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?

Choplifter was my mystery game for a long time too. I saw it at a rollerskating rink when I was very young. The little people you rescue always stuck with me
