Thanks for converting this.
When run straight as zipped, the game crashes when some enemies become activated. Might have to do with the sound clips used?
If I recall, this may have also been an issue with the original version as that too was very unstable.
This is a proper AlephOne port of the old Erodrome scenario for Marathon Infinity.
Should you encounter any more problems that were not present in the original version please post a comment and I will look into it.
PS: Be warned that Erodrome contains quite a bit of nudity in some of the later levels of the game.
