C-Dogs SDL is a port of the old DOS arcade game C-Dogs to modern operating systems. C-Dogs is an arcade shoot-em-up which lets players work alone or co-operativly during missions, and against each other in the "dogfight" deathmatch mode. The original DOS version of C-Dogs came with several built in missions and dogfight maps, and this version is no exception. The author of the DOS version of C-Dogs is Ronny Wester.
Chocolate Doom is a Doom source port which aims to behave as closely as possible to the original DOS Doom executables ("Vanilla Doom"). It aims to be compatible with DOS Doom demos, configuration files, savegames, and bugs. As far as possible, it provides the same features that are available in the DOS version, along with the same "feel" of the original game.
GLoid is a 3D block game inspired by Arkanoid. It was originally written as an SDL and OpenGL exercise, but has developed into a full-featured, highly playable game with refined graphics and sound effects. It runs equally well on Windows, Linux, and Mac OS X, and has minimal hardware requirements.
