Под словом [**Homebrew(хомбрю)**](https://en.wikipedia.org/wiki/List_of_homebrew_video_games) обычно подразумевают программное обеспечение, не авторизованное Nintendo. В качестве примера можно привести разные самописные игры, программы для бэкапа и редактирования сохранений и эмуляторы консолей предыдущих поколений.
In most cases, running homebrew on your console is 100% free using just the Nintendo 3DS Sound app. There are also various other exploits in commercial games and the browser to get homebrew running.
**Custom Firmware** ("CFW") enables you to use more advanced hacks that userland homebrew can't easily do. Например, можно устанавливать неподписанное ПО и запускать его прямо из меню HOME.
Arm9loaderhax is the newest and best method of launching Custom Firmware that gives us nearly full control of the system only milliseconds into boot, which is similar to the effect of BootMii for the Wii.
The benefits of arm9loaderhax over other Custom Firmware launch methods are numerous, and as such it is recommended to use this guide over any other that relies on outdated software (such as menuhax or rxTools).
## What can I do with Custom Firmware?
+ Play all game cards and eShop games, regardless of region
+ [Делать резервные копии, редактировать и восстанавливать](https://gbatemp.net/threads/release-jks-savemanager-Homebrew-cia-save-manager.413143/) сохранения игр
+ Играть в игры от приставок предыдущих поколений с помощью эмуляторов. (на New 3DS производительность выше)
+ Install homebrew titles to your system, and have them appear on your HOME Menu
+ **Before beginning the guide, you must know the risks of 3DS hacking: EVERY time you modify your system, there is always the potential for an UNRECOVERABLE brick. + Вероятность этого крайне низкая, но шанс всё равно есть. Так что убедитесь что вы СТРОГО следуете всем указаниям.**
+ If you have already hacked your 3DS before to get an EmuNAND setup, and would like to move the contents of your previous EmuNAND to your new SysNAND CFW, you should follow all instructions and restore your existing EmuNAND when prompted once you reach [Installing arm9loaderhax](installing-arm9loaderhax).
+ If everything goes according to plan, you will lose no data and end up with everything that you started with (games, NNID, saves, etc will be preserved).
+ **Keep the device plugged in and charged throughout the entire process to avoid data loss or damage from an unexpected power-off!**
+ Your SD card should be [MBR, not GPT](http://www.howtogeek.com/245610/) (the SD card that comes with the device will be MBR by default).
+ If you need to format a brand new SD card, you can use [`guiformat`](http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm) and set to an Allocation Unit Size of 32K.
+ The 2DS is essentially identical to the Old 3DS in terms of software, and that any steps which say "Old 3DS" also apply to 2DS.
