 Team member Lucas Davis compiled the development tools and documentation for Anachronox and released them in August 2001. Four bug-fixing patches exist for Anachronox. Ion Storm created the first (1.01), which fixed the Windows 2000 buffer overrun crash and implemented other improvements such as taxi-cabs between distant points and enhanced save game functionality. Ion Storm released the first patch (1.01) on July 2, 2001. Joey Liaw set up a GeoCities website for reporting bugs and technical information after the game's release, and worked on a new patch in his spare time. The second patch (1.02, or build 44) was released in May 2003 and overhauls the save-game system and provides other important stability fixes. The third and fourth patches — 1.02 (build 45), released September 2003, and 1.02 (build 46), released April 2004 — are fan-made unofficial patches and fix most of the remaining bugs. Fans have translated the game into German and released a conversion patch. Level designer Rich Carlson released a scrapped secret level for Anachronox in February 2004 after finding it on an old floppy disk.
