MARS 2.2 was released in March 2006 with additional bug fixes and implemented command line options (run MARS from command line with h option for command line help). This also coincides with our SIGCSE 2006 paper "MARS: An Education-Oriented MIPS Assembly Language Simulator".

MARS 2.1 was released in October 2005 with some bug fixes.

MARS 2.0 was released in September 2005. It incorporated significant modifications to both the GUI and the assembler, floating point registers and instructions most notably.

MARS 1.0 was released in January 2005 and publicized during a poster presentation at SIGCSE 2005.

Dr. Ken Vollmar initiated MARS development in 2002 at Missouri State University. In 2003, Dr. Pete Sanderson of Otterbein College and his student Jason Bumgarner continued implementation. Sanderson implemented the assembler and simulator that summer, and the basic GUI the following summer, 2004.

The development of Releases 3.1 and 3.2 in 2006 and 4.0 in 2010 were supported by the Otterbein College sabbatical leave program. The development of Release 3.7 during summer 2009 was supported by a SIGCSE Special Projects Grant.
