There's a button you can press for an explanation of features, which shows various scenes from the actual "game", here we have BttFIII with Marty lassoing numbers, haha.
the machine in its entirety, finally a place to put more of my UFO Catcher swag at the top! there's リセットさん from 動物の森 as well as Monkey D. Luffy with a pirate hat on (so incredibly hard to find, I spent 2 months finding him when I gave up and accidentally found him browsing on ebay one day) and a pillow of リーくん's head.
Here's the attract mode for the machine, complete with a polygon model of the DeLorean driving down the street. The monitor looks pretty high-def in person.
The flash didn't go off on this one so it's kinda hard to see, but there's Marty playing Johnny B Goode at the enchantment under the sea dance, lol.
If you're wondering about the girl in the bunny ears, DQIII let you pick the classes of your characters and you could pick a jester/fuckoff class which apparently looked like a casino drink wench.... or something.
