Dissent scenario by Thomas Reed. Modified for Aleph One by Mark (no last name).
from the readme:
Users must have Aleph One 0.16 or higher. "Marathon Dissent.bin" in the read me folder can be decoded (.bin file) and used with the the decoded (.bin) Image and Map files in classic. The look and feel of the game should be the same. The mml scripts are for text strings and opengl code.
