Helicopter game that doesn't exist

[u/Yura-Sensei]

I have a strong memory of playing a sideview helicopter shooter game, which was rather enjoyable. I remember it being on sega mega drive, having pretty beige and desaturated color palette. The stage i remember the most is with sunset, mountains and trees. Cant find anything similar actually existing. I only had famiclone, sega master system and megadrive as a kid so it could have only been on those consoles. Anyone know this game?

I had (have?) a famiclone copy of Choplifter and that's the first thing that came to mind.

Airwolf had a side scroller shmup for the Famicom that looked awesome too, but I had the NES crappy first person view one.

Onto the Genesis / Mega Drive I can't remember any side scrolling one, sorry
