Install - Epicpkmn11/NTM GitHub Wiki

The install menu gives you a file browser of your SD card from which you can install titles.

NTM allows installing titles with the .nds, .dsi, .app, .ids, .srl, and .cia extensions. CIA files must be DSiWare, no 3DS applications. Along with your app file you can also have a TMD or save file, these must have the same name as the app file but with the extensions changed as follows:

  • public.sav => [rom name].pub
  • private.sav => [rom name].prv
  • banner.sav => [rom name].bnr
  • title.tmd => [rom name].tmd

Using a legitimate TMD file is required for the title to work without Unlaunch's launcher patches if installing to SysNAND. You can get a TMD from NUS using this Python script or from the ZIP found in the TMD files preservation thread on GBAtemp.

If you get an error that the title is not a DSi rom when installing then you will need to use a forwarder that will launch the actual file on the SD card. To install a forwarder to SysNAND simply install it to SDNAND (even if you don't have hiya) as that guide says, then in NTM back it up from SDNAND and restore the backup to SysNAND.

Once you select a title you will have the following options:

  • Install: Installs the title to the DSi Menu
  • Install as System Title: Patches the title to be a system title and installs to the DSi Menu
    • Only available on SDNAND
    • This will make the title not count toward the 1,024 block limit on DSiWare and cause the title to not show up in Data Management
  • Delete: Deletes the file from your SD card
  • Back: Returns to the file browser

If your title doesn't show up on the DSi Menu

There are a few reasons your title may not show up on the DSi Menu.

It's the wrong region and you don't have launcher patches

If your title is of a different region than your DSi then Unlaunch's launcher patches are required. Please install Unlaunch and ensure Unlaunch's launcher patches are enabled in TWiLight Menu++ settings. See dsi.cfw.guide's page for how to install Unlaunch with its launcher patches enabled.

Invalid title

If the DSi Menu decides that your title is invalid it will delete it. You can check if it was deleted by looking in the titles menu. To prevent the DSi Menu from deleting your title you can mark it is read-only in the titles menu before leaving NTM, however this will not make it show up on the DSi Menu so it will only be usable from Unlaunch.
