M1A1 was a port of Marathon to Aleph One released in 2001 and updated in 2002 before Aleph One was able to use the original Marathon data files.
Today, Aleph One is able to play the original Marathon 1 which can be found at lhowon.org. Downloads for M1A1 will not work with Marathon 1. See the Marathon 1 scenario page for compatible files.
An archive of the the original M1A1 Project homepage can be found here.. Downloads can be found on the Fileball Archive.
