## Instructions

### Section I - Prep Work

In this section, you will copy the files needed to trigger both Soundhax and universal-otherapp.

1. Power off your console
2. 將 SD 卡插入至電腦中
3. 複製 Soundhax `.m4a` 至 SD 卡的根目錄底下
   - The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
4. 複製 `otherapp.bin` 至 SD 卡根目錄底下
5. Copy everything from the Luma3DS `.zip` to the root of your SD card
6. 在 SD 卡的根目錄底下建立一個新的資料夾 `boot9strap`
7. 解壓 boot9strap `.zip` 的 `boot9strap.firm` 及 `boot9strap.firm.sha` 檔案至 SD 卡的 `/boot9strap/` 資料夾中
8. 將 SafeB9SInstaller `.zip` 中的 `SafeB9SInstaller.bin` 複製到 SD 卡的根目錄

### Section II - Launching SafeB9SInstaller

In this section, you will launch Soundhax through the Nintendo 3DS Sound app, which will use universal-otherapp to launch the boot9strap (custom firmware) installer.

1. 啟動『任天堂 3DS 音樂(Nintendo 3DS Sound)』程式

   :::

2. 如果您從未開啟過音樂撥放器或曾未聽過撥放器內鳥的提示，請一一略過鳥的提示，並關閉及重啟本程式
   - In this situation, launching Soundhax immediately would cause these tips to appear on every launch of the Nintendo 3DS Sound until this is done

3. 選擇『/SDCARD』，並播放『<3 nedwill 2016』

   - This may take many (up to 10) tries
   - If you see the message "Could not play", you are either on a system version incompatible with Soundhax or downloaded the wrong Soundhax release
   - If it freezes, force the console to power off by holding the power button, then try again
   - If you get a different error, [follow this troubleshooting guide](troubleshooting#installing-boot9strap-soundhax)
