Ultimate Mortal Kombat 3 Rev 2.1 (Arcade)

hehe ive been playing this with my MAME program it beats paying a £1 to play it at the local arcade and anyway ive managed to get 2 of the ultimate kombat kodes into it to unlock Mileena and Ermac just got classic sub-zero to unlock now, ive got the kode for the unlock just have to get it in within the 10 seconds time limit now lol

Im a Mortal Kombat Geek! piccy below... As you can see where the silver dragon square is that is a hidden character thats locked (classic sub-zero) the 2 characters next to him to the left were also hidden characters that i have unlocked each with a "ultimate kombat kode"
