SM64 N64 Behaviour Change Codes
(JS) Codes by me.
Codes that change the way objects behave including spawning different items to normal.
Please use the links on the right for the various codes.
Note: please use the appropriate PAL (Europe) /NTSC (US) code for your N64 or emulator ROM.
You can email me at james.boshikoopa@gmail.com
For more codes please go to the main SM64 Codes page.
Koopa the Quick moves much faster (JS)
Activate this code before the title screen appears.
NTSC
812FD21A 4220
In Bob-omb Battlefield Koopa the Quick will run really fast.
Note: Koopa may get stuck especially if you interact with him while he's running. Also, you may find him before the top of the mountain claiming he's won even though the timer is still running.
Gates in Bob-omb Battlefield replaced with Chain-chomps (JS)
Activate this code before the title screen appears. In Bob-omb Battlefield (any star) you will find that instead of the 2 gates that are opened by the switch there are 2 Chain-chomps guarding the switch! Your mission is to press the switch to release the red coin star but the switch will only work if you are standing on it while holding something. Can you do it with a Bob-omb or perhaps the small box you can pick up?

Heart follows Mario (JS)
Turn this code on before the title screen appears. Go to a course with a spinning heart (e.g., Bob-omb battlefield) and when you get near it, it will home in on Mario and recover his health.

Note that when you enter Bob-omb Battlefield the '1-up appears' sound is played; this is the same for any other levels that have the spinning heart. Also, the 1-up sound will continually play whenever the heart is near Mario. If you use a warp the heart will be gone. Because this code modifies the homing-in 1-up mushroom it will recover health instead of giving a life.
Red and blue flames kill Mario instantly (JS)
Turn this code on before the title screen appears. Mario will be killed by any type of red or blue flame.

Monty Moles throw Fly Guys! (JS)
Turn this code on before the title screen appears. Then go to either Hazy Maze Cave or Tall, Tall Mountain where you will find that instead of the dirt that the Monty Moles normally throw they will instead 'throw' Fly guys!

Swap certain basic object behaviours around (JS)
Approaching a tree causes Mario to spin around. If touch an Amp, Mario will be thrown far back and his cap will fall off. If Mario tries to ride a Koopa shell, he will keep getting set on fire! If you try to pick up a box you will get pushed away, but you can bounce on its top. When using certain types of warps, such as in the flowerbeds, Mario will act as if walking through a door before warping. As for Goombas, if you get close enough to them, Mario will just walk through as if the Goomba were a door. Lastly, if you try to talk to someone or read a sign then you'll get quite a shock!
For some extra fun when using this code: talk to a Toad; jump onto a Bob-omb (see how many times you can keep jumping!). Inside the castle on the first floor, touch the wall near the door that leads to the Bob-omb Battlefield painting room (then look on the other side to see why it shocks you).

All Visible Objects Home in on Mario! (JS)
Turn this code on before the title screen appears. Press D-pad up to make all visible objects (that are near enough) home in on Mario and press D-pad down to stop them homing in. Because there can be so many objects at once, however, the game may crash and with some levels the game may crash as soon as you enter the level, including outside the castle; the code works best in Bob-omb Battlefield. Also, if you go near where there is a homing in 1-up the game will crash.

Note that because this code makes use of the homing in 1-up behaviour by modifying it, the homing in 1-up mushrooms will no longer work how they should (they will chase Mario and circle round him until they fade).

Get Piranha plant from Goombas (JS)
Turn on this code before the title screen and then make your way to a level such as Bob-omb Battlefield or Tiny-huge island (works also for big Goombas if you stomp them). Now a Piranha plant will pop out of a goomba instead of a yellow coin. Also, this code works for other objects that you would usually get yellow coins from including the wooden posts that you run around, but only one Piranha plant will appear.
It's possible that the piranha plant from the Goomba will appear in the air and stay there as it's not affected by gravity.
