Crus'n USA Exotica (arcade game) Easter Egg - Find Hidden Credits (Creators Names Not Free Plays)

I found this out last night at a bowling alley arcade.
When you see the game, Crus'n USA exotica (it can only be in the arcade, not the computer game.), on the left side will be 3 buttons. Lo Cam and Hi. Is you press and hold all three buttons at the same time, a picture with all the creators will appear along with a list of credits.

Pretty pointless but i think its cool.
