Okay, I have been trying to figure this out for a couple years and I know that someone here will know this
There was a helicopter game in the arcades maybe around 1986.... it had a trigger-grip joystick and IIRC there was some other odd feature to the "real" cabinet-
Anyways, it had boards that alternated between top-view and 3-rd person (from behind) 3-d
I think it was called "thunderblade" or "-cade" or some such thing... I want to at least DL an emulation of it if possible.....
