# siglus_rs: reimplementing four visual game engines in Rust

> siglus_rs reimplements the UK2, AVG32, RealLive and SiglusEngine game engines in Rust, with its main focus on SiglusEngine. Launchers identify engines from game-directory formats and import games on supported platforms; the web launcher runs SiglusEngine, RealLive and AVG32, while UK2 runs on desktop, iOS and Android.

## Requirements & limits

- **Prerequisites:** Original game files are required in a game project directory.
- **Prerequisites:** Protected SiglusEngine resources require a 16-byte secondary key; the engine attempts to find one when it is absent or incorrect.
- **Limits:** UK2 is unavailable in the web launcher because its runtime needs threads.
- **License:** MPL-2.0 licence.
