Dungeon is a dungeon game for Atari 2600.

Release notes from s0c7:

I still haven’t been able to replicate the problem on my system. However I would like to fix this if possible. All the varying hardware out there can make it difficult to have something universally compatible.

Try this version and let me know if it makes any difference on the TV that is giving you problems.
