Virtua Fighter Model 1 polygons

I wonder what it all requires to extract polygons from even old games like Virtua Fighter Model 1? Despite making its notability increase thanks to having its arcade cabinet featured in a Smithsonian museum, become mentioned in Game Center CX, have two figmas and a Mii Fighter costume, most people nowadays cannot easily appreciate the nostalgia of this historical 1993 arcade game.

I don’t even see replicas of the Model 1 polygons in Miku Miku Dance (MMD) nor other polygonal tools. All this leads to my question: How on Earth do I at least see at least Model 1 Akira Yuki in MUGEN and MMD?
