TypeHomebrew Loader

NDS MP is a GBAMP NDS Firmware Hack. An NDS aware firmware patch for the GBA Movie Player.

This is only for the GBAMP CF (Game Boy Advance Movie Player Compact Flash version). This will not work on the GBAMP SD (Game Boy Advance Movie Player Secure Digital version).

It is written in C this time (instead of ASM) and so able to add a number of features.


  • More compatible with CF cards, since it is based on my GBAMP CF driver.
  • No more need for _BOOT_MP.GBA to use the GBAMP default firmware.
  • Built in bootloader. Included in this zip is an example of how to use it.
  • Better maintainability. Since it is in C it is easier to read and change


  1. Flash GBAMP using one of the included files.
  2. Put a _BOOT_MP.NDS file on the root directory of the card.
  3. If using a bootloader, put other NDS files on the card.
  4. Start using a PassMe, WifiMe or FlashMe.

User guide

To use the normal firmware:

While turning on the DS, hold down Select.
Choose "Start GBA Game" from the menu.

To repair:

While flashing, press L+R+Select to run the repair utility.
Put Update.e19 in the root directory of your compact flash card, and update when asked.

Note: The manufacturers of the GBAMP SD have released an update similar to NDS MP. It is on the downloads section of the Movie Advance website.

Known issues

For Version 2.11:

More risk to GBAMP firmware. Since this is coded in C I had to remove chunks of the firmware to make it fit. Don't worry though, those chunks were repeats of other chunks anyway.

No ability to use _BOOT_MP.GBA anymore. That's still okay - just load it from the standard GBAMP firmware.



  • Nearly everything loads


  • Fixed SCUMMVM loaded from MoonShell


  • Made directory search case insensitive


  • Big speed up when clearing memory - should have listened to Tepples earlier
