Look in Wonderland>>makeActorFrom: which is the metod you will
have to change to be able to read in all the alice files, I think.
The alice file spec. has probably changed?

VRML and 3DS are supported. There should be quite a few 3d fileformat
converters for various platforms out there.

VRML have some primitive objects defined allready in the image.
You could also make objects in the same fashion as B3DBox.
