NMO file extention

Okay, so when I was little I played this Backyardigans game called Super Spy Adventure. It got taken down, so I want to remake it. I did some research, and somebody got the files for it. It was made with 3dvia Virtools, which has been taken down. All the files (except for the sound effects and textures) are in either .NMO format or .VMO format. How can I convert these to work with Unity?

Hey there,
I might be too late, but I could send you a copy of virtools 5. Found in very deep in the web! xD
Contact me if you are interested!
