Went back and beat Fester's Quest. I had to cheese the final boss by standing to the far right and shooting missiles, though. I can't find a video online of anyone beating it "fair and square"...I just wanted to see someone actually do it.
I checked out an arcade bar here in KC called Up Down...it's awesome!! It's got a good mix of 80s and 90s machines...I played Donkey Kong, Double Dragon, Sunset Riders, Killer Instinct 2, Mortal Kombat 2, Wrestlefest, Street Fighter II CE (actually got some challengers on this one), Superman, Arkanoid, Ivan Ironman Stewart's Off-Road, Turtles in Time, and the South Park pinball game.
Good to see a resurgence of retro arcades here. There's a place called Square Pizza down the street from me that has about a dozen machines, too, and another arcade bar in the metro called Tapcade. I hope the excitement for these places doesn't die down any time soon.
