NDSForwarder is a homebrew application that can create NDS forwarders and install them to the home screen of the 3DS.


  • Custom dsiware banners.
  • Custom Icons.
  • Auto Random TID. This allows separate forwarders for romhacks that dont change TIDs.
  • Custom Title. If you dont have a custom banner, or want one but need a different Title, check the box.
  • Install all in folder. You can install forwarders for all nds files in any given folder.


This homebrew requires full CFW via Rosalina (b9s+luma3ds).

The easiest method of installation will be to download it from Universal Updater. This will include all required files/forwarder pack for the SD card (see tutorial).

To install manually:

  • You also need the nds-bootstrap forwarder pack, of which the forwarders created with this app work in conjunction with.
  • Extract the forwarder pack, copy the _nds folder from the for SD card root folder to the SD card.
  • Copy ndsForwarder.3dsx to the /3ds/ folder of your SD card.

Notes from developer:

It is recommended to use full dumps (not trimmed ones) as the current dumping tools on both 3DS and DSi seem to have issues dumping trimmed files.

Read more about it on the GBATemp page (NDSForwarder takes the place of the Forwarder3-DS java app listed on this tutorial).
