Type in "debugup" during play to get debug mode. You will see coordinates appear in the top right hand corner and Dinos will ignore you unless you shoot them.
Keys to use while in debug mode:
Cheat Code - Granted Wish
CTRL - Run Faster
SHIFT+S - Slow Motion
CTRL+N - Long Jumps
SHIFT+T - Show Frame Rate
TAB - Full Map
SHIFT + L - Unlimited Ammo/Fly mode
For the Fly mode cheat you need to use the mouse and the CTRL-key to fly.
File Hack for all hunts, animals and weapons
Open the "_RES" file located in the "Huntdat" folder of the game directory on your hard drive. The "_RES" file contains specs for weapons, characters and prices. Changing the values in the "_RES" file will change the values in the game.
the following weapons values can be changed:
power: changing this value to 20 will kill anything with one shot.
rate: the higher the value the faster the weapon will repeat fire.
shots: number of shots or ammo
reload: some weapons have this option and a higher value allows for faster reloading
I didn't see any need to alter the values of the characters but these could be played with as well to control aggresiveness, health and other things listed in the "_RES" file.
Prices for everything can be lowered to a value of 10 and the start value raised to what ever you like, I used 500 so that everything could be purchased right away. One thing I noticed is that purchasing multiple weapons in the selection stage doesn't give you multiple weapons during the hunt.
