### Required Reading

如果你的3DS之前已经破解并安装了基于虚拟系统（EnuNAND）的自制系统（CFW），请务必注意本教程仅适用于真实系统（SysNAND），并且教程内的所有步骤都应当在你的真实系统（SysNAND）上进行。 注意EmuNAND和RedNAND是[同一概念](http://3dbrew.org/wiki/NAND_Redirection)的两种略微不同的实现。

Soundhax (when combined with pre9otherapp) is compatible with versions 5.0.0 through 8.1.0 in the EUR, JPN, KOR, and USA regions.

To extract the `.7z` files linked on this page, you will need a file archiver like [7-Zip](http://www.7-zip.org/) or [The Unarchiver](https://theunarchiver.com/).

Note that cartridge updates will only deliver updates to core features, such as the System Settings, Home Menu, etc. cartridge updates will not deliver updates to Nintendo 3DS Sound and Network features, such as System Transfer, Internet Browser, StreetPass Mii Plaza, or eShop.

This means that using a cartridge update from a version containing an older Nintendo 3DS Sound version *(<3.0.0)* to one that introduced a newer Nintendo 3DS Sound version will break [Soundhax](homebrew-launcher-(soundhax))! You will need an [alternate method](installing-boot9strap-(mset)) of entering the Homebrew Launcher!

#### Section I - Prep Work

1. 给设备关机

1. Copy `boot.firm` from the Luma3DS `.7z` to the root of your SD card
1. Copy `boot.3dsx` to the root of your SD card
1. Create a folder named `boot9strap` on the root of your SD card
1. Copy `boot9strap.firm` and `boot9strap.firm.sha` from the boot9strap `.zip` to the `/boot9strap/` folder on your SD card
1. Copy `arm9.bin` from the SafeB9SInstaller `.zip` to the root of your SD card

    {: .notice--info}

1. If you've never opened Nintendo 3DS Sound before and get tips on how to use it from a bird icon, go through all of the bird tips, then close the app normally and relaunch it
  + In this situation, launching Soundhax immediately would cause these tips to appear on every launch of the Nintendo 3DS Sound until this is done
1. 选择 `/sdcard`，然后选择"< 3 nedwill 2016"
  + 这一步的成功率不是100%，有可能需要反复尝试
  + 如果直接启动 SoundHax，会让这些提示每次都跳出来，除非你先跳过提示，然后再正常重新启动播放程式
