How Risky is Unlaunch DSi?

Unlaunch, a popular custom firmware (CFW) bootloader for the Nintendo DSi, offers a world of possibilities, from running ROM hacks and homebrew to accessing DSiWare directly from your SD card. However, the question of risk inevitably arises when modifying your console’s core software. The truth is, installing Unlaunch does carry a minor risk of bricking your DSi, though the severity and likelihood are often overstated.

The risk stems primarily from the modification of the DSi’s bootfiles. If the installation process is interrupted or encounters an error, the console may become unable to boot either the original firmware or a recovery bootcode from the SD card. This leaves you in a “bricked” state.

While this sounds dire, the reality is often less severe than imagined, with the proper precautions. With thorough preparation and careful execution, the chance of bricking your DSi during Unlaunch installation is minimal. However, it’s crucial to understand and respect the potential for things to go wrong.

The risk is slightly higher if you later attempt to uninstall Unlaunch. That is why understanding the benefits and potential pitfalls is essential before proceeding with the Unlaunch installation.

Understanding the Risks and Mitigation Strategies

The following strategies can significantly reduce the likelihood of bricking your DSi:

1. NAND Backup: Before anything else, create a NAND backup of your DSi’s internal memory. This is absolutely crucial. A NAND backup allows you to restore your DSi to its original state in case of a brick. This requires a hardmod, involving soldering wires to the DSi’s motherboard to access and write to the eMMC chip. While this seems daunting, it’s the ultimate safety net.
2. Follow Instructions Carefully: Meticulously follow a trusted guide, like DSi.cfw.guide. Every step is important, and skipping steps or improvising can greatly increase the risk.
3. Ensure Adequate Power: Make sure your DSi is fully charged before starting the installation process. An unexpected power loss during installation can lead to data corruption and a brick.
4. Use a Reliable SD Card: Use a reputable SD card from a trusted brand. Cheap or faulty SD cards can cause errors during installation.
5. Verify Files: Double-check that you’ve downloaded the correct versions of Unlaunch and any other necessary files.
6. Understand the Process: Don’t blindly copy and paste commands. Take the time to understand what each step does and why it’s important.
7. Careful Uninstall: If you decide to uninstall Unlaunch, do so with the same care and attention to detail as the installation. Follow the exact uninstall instructions provided by the Unlaunch developers.

It’s also important to note that Unlaunch is not compatible with development consoles. Attempting to install it on one will almost certainly result in a brick.

TWiLight Menu++: A Companion to Unlaunch

TWiLight Menu++ (TWLMenu++) is often used in conjunction with Unlaunch. It’s a DSi Menu replacement that allows you to launch DS ROMs, DSiWare, and homebrew applications from your SD card. It even comes pre-installed with retro emulators like GBArunner, for playing Game Boy Advance games.

TWiLight Menu++ enhances the functionality of Unlaunch by providing a user-friendly interface for accessing your games and applications. Installing TWiLight Menu++ itself is generally safe, but always follow a trusted guide and back up your NAND beforehand.

FAQs: Unlaunch DSi

1. What exactly does Unlaunch do to my DSi?

Unlaunch modifies the bootcode of your DSi, which is the first piece of software that runs when you turn on the console. It essentially intercepts the normal boot process, allowing you to boot into TWiLight Menu++, a custom DSiWare application, or the original DSi menu.

2. Can I play DSi games without an SD card after installing Unlaunch?

With physical games, the save files are stored on the cartridge. The SD card is used to store photos, sound files, and digital games. So, yes, you can still play physical DSi games without an SD card after installing Unlaunch.

3. How do I change the Unlaunch background?

Copy the GIF file to sd:/_nds/TWiLightMenu/unlaunch/backgrounds. Open TWiLight Menu++ Settings, switch to the Unlaunch settings page, and click on “Background,” then select the one you want.

4. Can I use a 64GB SD card with my DSi?

Officially, the DSi supports SD cards up to 32GB (SDHC). Although some users have reported success with larger cards, using a 32GB SDHC card is the safest option for compatibility and stability.

5. Can my DSi run 3DS ROMs after installing Unlaunch?

No, the DSi cannot run 3DS ROMs. The DSi’s hardware is not powerful enough, and the game cards have a tab preventing insertion. 3DS games are exclusive to the 3DS family of consoles.

6. What can I do with a modded DSi?

With a modded DSi, you can run DS(i) game backups and ROM hacks from your SD card, launch any DSiWare from your SD card, and boot into DSiWare and homebrew applications by holding specific buttons when turning on your DSi.

7. How long does the DSi battery last?

The Nintendo DSi provides around 9 to 14 hours of playtime on the lowest brightness setting. The DSi XL offers 13 to 17 hours. These figures will vary depending on usage and screen brightness.

8. Do DS games look better on DSi?

DS games will not look objectively better on the DSi than on a DS or DS Lite. The DSi runs in DS mode when running DS games, using the same resolution. However, the DSi does have brighter screens which may improve the perceived visual experience.

9. Will a 3DS play DSi games?

Yes, a 3DS will play most Nintendo DS games. Exceptions are games that use the GBA Slot. Keep in mind that some Nintendo DSi games bought outside the PAL region may not be playable on a Nintendo 3DS from the PAL region.

10. What’s the best SD card for a DSi?

The best SD card for a DSi is a 32GB SDHC card from a reputable brand like SanDisk or Samsung. Ensure it’s formatted to FAT32.

11. How do I change the TWiLight Menu++ theme?

Go to TWiLight Menu++ settings, select “Theme”, then press “A” on the DSi theme. If your downloaded theme isn’t there, press “B”, then “Right” on the D-pad, and then “A” again.

12. What does hiyaCFW do?

hiyaCFW is a custom firmware that runs the Nintendo DSi firmware from the SD card rather than the internal NAND memory. It’s an alternative to Unlaunch, offering similar functionality.

13. Are DS games region-locked on DSi?

Older Nintendo DS and DS Lite software is region-free. However, there is a possibility of region encoding on future Nintendo DS software releases.

14. Can the DSi play GBA ROMs?

While the DSi doesn’t have a GBA cartridge slot, you can play GBA ROMs via GBArunner which comes pre-installed with TwilightMenu++.

15. What are DSiWare titles?

DSiWare are downloadable applications and games sold through the Nintendo DSi Shop. They are similar to WiiWare, but specifically made for the Nintendo DSi and DSi XL.

In conclusion, installing Unlaunch on your DSi involves a manageable risk that can be further minimized through careful preparation and following trusted guides. Backing up your NAND is a safety measure. With proper precautions, the benefits of Unlaunch, coupled with TWiLight Menu++, can greatly enhance your DSi experience.
