Porting the game from Linux to Windows was easy, as it used cross-platform tools such as OpenGL and Simple DirectMedia Layer.[6] A major update including those improvements, version 0.60, was freely uploaded to SourceForge for both Linux and Windows on October 2, 2000.[9] A minor patch for that release was often included in most Linux distributions,[3]: 191 and a port for Macintosh was released in November 21, 2000.[4]
