Ending bonuses:
Successfully complete the game as Jill or Chris and save the game. A new background will appear on the main menu. Select the "Once Again" option when playing your completed saved game. You may now choose new difficulty settings for the replay. You will also get a key that will allow the character that completed the game to have a new costume. Enter the room with the large mirror on the second floor of the mansion. Unlock the door in the back. Enter the closet and move all the way to the end of the rack of clothes. A message asking "There is an outfit that fits you perfectly, do you want to put it on?" will appear. Select "Yes" to change your character's clothes. Complete the game again under a different difficulty setting to unlock a second costume. Jill's bonus costumes are a commando uniform and her costume from Resident Evil 3. Chris' bonus costumes are casual clothes and his costume from Resident Evil: Code Veronica.

Successfully complete the game as Jill or Chris with a time less than five hours. Save the game at the end, then start a new game to begin with the Samurai Edge gun.

Successfully complete the game as Jill or Chris with a time less than three hours. Save the game at the end, then start a new game to begin with the Rocket Launcher with unlimited ammunition.

Successfully complete the game in once again mode under the normal difficulty setting with a time less than five hours. This unlocks the "Real Survivor" option (item boxes do not transfer items to each other), the .40 Smith And Wesson gun with unlimited ammunition (replaces the combat knife in a new game), and bonus costumes. Additionally, the aiming system will be manual.

Successfully complete the game two times as Jill or Chris to unlock the "Invisible Enemy" option. All enemies will be transparent in this mode.

Successfully complete the game as both Jill and Chris one time to unlock the "One Dangerous Zombie" option. When this option is enabled, a special zombie will keep following you around during the first part of the game. Shooting this zombie will end the game, so you must avoid it during game play.

Successfully complete the game in invisible enemy mode with a time less than five hours to unlock a "Special Features" option that displays a message from the game developers and a gallery of pre-production costumes.

Hint: Alternate Jill scenes:
When the game puts you and Barry in the dining room, wait until Barry sees the blood, then run back to the hall where Wesker is located. Wesker will tell you to " Investigate shots if heard". You will then be put back in the dining room. Try to go back in the hall and Barry will say "Cold feet already Jill? That's not like you.". When you try to walk to Barry, a alternate beginning sequence will appear.

There is a different arrangement of scenes that happens from the usual when you start a new game as Jill. After the "Cold feet" comment as described above, you will resume control of Jill. Go up to the fireplace where Barry is located. The game go through as normal saying, "'It's blood, let's hope it's not Chris'. Investigate the room for clues while I look at this." Have Jill go by the left side of the dining table (towards the clock) and a new intermission sequence will start.

Perspective, from side door
(Door knob turns)
Jill - "Who's there?"
(Door slams open and a zombie comes through and sees Jill.)
(Jill backs away as the zombie follows her,)
Barry - "Hey you! Get away from Jill!" "This guy is crazy!"
(Barry takes two shots and kills the zombie.)
Barry - "What the hell is this thing?" (This is Jill's line when it is done the normal way)

In the original PlayStation version of the game, this trick would make you able to take down zombies in three gunshots, but apparently it will not in the Gamecube version.

Glitch: Unlimited grenade ammunition (Japanese version):
Equip the Grenade Launcher with any type of ammunition, then take Flame Rounds from an Item Box. Open the Item Box again and put the Flame Rounds back into it. On the Item Box Inventory screen, highlight the slot with the Flame Rounds and press A. The pointer will jump to the Grenade Launcher slot. Press A to get 456 Flame Rounds. Note: This can also be done with other types of grenade ammunition.

 

 

I think this works on the us version to.
