the only two ROMs I can find are:
* Smurfs, The (E) (M4) (v1.0).gb
* Smurfs, The (UE) (M3) (v1.1).gb
so it was probably released in Europe first.
I found a (UE) (M4) (v1.0) [!] version.
That would have been my used ROM but it wasn't obtainable.
Its a run on a smurfs game though, not many people are going to care that much about it just on the title.
EDIT: It's actually something like this, isn't it?

The game has something to do with a cartoon character so it is rejected right away without even seeing it...
I give some information about the game now if that helps...:
In this game which has 12 levels plus 3 boss fights I play on the hardest difficulty. It's a jump 'n run in which you must run to the exit. But there are several enemies and hindrances.
When you get hit you fall a bit backwards.
So I often turned around in front of enemies to save time instead of waiting for a moment to defeat the enemy or to jump above him.
