Searching for an NES Shoot 'em up

[Davy Jones]

A shmup with space ships, which I can't find anywhere. It's defintely for the NES and a horizontal shooter. I vaguely remember an ice world in stage 2 with destroyable blocks and a huge battleship on the later stages.

I've always thought it was R-Type, but then I found out that it was never ported to the NES. I played it in the 90s (PAL release), but I doubt that it was a pirated game.
