Rise of the Triad DS is a port of “Rise of the Triad” for the Nintendo DS.

Changes:

Sound effects are now fully supported.
Music is now supported, with caveats. ROTTDS cannot (currently) play the game’s music natively; however you can extract the music files from the game, convert them to ADPCM on your PC, and place the resulting files in your /rott/ directory, and ROTTDS will play them. I’m providing a music package containing the shareware music in ADPCM format. See the README.NDS file for more info.
