So this track is for Air Duel (Japan) on M72 hardware. The MAME team added Air Duel (World) on M72 hardware in MAME 0.222 moving the Air Duel (Japan) on M72 hardware to ROM set name airdueljm72. You guys played the World version, not Japan, unfortunately.

Are you going to ask Twin Galaxies members to vote NO
