TypeFile Browsers

GodMode9i is a full access file browser for the Nintendo DS, Nintendo DSi, and Nintendo 3DS's TWL_FIRM. It works on any console that has either a flashcard or Custom Firmware.


  • Dump GameBoy Advance cartridges on the original Nintendo DS and Nintendo DS Lite consoles.
  • Dump Nintendo DS/DSi cartridges on Nintendo DSi and Nintendo 3DS consoles (if GodMode9i is ran on the console SD card).
  • Copy, move, delete, rename files/folders and create folders.
  • Mount the NitroFS of .nds files.
  • Browse files on supported flashcards when running GM9i from the NAND or SD Card (AceKard 2(i) & R4 Ultra (
  • Browse files on the SD Card when running GM9i from any DS-mode flashcard (Requires a DS game launcher with SD access enabled).

User guide

Supported flashcards, if being ran off the SD card or as a CIA:

  • Acekard 2(i)
  • R4 Ultra (

To get around this limit, run GM9i from the flashcard itself, with SD access enabled in your DS game launcher, such as TWiLight Menu++.

  • If you have a NDS or DS lite, you can run this on a flashcard using either TWiLight Menu++ or nds-hb-menu.
  • If you have a DSi, you can use TWiLight Menu++ to run this from the SD card.
  • If you have a 3DS or 2DS, you can either use TWiLight Menu++ to run this from the SD card, or just install the CIA, and launch it from the 3DS HOME Menu.

Most flashcards will see GodMode9i as a retail game, so you may need to launch it from HBMenu or TWiLight Menu++.

Custom Fonts

  • GodMode9i uses the same FRF font files as GodMode9.
  • To create an FRF font use GodMode9's Python script or you can find some in the resources/fonts folder in the repository page.
  • When loading GodMode9i will try to load /gm9i/font.frf on your SD card and if that fails will load the default font.
  • To change the default font when building GodMode9i, replace data/font_default.frf with your font.
