Can flickering objects from the sketchup warehouse be fixed?

I have found this guy named Gozer that has recreated 540 real life arcade machines and I want to make the worlds biggest arcade in NL2 ever using his machines.

The textures flicker on 3 out of the first five that I downloaded. I believe it is from a z fighting issue. This is not a good sign at all for all 540 machines that I want to have in this arcade.

How can I fix that so that I can have all 540 of his machines in a giant building in my Worlds Biggest Arcade NL2 park.

Just out of curiosity, but what are your favorite music arcade games?
