification of a file or a system. For example, a ‘ROM hack’ means a ‘modified ROM’.

  • What’s NXLoader?

NXLoader is an android application that allows you to boot Fusee Gelee payloads via an android device. You will still require a usb On-The-Go adapter and a USB-A to USB-C adapter. If your phone has USB-C already you just need a USB-C to USB-C cable and an android device.

  • What’s Patch ?

When a large program is released that has a bug, a patch is usually released instead of having the user download the whole program again. The patch is then applied to the existing data and fixes the bug.

  • Does my switch support Fusee Gelee/CFW?

 All Switches prior to July 2018 support this. After July 2018 some switches were patched. You can check your serial number here or find a guide to test it here.

  • When can I install cfw/emunand?

You can install cfw right now! the big 3 options right now are ReiNX, SX OS, and Atmosphere. Only SXOS has emunand.

  • What is Jig ?

A Jig is jumper that connects between the first and last pin in the bottom of the right joycon rail, connecting these enables RCM mode while your switch is booting. My best guess is that this is feature included by nintendo for quality control purposes during manufacturing, we will be taking advantage of this to sideload our own software.

A Jig can be anything that connects these two pins, like a paperclip, a specially made one from, or you can 3D print your own.

  • What’s Payload?

This is another technical term, but basically, it’s the code that gets run when one of the above *hax exploits get used. These payloads are often updated by Smealum when new system firmwares come out, or as homebrew programmers ask for new features.

  • What if I upgrade to the latest firmware?

All switches prior to July 2018 and all firmware are supported at this time. If you have newer firmware 5.0+ it only means the easy method will take longer to be released

  • I’m trying to land two switches together and it’s not working?

Both Switch consoles are required to be on the same firmware and have the games running the same updates

  • What firmware can I install homebrew on?

Homebrew can be installed on Nintendo Switch system version 6.2 and below.

  • What is AutoRCM and should I use it?

Firstly, let’s explain exactly what AutoRCM is. In order to get CFW working on your Switch, you must enter RCM and push a payload, which can be quite a pain in the ass depending on what method you are using to bridge the pins on the right Joycon rail. AutoRCM alleviates this by having your Switch boot directly into RCM.

This can be healthier for the Switch as you won’t be tinkering with the Joycon rail on each boot. However, you will be unable to boot your Switch unless you send a payload to it on each boot. If you turn your Switch off periodically and ocassionally would like to boot into OFW (Original Firmware), it’s probably best that you leave AutoRCM behind.

However, if you are just interested in running only CFW and do not want to tinker with your Joycon rail on each boot, AutoRCM is for you! Custom firmware-CFW.

  • What’s NSP file?

A Nintendo eshop game format, similar to .cia files for the 3ds consoles.


You can follow the guide.

  • What size SD Card should I get for CFW?

The recommended size is at MINIMUM 64GB. This is because while the SD card is SOLD as 32GB, the actual formatted amount is ~28-29GB. We will have to store an image on the SD card that is roughly 32GB in size, so no a 32GB card will not work. Personally I’d recommend you use at least 128GB as you must also have space to store games, homebrew, etc.

Note: You should typically go for as large an SD card as you can afford.
(I will add a list of known working cards that I know is floating around)

Note 2: Fat32 can only store files upto 4gb per file.

Additionally if you want to boot linux, you should use a second SD card so you don’t risk losing anything on your main one.

  • Is there a list of all released homebrew?

Yes! You can find a complete list on WikiTemp, or a smaller list on, or even use the Switch appstore homebrew directly on your Switch to browse and install homebrew on your console without a computer.

Note: WikiTemp homebrew list is a work in progress, please help maintaining it.

  • Can I get free games?

Yes you can. SX OS allows XCI loading and NSP installing. ReiNX and atmosphere allow only NSP installing. XCI’s are loaded directly from the sd card or hard drive, as opposed to NSP’s, which need to be installed.

  • Which CFW is superior?

It all depends on what you’re planning on doing. For piracy, I would recommend you use SXOS. You will have to buy a license to use it however. For everything else, I recommend you use Atmosphere.

  • What happens if I get banned? How likely is it that I will get banned from hacking?

