Quoted from LilRocky:Dragon's Lair/Space Ace are coming, with art sets for both styles, but I'm curious on the emulation as well. New Wave Toys did an awesome job on their mini-cade package, so I'm hoping A1Up's follows the same emulation. The one thing I hope A1Up changes is their idea for needing to dock your phone above the screen to emulate the LED scoring.
As for Tron, I added myself to the pre-order craziness. My only other two must-buys are Dragon's Lair and Track & Field.
Dragon's Lair and Track & Field are 2 of my favorites. I own them both.
