3-D Dinosaur Adventure Art-A-Saurus help

[Hanson93]

I downloaded 3-D Dinosaur Adventure Anniversary Edition just yesterday and while the main game works just fine, there's no option to launch Art-A-Saurus. I've been trying to screw around with a new dosbox.conf to autoexec on launch, but the game either 1) shows me an "Error loading bitmap" message and then autoruns 3DDA, or 2) just crashes outright. I have a very rudimentary understanding of how to mount in DOSbox, so if there's something I'm doing wrong, I would appreciate any help.
