Except jjkill cannot be used.

jjpageclaim

I've used it. It kills you.

Left, Left, Right, Right, Up, Down, Up, Down, A, B, Select, Start.

Or...

L1, R1, Circle, Square, Triangle, then hold down left on the right anolog, down on the right anolog, and reset the system (Hold L1, L2, R1, R2, Select and Start)

jjdance - Message appears: "Ye puts thine point on ye floor and just grooves it."

jjyourheadasplode - Character's head asplodes. (yes, i know, it's really explodes, i'm not that dumb)

jjfan big fan blows your rabbit away
jjlistserver finds all jj2listservers on the internet
jjwoot WOOT!
jjscarymode puts pictures of michael jackson in the level.

jjwhatever - Exit's game without further questions.

Left Right Up Down A + Start.

jjifyouwilltypethislongcheatnothingwillhappen (nothing happens)

jjgivemethatiwant (gives you anything you want, but if it cost 1$ or less)

jjcrash (crashes your system, works under Windows 9x/ME/2000/NT/XP and Linux)

jjallammo
jjpowerup
jjcarrot

jjmegasux - Everything turns to 1bit.

i like that one alot MSB3000 :)

jjpeep- Turns the game into 0 player mode. Can you handle it?

jjbloodandgore More blood and gore in the game, like head shots, blood, losing arms and legs etc.
jjbushandgore Haha, Bush and Gore.....

iknowkungfu - :D

jjDerby :)

Well, I might as well join in.

jjmoo - Turns Jazz into a Cow
jjfish - Turns Jazz into a fish and raises the water level
jjjumpoffacliffanddie - Kills Jazz, except with a really cool death sequence
jjcheat - Instantly crashes the game with error message "OMGHAX!"
jjnumberjj2 - Plays a random quote from #jj2 on irc.quakenet.org
jjwallclimb - Allows you to wallclimb by yourself.
jjapan - Changes the language to Japanese.
jjwheeesplat - Same as jjjumpoffacliffanddie.

That's it, I'm all out of ideas here.

jjteleport - Teleports Jazz to a random open spot in the map.
jjmech - Jazz can use a mech! ;)
jjmoustache - Jazz gets an moustache, type cheat more times for different moustaches.
jjremote - remote detonator for TNT.

This is actually a great idea. Imagine Lori with a moustache ;P Is it just me, or you took it from Lego: Star Wars?

However, there are some more logical ideas:
jjfur # # # # - Changes your fur color.
jjspeed - Makes you run even faster.
jjammo - Unlimited ammo.
jjconsole - Opens the console.

jjsu # - disables chats from a certain client

Derby: Acronym clearance.

Would that be width or height?

1D as in 3D, I think.

jjtinytiny - Jazz gets really small.

Depth!

jjdemo - stops or starts recording a demo movie
jjrec - stops or starts recording sound from the game

It's just you, I don't have Lego Star Wars. (It was rated better than the real Star Wars game by a dutch gaming magazine!)

jjbot - A second rabbit as your co-player controlled by the pc.

jjtrip - puts you into an endless dizzy mode from that catarpillar with the waterpipe!

JJplaylikebobbyakadizzy

For what it's worth, the same cheating system has not yet been used in more than one engine. Seeing as this topic is about a JJ3, there is no reason codes would begin with JJ.

.. JJthereisnospoon.

anyone? Hehe.

If you are talking about the game cliffy talked about then....

jjclassic-all the enemies and jazz are turned to the classic ver.
jjbigh-Big heads on everybody.
jjgibs-BLOOD EVERYWHERE!
jjfat-Useless cheat...makes jazz very fat and slow...good point is you can jump on enemies head. It is less usefull if you could roll around.
jjsonic-this won't be in it but...you play as sonic with no gun. you just are ten times faster.
jjtaunt-you taunt your enemies thats it.
jjbeard-Gives jazz...a beard.
jjcarrot-get a carrot
jjgod-duh.
jjk-die jazz
jjspaz-play as spaz!
jjlori-play as lori!
jjearl-play as ms. earlong.
jjpie-changes all the weapons to be food related. like flame thrower=whip cream shooter.

Most of those cheats sound pretty cool! Too bad they're not included in the game....

Anyways:
jjmindcontrol - Jazz can mindcontrol an enemy and use that one to attack.
jjshroud - The whole map is covered with black shroud that can be revealed be walking into it.
jjchuckfix - Allows chuck to shoot.
jjshell - turtle shell drop right in front of your nose.

icamefromjaleco - does the same as "arjan" in JJ1

jjgiant and jjtiny would definitely work

How about
jjfood (changes every monster in the level to food)
jjreverseg (reverses gravity yes that would suck with one-ways)

followthegreenrabbit - wireframe mode
mypcsucks - turns off textures
0wn4ge - game becomes 2x faster

*cough* overrated *cough*
JJplaylikemessiah

We don't really have anything else to base the cheats on.. *shrugs*
I don't remember the cheating system in JJ1 anymore, either.
