What is FND-OBJ? It's the model converter for MK4, turns .geo into .rax. (Which can be viewed with an program). Unfortunatelly it was made some time ago, back then XP/98 was typical system. The latter had DOS support. You may be able to run the stuff in XP, but there is a chance of corrupting things.
You will need DOSBox software, otherwise no cake.
Extract the files somewhere, but don't launch it yet. Create a folder called mk4 on C drive (or whatever you wish). Next, copy all the files from MK4STRIP to that folder. Okay, we're set!
Launch the program.
You should get this, but it isn't so hard as it looks. Type "mount c c:/mk4" and hit enter. That's good. Now switch to that directory by typing "C:". You may want to check the files in folder, to do so type "DIR"
Please note that this tutorial assures that you have the game already unpacked.
While you are here, type "GEO-ALL" and hit enter. Voila! The process should now work normally, but please be patient. It can take some time!
An error should appear on end, that's OK (related to moving things). You should not bother with that. It's still nice to have things organized, so copy all .rax from RAW folder to the VIEW folder.
Have fun!
