The Past Ain't What It Used To Be...
The first Command & Conquer received its last official update on the 21st of June, 1996. Since then, the game has been ported to Windows (as "Gold" version), and re-released in the big "The First Decade" collection pack, but has never received any more bug fixes.
The C&C Gold Patch 1.06 project aims at bringing this classic into the new millennium, by fixing the old bugs, supporting higher resolutions, and adding new modding and mapping possibilities. It also contains an addon-based language system, allowing anyone to create translation packs for the game.
