Need a coder capable of hacking a Windwos game exe using HEX editor.

Want to hack a Windows game exe in order to change some capabilities currently not available. - Add a control to the player so it can move around the weapon cameras and lock the desired target (currently automated) - Add a keyboard entry that activates a green filter to simulate Night Vision Googles. - Add a keyboard entry that refuels the aircraft during flight, something like reversing the fuel flow.
