I doubt you can. To remove the perspective the scene would have to be rendered as a projection onto a subsection of a plane, but the camera projects out from a point and renders to a cross-section of the view field.

Have a look at this part of the platform game tutorial in the newsletter:

http://www.thegamecreators.com/data/newsletter/newsletter_issue_67.html

Search for the word "perspective". It suggests a way to remove perspective from 3D objects by setting a very large camera distance and a big field of view. It's for DB Pro but the same trick may work for Dark GDK as well.

Wow, that actually works pretty well. Never would've thought of that.
