Alternately, find an item box and dump your entire inventory into it. Next, place the Grenade Launcher in the upper-left item slot and your Incendiary Rounds in the upper-right item slot. Then, equip the Grenade Launcher. Go back to the item box, highlight the Incendiary Rounds in your inventory, and press A(2). Then, go over to the Incendiary Rounds (which should be in the item box) and press A(2). If done correctly, you should have 240 Incendiary Rounds.

In the Japanese version of the game, 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.

After you have completed the Rocket Launcher glitch to get more grenades, continue press A, alternating Grenade Ammo. Switch out and it will fill the rest of your inventory with about 200 rounds for each unused space.

Note: Use the following trick to clone grenade rounds and get unlimited ammunition. Have a full inventory the first time Barry is supposed to give you the Acid Grenade Rounds, so you cannot get them. Continue the game and you can get a set of six Acid Rounds in the garden shed (just before the Hunter enters the mansion). Go to the kerosene save room at the bottom of the stairs (by the broken door). Use the "Unlimited grenade rounds" glitch to increase your Acid Rounds inventory. If done correctly, your number will not increase, but % and a random number will appear. Leave the item box and put the Acid Rounds into the Grenade Launcher. The acid rounds will load, and a new set of acid rounds will remain with a large number displayed beneath it. Combine the Explosive Rounds and the same thing should happen, allowing your to clone and mass produce grenade rounds. In order to clone the flame rounds, you must continue cloning and cycle through all of the grenade types. Eventually, if you are lucky, your flame rounds will also begin to clone.

This is a step by step guide to getting this glitch to work. Follow these instructions or it will fail.
Requirements: You must have the grenade launcher and two types of ammo (e.g., Grenade Rounds, Incendiary Rounds)
1) Put all items in item box
2) Put Grenade Launcher in upper-left item slot
3) Put Incendiary Rounds in upper-right item slot
4) Close box
5) Open inventory
6) Equip Grenade Launcher
7) Open box
8) Select Incendiary Rounds from inventory
9) Press ''A'' twice
10) Move cursor to Incendiary Rounds inside box
11) Press ''A'' twice
The amount of Incendiary Rounds in the Grenade Launcher will now increase. The number value will be graphically glitched. Close the box and open inventory to fix that. I assume the value exceeds the possible amount, so the game automatically reduces the rounds to 240 to prevent data corruption. Enjoy.
This also works for other types of grenade ammo... But why you'd want anything other than Incendiary Rounds is beyond me.
NOTE: This code does not work in the PAL version of the game.
Near the end of the game in the Laboratory, you will reach a computer that you have to enter passwords into in order to progress through the game. If you enter the password "MOLE" from the original game, you will actually hear Tofu from Resident Evil 2 on the computer screen. Strangely, this only works on Easy Mode for some reason.
If you unlocked the new costumes for Chris, change his outfit. If you run into Rebecca with a new costume, she will be wearing her western outfit. Every time you switch a costume (new ones to old one), she will switch hers as well.

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.

One way to see if a zombie is dead is to face away from it and press R. You should automatically turn around to face the Zombie if it is still alive.
To make sure that a Zombie has died when it falls down after shooting it, look down. If you see a pool of blood flowing, it is dead. If there is no pool of blood, the Zombie is still alive.

If the zombie is on the floor and is still alive, its head will keep turning side to side.

If you are not sure if a zombie is dead, back up away slightly so that you can see the body. If there is a blood pool around it, it is dead.

In the area surrounding Lisa's cabin in the courtyard, there is a side path that loops around the cabin and ends up back at the main trail. There is a particular viewpoint in the area where a tree takes up the left side of the screen. If you wait long enough, a rhinoceros beetle will clamber up the tree. This resets every time you change angles and return.
