yup that is it. thank you. still learning . and again thanks for the heads up on the joystick. just a beginning

I was in college in Fairbanks, AK .. when I first saw Killer Instinct.. failed and skipped a lot of classes for that game  and never completed college. I don't blame it all on the game but it didn't help :p

loved this game, 43 now, installed mame and bought a x arcade controller to get me started.

its kind of like asteroids as your a small ship shooting at asteroids, but they don't blow up they shake first and release gems which you need to collect. bad guy ships will also collect them to build this big head (boss) that will come after you when complete.

please help! 

love mame and classic arcade, will most likely be building a cabinet. but need some help remembering some of the old ones I played as a kid.
