: Now I'm going to go out on a limb by assuming that you probalby use a PC.
: Converting these games for use on a PC is not a trivial effort, and we
: can't do much other than to help you because of copyright limitations.
: However, there is a conversion of the original Marathon game for Aleph One
: SDL (M1A1 SDL), which will run on just about any PC. Best of all, it's
: completely free. Head over to the Marathon Open Source Page to download
: the latest Windows build. Unfortunately, the link on this page to M1A1
: seems to be broken, but you can pick up a copy from the Lh'owon Ar'kives
: at Fireball and, while you're at it, be sure to pick up the M1A1 for SDL
: Script Update . This should be enough to get you started and for you to
: decide if you like Marathon enough to go to the trouble of converting the
: other scenarios to work on your PC.
Me Myself & I, Steve pretty much nailed it. But I should add if you are going to use Aleph One for Windows, there is a great tutorial page by a guy who struggled with it and wrote down the steps to install it and to get some Marathon maps to play with it. Click on the link below.
