Contra III: The Alien Wars uses slow memory banks (it's a SlowROM game), this patch moves all important banks to the fast location.
Now the game has way less slowdown.
This is a good solution for cheap flashcarts users.
Version 1.1: Fixed difficulty level selection glitch. More optimizations were made.
