Older 3d Model imports

Hello. I am trying to remake an old game, and i found an exporter that seems to work fine. It is an os9 application, and its outputs are all outdated. The outputs are: Rotator (wireframe) AutoCAD DXF Alias|Wavefront Object NewTek Lightwave Object QuickDraw 3D Metafile and the ones that aren't much help are the Marathon Map Metafile and the Quake Map Source File. I'm pretty sure Unity wont take those two. If none of these work, does anybody know of any converters or updaters for these? Thanks.

Sorry, I've found my own problem. The exporter failed to put .obj. dont bother answering this.
