GodMode9i is a full access file browser for the Nintendo DS, Nintendo DSi, and Nintendo 3DS library of consoles. 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++
