I've seen some references to Dungeon Hack being a roguelike, here's a more modern version (of sorts).
Dungeon Strikes Back is a rewrite of a Dungeon Master / Chaos Strikes Back (games form the late 80's, early 90's) engine using the same graphics. It uses Lua scripting, and dungeons written for it are implemented using Lua as well.
Chaos Hack is a randomising dungeon.
