FREEZING
Unfortunately, this is not cool, but we feel it should be addressed somewhere on the site. Many players have experienced trouble with their copies of Metroid Prime freezing up on them either while Samus is on an elevator or moving into a new area. Contrary to popular belief, this is not due to scratched disks, dirty Gamecube drive lenses, blocked vents/overheating, or a bad batch of games. It is a bug in the programming.
While you are playing, take note of what your Gamecube is doing -- Metroid Prime is programmed to load new areas constantly as you move throughout the game ( notice there are no "Now Loading, Please Wait"-type screens in the game). Sometimes, the player may attempt to move forward faster than the game can load information for the next area, and the game will freeze. If the game freezes on an elevator, it´s pretty much unavoidable. However, the game also often freezes in long tunnels. Most of the long, S-shaped tunnels in the game are actually loading areas. The reason they are curved and often contain enemies to fight is to slow the player down and to give the game time to load the upcoming area. In fact, you can intentionally crash the game by rushing through some of these tunnels and trying to reach the next area before it loads.
The best way to prevent freezing is to listen to your Gamecube as it reads data. If you´re approaching a door or passage and you hear your GC´s drive working like crazy, let it finish before moving on. ( Notice that oftentimes you may shoot a door, but it won´t open for a few seconds while the area loads.) By doing so, you should avoid any crashes or freeze-ups. So be careful, don´t rush, and save often! ( It´s quite possible that this is the reason why Metroid Prime´s endings are not based on speed!)