Check out the Switch Banning Hub for all your ban-related needs!

  • I heard about a switch emulator!

There are two main switch emulators, Yuzu, and Ryujinx. At their current state, they can run a few games, such as Mario Odyssey, but most games are unplayable.

Nintendo 3DS Hacking FAQ 2019

  • What’s EmuNAND/Emulated NAND/redNAND/redirected NAND/sdimage?

These are all terms for the same thing. They refer to running the 3DS’ OS (Operating System) from the SD card slot of your 3DS, instead of the 3DS’ internal flash memory (called NAND). It provides a safer environment for experimenting with system components as well as running the latest games, while still keeping your hacks.

  • What’s Custom firmware (CFW)?

Custom Firmware, which requires an arm9 exploit to run. Usually its main use is to disable signature checks, and (in the past) boot emuNAND. Modern CFWs like Luma3DS allow for a lot more cool things, like requiring a PIN to start up, and showing the original GBA boot screen when booting a GBA game.

  • What is Firmware (FW) ?

Firmware is the software that tells your device how to run. This is usually updated to provide new features/bug fixes.

  • What’s Hard mod/NAND mod/hardmod/NANDmod ?

These are all interchangeable terms for one thing, which is when the user (or someone the user hires) solders wires and an adapter port to the 3DS, in order to gain access to the internal flash memory. It’s used for making backups, restoring backups, and in some cases, doing a downgrade without a backup .

  • What’s SysNAND/System NAND/physNAND?

This refers to the 3DS’ internal flash memory (and/or the OS itself, when it’s first running/you’re not in emuNAND). If you’re not running emuNAND, you’re in sysNAND.

  • What’s Linked NANDs?

When a user first creates an emuNAND, it is considered to be “linked” to the sysNAND it was created from. This means that the emuNAND will share the same programs, save data, etc., installed into the “Nintendo 3DS” folder on the SD card. This saves space, but also creates a “bug” where games and applications need to be unwrapped from presents on every boot.

  • What’s Soft Mod ?

A method that uses software to modify your switch to allow for running unsigned code. It is usually an easier method than hard modding.

  • What’s .nds ?

A file container that holds a back up of a Nintendo DS game.

  • What’s Kernel ?

The “Operating System” of the Flashcart. E.g. AKAIO, YSMENU, WOOD, etc

  • What’s Backup ?

A copy of an original game. A loose term used to describe a ROM that has been extracted from the original cartridge into a single data file on a personal computer for personal use or archival, or the method for doing so. This can be done using various methods depending on what system the cartridge/disc is for. Also known as “dumping”.

  • What’s Flashcart clone/R4 Clone ?

A copied Flashcart that may lack quality and use of original firmware.

R4 clone : A flashcart that is hardware-based on another flashcart, like “R4i Ultra”, “R4i Gold”. Most clones don’t have any support at all, sometimes the “official” website doesn’t even give the firmware or kernel.

  • What’s Slot 1/ Slot 2 ?

Slot 1: The NDS Cartridge slot. Available on NDS and NDSL.

Slot 2 : The GBA Cartridge slot. This was taken away from the DSi and DSiXL/LL.

  • What’s Clean Dump?

A ROM dump (commonly referring to NDS ROMs), that has not been modified from its original form on the cartridge.

  • What’s DS mode ?

The way all SLOT-1 flashcards run their games, even the DSi compatible cards.

  • What’s DSi enhanced ?

A game that takes advantage of certain DSi features not available in earlier versions.

  • What’s Emulator?

A program for the computer that allows ROMs to be played on the computer. It “emulates” a system.

  • What’s Good/Bad ROM/dump?

A ROM (See ROM) that has been dumped (See Dump) incorrectly, which may cause it to produce errors during execution or may stop it from working as it should. ‘Bad Dumps’ almost always require the original cartridge to be dumped again properly to produce a good ROM (See Good ROM).

This term was originally used for ROMs that were validated by the GoodTools. But we sometimes also use this term for ROMs that are in the scene release lists if their CRC match.

  • What’s Moonshell?

A homebrew multimedia player for the Nintendo DS, Nintendo DS lite and Nintendo DSi dual-screen handheld videogame systems. It is a well known piece of Nintendo DS homebrew software, and offers a way to play videos and audio on the DS, along with other homebrew games.

