OpenTS builds on years of reconstruction, engineering, testing, and community support.
OpenTS builds on prior research by Command & Conquer community members, including CCHyper, whose work on the Command & Conquer Remastered Collection and the 2025 The Ultimate Collection releases helped bring about the Electronic Arts source code releases below.
- Kerbiter — advice on preparing the public release
Electronic Arts released the source of related Command & Conquer titles under the GPL, and OpenTS is built from that material:
- Command & Conquer Remastered Collection
- Command & Conquer Red Alert
- Command & Conquer Tiberian Dawn
- Command & Conquer Renegade
- Command & Conquer Generals and Zero Hour
The additional GPL Section 7 terms covering that material are in LICENSE.md.
Years of community fixes for the original executable live in ts-patches, and Vinifera carries that work into a source-level engine extension. Fixes OpenTS ports from either credit their authors by name when possible in the manual's change records.
