Battle Shark 1CC No Damage

This is a really fun game. It is a crosshair shooter where you are the gunner of the submarine Battle Shark and was released in the arcades by Taito in 1989.
My goal was just to get a 1CC, but I somehow managed to pull off a no damage playthrough, as well. I definitely got lucky at least twice when I just barely managed to shoot down a couple of torpedoes that were about to hit, but other than my bad accuracy it went fairly smoothly.
Played on WolfMAME 0.175 using the Japan, Joystick version. As far as I know, the only differences between regional versions are the text and analog controls.
