Original Playstation MKT (the one I have):



Greatest Hits:



I believe there may be others as well.

Due to the nature of your question, I'm guessing you didn't get the GH MKT...but don't be dismayed. The original isn't absolutely crap, just not UMK3 arcade-like. If you are used to UMK3, the air borne properites seem strange, especially when trying to juggle in the corner. And combos like Reptile's aaHp, Hp - dash + repeat combo don't always work out the way they should. However, due to the odd gravity, huge damage corner combos can be performed, which is fun.

I'm actually really surprised they improved the gameplay for the GH, Midway actually showing some initiative / effort - never!
