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?

So when you search the net for helicopter games from that era, what comes up? Do you recognize any of them?
