Okay I'm trying to figure the name of a game that I played as a child. It was like a space ship but you weren't in space and you flew around destroying other ships.... Some other clues. There were turrents or cannons mounted on the side of the mountains and I remember that I had like cluster missiles. Thats It and the cover of the case had a plane/ship flying towards you!

Novastorm?

Was there even a PS1 version of Novastorm?

No, I also remember that the ship was yellow

YES!!!!!! Thank you!=) I love this game.

You're welcome.
