Installing DSiWare

If you need help, ask the NDS(i)Brew Scene or the Nintendo Homebrew Discord servers.

You must have Unlaunch and HiyaCFW installed before proceeding.

This method will install your 3DS DSiWare dumps to your DSi console’s home menu. This will convert your 3DS DSiWare dumps to an installable format using a tool called maketmd.



  1. Copy the contents of the maketmd .zip file to a folder on your PC
  2. Open the dumped folder on your PC containing your DSiWare
  3. Navigate to content
  4. Delete the cmd folder, and the .tmd file
  5. Delete any .ctx files if they exist
  6. Drag and drop the .app file onto the maketmd program
    • You will see a new file named title.tmd be created
  7. Copy the DSiWare folder to the /title/00030004 folder on your DSi’s SD card
    • If your System Menu has been replaced with TWiLight Menu++, you can place the .app file anywhere on the SD card, and just launch it. In this case, you’re done!
  8. Power on your DSi, and “unwrap” the new DSiWare
    • If you boot to an “error has occured” screen, you have exceeded the amount of allowed DSiWare blocks on your system
    • TWiLight Menu++ can get around this limitation, see Replacing the System Menu with TWiLight Menu++ for more information
