Help finding an old PSOne game!

Hi guys. Sorry to bother but I was wondering if someone could help me. Back in the day me and my cousing used to play a demo for a flying ship game so many hours that I can't even imagine. Anyway now with the ps classic and the love for old games coming back to me I'm wondering if someone knows the game. The game consisted in the following: 2d game where you fly a triangular shaped ship where the objective was to destroy the enemy ship (1v1) and you could also crash against platforms. The tip of the ship shot some tiny white bullets. Also like I said the game was in one of those magazine demos. Anyone can help? :)