  • What’s ROM?

Acronym of “Read-only memory”. A ROM is a piece of flash memory that contains permanently stored data that cannot be added to, modified or removed. The term ROM is also used to describe a ROM from, for example a game cartridge that has been extracted and backed up to a single file on a PC. This method of extraction can also be referred to as “dumping” and the end file is commonly called a “dump”.

  • What’s Trim?

“Trimming” means to remove “dummy data” from a ROM file in order to decrease the file size. Contrary to how the majority of people think it works. It simply does not compress the ROM in any way. It’s just a method of removing dummy (garbage/filler) data from the file which can be anything from a few KB to a few MB.

  • What’s CIA?

This stands for CTR Importable Archive. It’s like a WAD file from the Wii days; it’s just a container that contains game files or system firmware updates. Installing these will either install a game (to the SD card) or parts of a system firmware update to your 3DS’ NAND (if on emuNAND, then it’ll obviously install to the SD card’s emuNAND).

  • What’s .3ds?

These are raw cartridge/gamecard dumps from retail-purchased games. They’re typically used by flash carts like Gateway or Sky3DS, but have other uses, such as being converted to CIA format for being installed to the SD card.

  • What’s BBM, DevMenu, FBI, NASA, BigRedMenu?

These are all CIA “Managers” which can be used to install or delete CIAs from SD or NAND. Their exact features or lack thereof won’t be discussed here.


This is a more complicated term, but to put it simply, it is the “kernel” of the 3DS operating system. Nearly every firmware update updates this as well, and as time goes on, games require newer and newer versions of this to function correctly. Having a sysNAND or emuNAND on a certain version does not necessarily mean that NATIVE_FIRM matches or was updated. Do not confuse the two (saying “I’m on emuNAND 15.5″ doesn’t always mean you have FIRM 15.5 as well).

  • What’s hax ?

This refers to one or more (or even all) of the various homebrew hacks below. It uses an asterisk to indicate a wildcard (meaning you can fill in the blank basically). They are all used to run homebrew or boot CFW.

  • What’s MenuHax/ThemeHax/ShuffleHax ?

These are all flavours of MenuHax, which is an exploit in the Home Menu, available on firmwares 9.0-10.5. They crash the Home Menu when the exploit is triggered, instead launching you into a homebrew environment.

  • What’s SmashHax/SmashBrosHax ?

This is an exploit used in the game Super Smash Bros. For 3DS, used to run homebrew on a New 3DS.

  • What’s NinjHax ?

This is an exploit used in the game Cubic Ninja. It was the first 3DS game cartridge-based exploit released to the public.

  • What’s BrowserHax/StagefrightHax/SliderHax/SpiderHax?

These all refer to different types of exploits in the Internet Browser, but they all accomplish the same thing: letting the user run homebrew on their 3DS via the Internet Browser.

  • What’s IronHax?

IronHax was an exploit in the game Ironfall Invasion that had quite a long life, until Nintendo finally put an end to it with system firmware 10.4, refusing to launch the game at all if it’s not updated.

  • What’s TubeHax/TubeHax DNS?

TubeHax was an exploit in the Youtube app that allowed homebrew to launch, but it was fixed in late 2015, so now the term more often refers to the DNS. The DNS is often used on the Wii U and the 3DS for blocking Nintendo updates and update nags.

  • What’s A9LH/ARM9LoaderHax/K9LH/Kernel9LoaderHax?

Describing this in its entirety is beyond the scope of this glossary. However, this hack boots at an even lower level than MenuHax, exploiting the console a few moments after hitting power, instead of waiting for the Home Menu to come up (think BootMii from Wii). Installing it is riskier and more difficult than MenuHax, but most of the install process is automated now. Kernel9LoaderHax is the “technically” correct term for it, but the community generally uses both A9LH and K9LH interchangeably.

Lastly, here are all the 3DS/Switch hacking terms we collect from online and with our knowledge, if you still have more questions on Switch or 3DS jailbreak, you can email to me [email protected], we not only sells you the genuie 3DS/Switch flashcards to play free games easily on the console, but also willing to help you hack the consoles with free ways.
