Background

Freespace Vita Port Button Mapping (1, 2 and Demo):

For explaining the gamepad mapping for Freespace vita port.

Basic Controls:

TOUCHSCREEN             - Mouse Click for Menu Navigation
TRIANGLE                - Lock onto Ship in Reticle 
CIRCLE                  - Fire Secondary Weapon

	# 3. The start code that patches the relocation code.
