Turrican for the Genesis is a okay port, but have 2 big problems:
The fantastic Soundtrack was translated very bad.
When you collide with an enemy, the health gauge is drained 4 times faster than the original and this make the game almost unplayable!
This patch improves the color palettes to look the most accurate possible to the original and fix the problem with the health gauge*. Now is possible to have fun with this version!
