Q: Can I install homebrew on my DSi?
A: Yes! Follow dsi.cfw.guide to install HiyaCFW on any region or firmware version.
Q: Can I use homebrew without Flipnote Studio?
A: Unless you have a previously installed DSiWare exploit, you'll need to hardmod your DSi and install homebrew that way, however that requires soldering skills and a stable hand.
Q: So can I run ROMs on my DSi?
A: Yep, just install TWiLight Menu++. The guide above should allow you to install it to your Home Menu. TWiLight Menu++ allows you to run commercial DS roms, homebrew, and has various emulators preinstalled.
Q: Unlaunch freezes at MISMATCH IN FAT COPIES. What do I do?
A:This error is caused by twlnf. It has a critical bug that doesn’t properly update the entire NAND after modifying it. This causes certain homebrew (like the Unlaunch installer) to throw an error. Fortunately, this is fixable. Unfortunately, the method to fix it isn’t set in stone, and largely varies from system to system. Generally, deleting any DSiWare installed via twlnf in the past does the job, but make sure you have another homebrew entrypoint available if you delete an entrypoint. It has also been reported that moving all DSiWare to the SD card and back to the system can help in some cases.
Q: Can I install HiyaCFW without Flipnote Studio?
A: No, you will need a hardmod to install HiyaCFW. Follow Gadorach’s hardmodding guide to hardmod your DSi. Previous soldering experience is required.
Q: Can I use an SD card higher than 2GB with HiyaCFW yet?
A: Yes, using TWiLight Menu++. See the Replacing System Menu with TWiLight Menu++ page for more information. Low-level “full” formatting your SD card with a tool like GUIFormat can help as well, but this will not get you around the DSi Menu’s block limit, whereas TWiLight Menu++ does.
Q: Why don’t I see TWiLight Menu++?
A: You’re in SysNAND instead of the SDNAND. The HiyaCFW Helper isn’t applying the CFW’s patches properly, so please wait for a fix in the helper.
Q: Is there a safe way to remove Unlaunch?
A: Yes, Unlaunch v1.5 and higher’s installer can uninstall Unlaunch. Keep in mind that this may result in an irrecoverable brick if you have installed any arbitrary DSiWare to your system NAND, or have otherwise messed with system files.
Q: fuse-3ds fails to launch, or to mount my NAND backup!
A: This can happen for several reasons, but the most common is that your PC is missing Windows Updates that are required for the program to run.
If fuse-3ds shows nothing but a black command prompt screen, just wait a while longer- the program can be slow to start.
If fuse-3ds shows the following error at startup:
The procedure entry point ucrtbase.terminate could not be located in the dynamic link library api-ms-win-crt-runtime-l1-1-0.dll.
You are missing the following Windows Update: https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows
If fuse-3ds fails to mount with the error message:
Cannot create WinFsp-FUSE file system: unspecified error.
You are missing the following Windows Update: https://technet.microsoft.com/en-us/library/security/3033929.aspx
Both of these updates are several years old. If you’re missing them, it is highly recommended that you enable Windows Update on your machine in order to keep your system updated and secure, and to avoid issues like this in the future.
