Installing Unlaunch

::: warning

If you do not have access to a PC, or if your PC is running ChromeOS, then please do not install Unlaunch. A PC (running Windows, Linux, or macOS) is required in order to fix some issues that may occur after installing Unlaunch.

:::

::: danger

If you have not yet done so, please follow Dumping NAND. While the chances are slim, Unlaunch can accidentally brick your Nintendo DSi. A NAND backup + hardmod would allow you to restore this backup, provided you know how to solder.

:::

::: warning

Make sure your console is charged when following this process. A sudden power loss could result in serious damage.

:::

::: warning

Unlaunch is not compatible with Nintendo DSi development consoles.

Section I - SD card setup

1. Download the latest version of Unlaunch
   • Mirror link, if the above doesn't work
2. Extract UNLAUNCH.DSI from the unlaunch.zip archive and place it anywhere on your SD card
3. Verify you still have TWiLight Menu++ on your SD card
   • If you are unsure, follow the instructions from the TWiLight Menu++ install guide

Section II - Installing/Updating Unlaunch

1. Open TWiLight Menu++
   • If this is your first time installing Unlaunch, relaunch TWiLight Menu++ through the exploit that you used
   • If you have already installed Unlaunch and are looking to update it, hold A + B while booting and select the option labeled TWiLight Menu++
   • If several options are labeled TWiLight Menu++, select the option in where BOOT.NDS is shown at the end of the path on the bottom screen
     • This happens because you are running an older version of TWiLight Menu++, unless you're doing it on purpose, is suggested that you update your installation
2. Launch TWiLight Menu++ Settings
   • If you haven't changed your theme, press SELECT and touch the small DS icon on the bottom of the touch screen. Otherwise, see the TWiLight Menu++ Manual
3. Hit L / R or X / Y until you reach the Unlaunch settings page
4. If you want to change Unlaunch's background image, select Background and choose the one you want
   • If you want to create your own Unlaunch background, see the DS-Homebrew Wiki page
5. Exit TWiLight Menu++ Settings
6. In the file navigation menu, launch Unlaunch DSi Installer
   • If you see two black screens after launching, download GodMode9i, put its .dsi file on the SD root, then launch GodMode9i using TWiLight Menu++, and start Unlaunch.dsi
     This method does not enable Unlaunch to use custom patches and background
7. Select the "install now" option
   • If Unlaunch freezes at ERROR: MISMATCH IN FAT COPIES, please take a look at the Troubleshooting page
8. When completed, reboot your system

If you see Unlaunch's Filemenu screen at this point, you have successfully modded your Nintendo DSi.

• If you see a black screen, please take a look at the Troubleshooting page

Section III - Post-Unlaunch configuration

Currently, Unlaunch defaults to launching its Filemenu on boot, but this can be changed launch whatever you want.

1. Power on your console while holding A and B
   • This should launch the Unlaunch Filemenu
   • If nothing is listed, or if only TWiLight Menu++ isn't listed (even after scrolling down), then you'll need to reformat the SD card
2. Navigate to OPTIONS, and look at the available options
   • A + B is hardcoded to launch into Unlaunch's menu, and as such cannot be changed
   • The NO BUTTON and BUTTON A / B / X / Y options can be set however you like and will choose what your DSi loads at boot depending on which buttons are held. You can select any DSiWare, homebrew, the Slot-1 card, wifiboot, or Unlaunch's Filemenu
     • For TWiLight Menu++, select TWiLight Menu++
     • For the original DSi Menu, select Launcher
   • LOAD ERROR is what your DSi will load if loading what you have set fails, such as the SD card not being inserted
3. Select SAVE & EXIT to save your settings, then turn off your DSi
