Map Theif [sic] is a map stealer. It allows users to save the map they played on last to a separate map file. The first public version was written by Annelid in 2002 and released on 2002-08-14.
Map Theif was made obsolete for Worms Armageddon players on 2004-02-20 by version 184.108.40.206 of Worms Armageddon's Beta update, written by Deadcode. This update allowed players to right-click on a Replay file in Explorer and click "Extract Map" to extract the map file used in the replay.
How it works
WA and WWP store their most-recently-used maps in a file called current.thm, which is located in the %installpath%\Data directory. Map Theif reads current.thm, copies everything from 0x04 onward into a new file, and gives it a file extension based on what the image format seems to be.
