List of game engine recreations

Game engine recreation is a denomination for game engines that are clones of the original game engine binary that came with the video games. The main motivation behind such a project is the wish to play the game on other operating systems than those supported by the original game engine.

In most cases a clone is made by reverse engineering the original executable, but occasionally, as was the case with some of the engines in ScummVM, the original developers have helped the projects by supplying the original source code—those are so-called source ports.

Exult replaces Ultima VII's engine so that the game can be played on other operating systems and platforms. It also expands the graphics capabilities of the game and adds features not present under the original engine. (A legal copy of Ultima VII is required in order to use Exult.) Lord British (aka Richard Garriott) himself, the creator of the entire Ultima franchise, has given the Exult team his unofficial blessing.
