[**Homebrew**](https://en.wikipedia.org/wiki/List_of_homebrew_video_games) usually refers to software that is not authorized by Nintendo. This includes homebrew tools, applications, games, and emulators.
In many cases, running homebrew on your device 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.
firmware to boot9strap powered Custom Firmware. 일부 버전에서는 해당 버전을 벗어나는 발판으로 홈브류를 사용하지만, 여전히 최종 목적은 커스텀 펌웨어입니다.
boot9strap 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. It gives us even earlier control than arm9loaderhax did, and, unlike standard sighax, boot9strap uses an NDMA overwrite exploit in order to gain Boot9 code execution. This means that any console running boot9strap is capable of dumping the console unique OTP (`OTP.bin`), the ARM11 bootrom (`boot11.bin`), and the ARM9 bootrom (`boot9.bin`).
The benefits of boot9strap 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Firmware launch methods are numerous, and as such it is recommended to use this guide over any other that relies on outdated software (such as menuhax + rxTools, arm9loaderhax, or even normal sighax).

## 시작하기 전에 무엇을 알고 있어야 합니까?
+ **가이드를 시작하기 앞서 반드시 3DS 해킹의 위험 요소를 인지하기 바랍니다: 시스템을 수정하는 모든 행위는 기기를 복구가 불가능한 벽돌로 만들 위험을 안고 있습니다. 매우 드물어도 가능성은 존재하므로 모든 절차을 정확하게 따라 주세요.**
+ 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 [Finalizing Setup](finalizing-setup).
+ SD 카드는 [GPT가 아니라 MBR](http://www.howtogeek.com/245610/) 기반이어야 합니다. (처음 샀을 때 끼워져 있는 SD 카드는 기본적으로 MBR입니다.) The easiest way to test this is to check if the SD card works in your 3DS. If it works, the SD card is MBR.
+ If you need to format a brand new SD card, you can use [guiformat](http://ridgecrop.co.uk/index.htm?guiformat.htm) and set to an Allocation Unit Size of 32K (32768). If your SD card is 64GB or larger, use an Allocation Unit Size of 64K (65536) instead.
+ The Old 2DS is essentially identical to the Old 3DS in terms of software, while the New 2DS is essentially identical to the New 3DS in terms of software. Any steps which say "Old 3DS" also apply to Old 2DS, and any steps which say "New 3DS" also apply to New 2DS.
