I cannot remember the name of this arcade game back in the 90s or late 80s. It was an horizontal shooter were you controlled an old airplane, kind of a WW1 biplane with a propeller. You are in an island full of dinosaurs and you shoot at them. You have some kind of orb as a power-up that you can move around your plane like in R-Type. Does it ring the bell to any of you?

Well no

I'm looking for an answer to the same question. Yes, I know what you're talking about.
