It'd be cool if they retained the extremely wiiiiide aspect ratio of the 6-player cabinet as an option, as well as standard 16:9 and 4:3 viewing options. Then Rare or someone could release the Battletoads arcade game and do the same.
And yeah, the Alien vs. Predator arcade game would be tiiiiiiits.
Man, those old school arcade beat 'em ups are the best. Wish Turtles in Time were given a proper release (and a patch for the first game to bring back the original character selection screen).
