Road Runner was released in July 1986 (even if title screen says 1985).
Road Runner, as with all the Atari System 1 games, was arguably one of the most distracting games in the arcade. If not setup properly, the Road Runner game would play all the background music during the intro cut scenes. The Atari System 1 speaker system had a great acoustic arrangement. Players would be immersed in a sea of sound allowing them to really get into the game play. Unfortunately for others, they could hear the same thing on the other side of the room!
Some Road Runner units were produced (757 exactly) from the factory. Most arcade owners purchased the conversion kit which was marketed and readily available from Atari at a lower price ($695) than a new system ($1895). An Atari System 1 cabinet could be converted into a different game (only other Atari System 1 games) in a day.
A graphically enhanced version of this game (Apparently running on "Beat Head
" hardware) was planned, where each stage would have a Road Runner cartoon scene as an intermission, spooled from a laserdisc. However, although a master was produced (now in the hands of a private collector of Atari prototypes), no discs were ever pressed and it is likely that no ROMs were ever burned.
