NDS/Converting NDS to DS GBA

From Dev-Scene

< NDS

To convert a .NDS file into a .DS.GBA file, there are several methods. You will have to try them to see which one works in your particular situation.

  1. Simply rename it. Many .NDS files already contain necessary loaders. This may not work on older homebrew, or on certain flash carts
  2. Use DSBUILD. This is included in DevKitArm. In windows, simply drag & drop the .nds file onto dsbuild.exe, and it will create a .ds.gba file
  3. Prepend a loader, such as ndsmall.bin or DefaultLoader (aka loader.bin, used by dsbuild.exe)
    • In windows: copy /b ndsmall.bin+game.nds game.ds.gba
    • In linux/mac os x: cat ndsmall.bin game.nds > game.ds.gba
