Nuon is a technology developed by VM Labs that adds features to a DVD player. In addition to viewing DVDs, one can play 3D video games and use enhanced DVD navigational tools such as zoom and smooth scanning of DVD playback.

Nuance emulates these old DVD game consoles.
The only commercial game I found that runs is Space Invaders.
There are some homebrew games that can be found at NUON-Dome that may or may not run.
