mostly AI based but the developer CommonLoon102 spend most of the time (some month) to get the port as near as possible to the original game (many many test-cases and automatic replay-comparison over serveral thousand files), optional with original grafix and physcis bugs - and a bunch of enhancements
runs on DOS, Windows, Linux, BSD, Web-Browser and serveral other platforms
