Please help me finding the name of this game

It was a Game Boy game, beat 'em up genre. You control a guy who has to save his girlfriend, beating a lot of enemies with karate kicks. The music was very catchy and high pitched. It had boss battles, I don't remember if it was in every stage though. I remember two stages, at the beginning in a cargo train and the last one in a skyscrapper construction. The enemies and bosses were all humans, no bosses or supernatural things. Finally, it had a feeling of a classic japanese or chinese action movie.

Please I want to know what I was playing long ago...

Yes, sounds like Double Dragon to me too.

double dragon i think

[QUOTE="roboccs"]I had no idea Double Dragon ever came out for gameboy... but that was my first guess when I read the description. The NES version was amazing!!! Never beat it though. Got to the final 2 bosses. Los9090

I've got it. I'm rubbish at it :D

oh yes the GB had double dragon on it

After watching videos on Youtube... no, that's not the game. The one I'm talking about had worse graphics (DD had nice graphics for a GB game).

Probably it was just a random no name game becaue I've tried searching all beat em ups and can't find anything...

No that wasn't either... I think it was a japanese copy and probably one of the early GB titles because those games look better from what I remember.
