Another great game that works for me without problems is Rouge. I am using TOS 2.06, which works with both the mouse and keyboard for this game. It's nicer than the classic version of rouge since there are actually pictures for the items/monsters as opposed to ASCII.




Rouge

In Rogue, the player assumes the typical role of an adventurer of early fantasy role-playing games. The game starts at the uppermost level of an unmapped dungeon with myriad monsters and treasure. The goal is to fight one's way to the bottom, retrieve the Amulet of Yendor, then ascend to the surface. Until the Amulet is retrieved, the player cannot return to earlier levels. Monsters in the levels become progressively more difficult to defeat. Rare is the adventurer who will again see the light of day.
