Sam Lantinga was given the copyrights for the source code to develop a Linux port of Maelstrom. In 1995 he ported the game to Linux and his Simple DirectMedia Layer (SDL) and released this version as free software. In addition to porting the software he also added features like a networked multiplayer mode, functions to capture screenshots, apply gamma correction and upload scores to a worldwide highscore list on the internet. He ported the THINK-C source codes to C++, which (at least at some point later) represents a superset to THINK C that is specialised in the development of Mac software. There are precompiled software packages available for easy installation of the software on Linux systems. In 2001 this lead to a native version for Apple's new operating system OS X.
