Space Shooter

im looking for a shooter game?there is a robot salamander that appears on the right screen that let's out enemies like a grey color that apperas on the right screen its a space shooter game with black background and there are enemies attacking while you shoot the big robot looking salamander can someone help me find the name of this game please? it's space shooter game and the back ground is black no blue clouds. The screen stops moving when you get to the boss he comes from underneath and stays on the right with space craft coming out?You start off with no auto fire in a small space ship
And a big robot follows you as the screen goes up the boss is a big salamander that comes on the side from the bottom right and he's long then the enemies come out from top down. It's not life force or gradius

I don't know your specific game, but I would suggest that you have a look here:

Or you invest 45 minutes into watching this:

Afterwards, you will have seen a screenshot of every NES and Famicom game, with the name on top. This should enable you to check all space shooters in existence.

(Unless it's a homebrew or some really obsure unlicensed non-Japanese Asian game. Then it might not be in the list.)
