Thanks, this really helped.

Two questions though:

-How do we get the music/soundtrack to play?

-Is it possible to get the CGI cutscenes to show?

When I try to play Aliens, in Dos Box it says that " You must have the Alien Trilogy CD in the drive. " and I do have the CD in my D: drive. What do I do?
