kayvenm has updated his port of Descent to the Nintendo DS. You will require some files from the original Descent, which are not included in the binary due to copyright reasons.

Notes :

You need the 1.5 data files (descent.hog and descent.pig). Shareware files wont work since they never did a 1.5 patch and the lastest shareware version is 1.4a… Sound is in but still a little glitchy. No music. No network. Start is enter, select is escape (for menu navigation). Touch the weapon on the bottom screen to select it.
