From GameBrew - a wiki dedicated to Video Game Homebrew.
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 (r4ultra.com)).
- Browse files on the SD Card when running GM9i from any DS-mode flashcard (Requires a DS game launcher with SD access enabled).
Supported flashcards, if being ran off the SD card or as a CIA:
- Acekard 2(i)
- R4 Ultra (r4ultra.com)
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.
- Fixed an overlooked bug where dumping a trimmed ROM would show Failed to dump the ROM. when done.
- (@unresolvedsymbol) Added .nds ROM booting with nds-bootstrap. It is done by selecting Bootstrap file after selecting a .nds file.
- Filename of the GBA or NDS ROM is now shown when dumping, so you'll know what to look for.
- (@unresolvedsymbol and @Epicpkmn11) Separate the selection and the clipboard like GM9.
- Added selecting while holding L.
- The first 5 paths that will be deleted, will be printed on the bottom screen.
- (@urmum-69) The free space on each drive in the root menu is now shown!
- GitHub page link has been updated.
- The regular .nds file has been renamed to .dsi.
- A new .nds file has been added for flashcard compatibility.
- (@RocketRobz and @Epicpkmn11) Fixed some known issues when dumping ROMs.
- (@Epicpkmn11) Fixed getting EEPROM size when the first is all 0.

v2.4.0 SD x NTR release
- SD access is now possible in DS mode. This means you can now copy/move files between the console's SD card, and the flashcard, no matter which one it is. Requires a DS game launcher that supports SD access, such as TWiLight Menu++. (Set SLOT1_ENABLESD to 1 in sd:/_nds/TWiLightMenu/settings.ini)
- The SDMMC code improved by profi200, is now in use.
- Before the drive menu is shown, you can now hold X to skip NAND mounting, in case if you're using GM9i with hiyaCFW.
- Console ID is now read from the AES ports. This allows browsing the DSi NAND with just DSiWarehax (such as sudokuhax, Flipnote Lenny, Memory Pit, etc).
- Added message under Y - Held.
- Fixed files/folders in folders not being copied to /gm9i/out/, when pressing R+A.
- FAT image (.img) files can now be mounted.
- NitroFS or the FAT image can now be unmounted by pressing R+X.
- 3DS console is now found by checking the NAND.
- Improved DS(i) ROM dump speed to run twice as fast.
- You no longer need to manually open the SD card before unmounting.
- GM9i can now start successfully without an SD card.
v2.2.0 Goodbye twlnf! (Valentine's Day release)
- NAND browsing is finally added. The code is from twlnf (by JimmyZ), but for safety reasons, the NAND write code has been removed, so you won't have to worry about locking out Unlaunch installs/updates, or bricking your console. This makes GodMode9i a safe alternative to twlnf for NAND browsing. NOTE: This feature is only available for DSi consoles, and may not work without Unlaunch.
- Added direct access for Acekard 2i with Deep Labyrinth banner.
- Added NitroFS mounting for other DS(i) ROM filetypes.
v2.1.1 DS-mode bug fix release
- Fixed green smiley faces appearing, instead of a green border.
- Fixed DS game dumping being shown on Slot-1 flashcards.
- The GUI now looks closer to the original GM9, with the top text now placed behind a green line, and unhighlighted folders now tinted blue.
- 2 RAM drives are now available. One is shown for both DSi and 3DS (9MB), and the other is only shown for 3DS (16MB).
- The size of the highlighted drive is now shown.
- File/folder attributes can now be changed.
- Time text is no longer cleared, except for when dumping GBA ROMs.
- Directory options (R+A) are now shown.
- You can now press R+A while any .. dir is highlighted, to go back to the drive menu.
- Fixed some TWL ROM dumps not containing the complete header. It is unknown if the bug with missing TWL binaries is fixed.
- (@Epicpkmn11) Fixed file browsing being super flickery.
- When renaming a file/folder or creating a folder, unsupported characters are now blanked out, to prevent deletion.
- DS(i) carts can now be dumped to Slot-2 flashcards as well (Untested).
- TWL ROMs are now properly dumped. It is recommended to update to this version, and redump, if you dumped them with v2.0.0.
