You can fire weapons out into the rest of the Carrington Institute using the Farsight XR20, but another way to explore the stage in training mode is to use the crate from the cargo area to jam open the doors to the firing range.
Then fire off a tele-guided Slayer round into the main foyer of the Institute. Since the missile has no fuel, you can move it anywhere the heck you want to where there are no closed doors.
Here's a handy little trick if you're having problems beating all the weapons challenges in the firing range. Go into the Carrington Institute firing range and access the Laptop Gun challenge (for any medal). When the training session begins hold down the B button so the gun switches over to the secondary weapon mode (sentry gun). Hit Z to deploy the sentry gun -- but as soon as you hit Z hit the START button. Select "abort", then hit START again as soon as the screen starts to fade. You should now be back at the weapon challenges list. You can now pick any challenge you haven't completed and commence the training. If done properly, the sentry gun should still be deployed and will start firing at the targets and beat most of the challenges for you. Note that there are some challenges where this trick doesn't work, such as the RCP-120.

Having trouble beating some of the tougher challenges in PD's Combat Simulator mode? Here's little loophole that lets you easily beat all the challenges without any problems. All you need to execute this trick are two controllers and a memory slot to save your game.
Using the first controller, select Advanced Setup and create an easy scenario with nothing but MeatSims. Save the scenario, then access the Load Settings screen -- but don't load anything. Now use the second controller to select a challenge you would like to beat. Press Start until it says "ready and waiting."
Finally, use the first controller to load your scenario. You will now be able to play the challenge with the easy settings of your custom scenario. This trick will work with all challenges, but you have to change the combat setting depending on the type of challenge (eg: Hold the Briefcase or King of the Hill). You can use this little trick to completely customize the challenges, including the time limit.

The following trick isn't for the game, but rather for Nintendo's "secret" promotional website. To break into the Carrington Institute website, use the following user name and password:
Username: solaris
Password: pal32ver21z
Enter these at the 'agents only' section of the Carrington Institute's site and you'll be granted access to a new area complete with information on "CI Scientists Missing", DataDyne files recovered, biological sampling system and intelligence reports.
In the multiplayer level Warehouse, go to the large main room with all the walkways and go into the one with the hole near weapon spot 5. Look above you and without falling in the hole, take out the FarSight XR20 and you'll see a vent with a question mark on it. A cheesy easter egg for Nintendo, but don't forget this was 1998.
