Wh16 has yet again released another SDL port to the Dreamcast, this time its called Commander Tux Duel, heres some info about this game:

Commander Tux Duel by Andr-Schnabel. Another nice game. This one supports 2 players (keyboard or controller) and is basically a Mario Bros. clone. All you have to do is jump on each other’s head. The upper and lower display are off the screen on my television

Download from Storm Studios
