Great game. The arcade version from 1988 was Capcom's very first game on their then brand new CPS1 board. The same hardware that powered Daimakaimura (Ghouls 'N Ghosts), Strider, Final Fight, UN Squadron and Street Fighter II among others.
Spent quite a few hours on that game when I was a kid which is why the stupid shop music haunted me.
We had a huge library of JP PCE games and great memories having parties with them, like 5 player bomberman (before Saturn 10 player came along) and the YS games. Back then those visuals with voice were mindblowing.
