3DS Homebrew Setup FAQ

From GameBrew - a wiki dedicated to Video Game Homebrew.

Q: I am on the latest firmware version, is my device hackable? A: Yes, but only by downgrading its firmware (see this).

Q: Do I have to do anything different for New 3DS vs and Old 3DS or 2DS? A: All device models are done in the same way with the software used autodetecting which device you have

Q: How do I update Luma3DS? A: Use Luma3DS Updater

Q: What is the difference between RedNAND and EmuNAND? A: RedNAND and EmuNAND are both different types of NAND redirection with small differences in the way they are handled behind the scenes. The main advantage to using RedNAND instead of EmuNAND is that RedNAND will always use the smallest NAND size the device offers, regardless of the size of the SysNAND chip. For example, a New 3DS user with a 1.8GB internal NAND chip will only have to use 1.2GB for all RedNAND backups.

Q: I heard about this thing I have to pay for (Gateway, Sky3DS, etc), is that something I need? A: No. arm9loaderhax is a superior method of loading hax that runs early in boot and opens up the opportunity for things such as true custom firmware.

Q: How do I move saves from an existing Gateway setup to device installed games? A: See this

Q: What do I need to do this guide? A: This guide can be completely done with free software and (if you have no browser) a compatible game

Q: How risky is hacking my console? A: Bricks are now basically impossible unless you ignore/circumvent all safety checks.

Q: Can I pirate games with this? A: Yes. Do not ask me any further questions related to piracy than are answered here, there are plenty of other resources for that.

Q: Can I play online with pirated games without getting banned? A: If you installed the CIA file, you won't get banned. If you are using a flashcart, you might be.

Q: Do I need this thing I heard about called a private header? A: Those are only needed for flashcarts, not CIA installed games.

Q: Can I run awesome homebrew and emulators with this? A: Yes! Custom Firmware not only enables the Homebrew Launcher, but it also will give you hacks on all versions, which means you keep it forever, even with updates.

Q: Can I use this to play games from other regions? A: Luma3DS supports Region Free patches, which enables users to install games from any region without any extra modification or steps.

Q: Is it safe to update CFW SysNAND? A: Yes, but if you are feeling apprehensive you can wait until there is confirmation it works.

Q: Where should I go for support? A: For support, ask for help at #3dshacks on Rizon IRC.

Q: Can I do this with a 4GB (or smaller) SD card? A: Thanks to the new CTRNAND method, yes!

Q: Can I use a 128 GB (or larger) SD card? A: Yes, but some users have reported slowdowns when using such large sizes. Note that you cannot format the card with exFAT; you need to format it with FAT32.

Q: How do I move to a new SD card at the end of this? A: Just copy all the files to the new SD card.

Q: Can I keep my NNID? A: If you start with an NNID and follow every step, you will end up keeping your NNID at the end.

Q: What about System Transfers? A: Once you have completed the guide, you can system transfer to and from an arm9loaderhax'd 3DS or 2DS exactly like you would a regular stock console or EmuNAND (you will lose any non-legitimate games/themes/DLC in the transfer; saves will stay even for games that are lost).

Q: Can I do this without a computer (e.g. an Android phone)? A: This guide, as of now, requires a computer to inject FBI into Health & Safety.

Q: Help! Something bad happened and now I cannot boot... A: Please look at the troubleshooting guide.
