Chameleon Twist is a short game starring four alleged-chameleons that followed a White Rabbit to a strange world. Then they just start beating up everything in sight...

Unused Shoe Monster

This odd shoe monster has a full set of animations for each angle, like the rest of the enemies in the game.

Looks like this guy got the "boot"!

Uncompiled Source Code

At 0xF4B6C in the US ROM, the following code fragment for the credits can be seen. Note that this uses EUC-JP encoding.

Regional Differences

Apparently, Japan kept all the good stuff for themselves. The international releases seem positively unfinished in comparison!

General Differences

  • In the international release, the Sunsoft logo appears before the Japan System Supply Logo. It's absent in the Japanese release.
  • Battle Mode cannot be entered with one player in the international release. In Japan, however, one player can enter to play against CPU players.
  • Throughout the levels, powerups are placed in areas where they may be useful. In the international release, these powerups are only present in Battle Mode. The powerups are:
    • A black, pentagonal shape that causes the chameleons' heads to grow, enlarging the enemies they spit out as ammo.
    • A red ball surrounded by three triangular shapes. This makes the chameleons shrink down. This is mainly used to get into small spaces.
    • A stopwatch, similar to the one the White Rabbit uses. This freezes all enemies in the room for a small amount of time. This powerup is nowhere in the international release.
  • The White Rabbit greets the player before meeting every boss and gives them small hints on how to defeat them. This was brought back in Chameleon Twist 2.
  • There are now 6 Carrots to collect. These will allow the chameleons into mini-games and secret areas. This feature was also brought back for the sequel.
  • The boss of Bomb Land drops bombs much faster.

Memory Pack Warning

In the non-Japanese versions, if you start the game with the Memory Pack inserted, you'll receive a warning message. This message does not appear in the Japanese version.

Level Layout

Some levels have had drastic modifications to their layout.

Ant Land

In the fourth room you can go into, there is a ring of crowns surrounding a single orange Heart in the international release. This was replaced with an area full of rising platforms, wooden poles, and marching Ants in the Japanese release.

International Japan
It seems so simple... This seems... less simple.

In the large room filled with worms, the international release got... a large room filled with worms. Meanwhile, Japan got two, seesaw-like platforms and two crowns. It also has a slightly different floor texture. The worms' mud mounds that signal where they will pop up were also removed in Japan.

International Japan
If they were any bigger, this would be Tremors: The Game! I'm safe here...

The Fight against the Ant Queen now features a health display. Also, the Japanese release moved the ceiling higher up, for whatever reason.

International Japan
Baby got thorax! Chameleontwist-bosshealthbar.png

Desert Castle

The first spike platforms the player encounters are made up of two straight platforms in the international release. Japan made a decidedly less straight path for their spikes.

International Japan
At least the spikes are polite enough to to skewer my tongue! Chameleontwist-desertspikesJAP.png

Like the Ant Land boss, the Desert Castle boss has also been given a health display.

Kids Land

In the fourth room, there are but three platforms and a crown in the international release. In Japan, there is a swarm of ice cream sandwiches, a glass box with a crown in it, and five platforms. After all of the ice cream sandwiches are destroyed, a shrinking powerup appears on the fifth platform. The player can now go into the box to get the crown. If the player is still in the box when the powerup wears off, the box shatters.

International Japan

The fifth room has also been modified: In the international release, there is a large stack of crackers leading up to a tall wall with a wafer creature waiting to be hit. In Japan, the wall has been made much shorter, and the crackers have been replaced with a pit. In the third room with wafer monsters, the exact same modifications have been made.

International Japan
Is anybody else feeling hungry? ...Because I've suddenly got a craving for chocolate and wafer bars...
This is bowling. There are rules.

The most significant difference, however, is the addition of a bowling minigame. In the area with three platforms encircling a wooden pole, the White Rabbit is standing by a door. If you have a certain number of crowns, he will let you pass through to play the game. This area is like bowling game in Chameleon Twist 2, but you can't position the ball, making it significantly harder. If you get enough points, a crown will appear in the room. The pins will also take on the appearance of the player's chameleon, just as it does in Chameleon Twist 2.

Ghost Castle

The entrance to the Pool mini-game has been moved. In the international release, it was set right near the level's entrance. In Japan, it was set in one of the early rooms, with the Rabbit standing right outside.

International Japan
Oh man, I only have 49! Wait, what's that over there...? I don't suppose that's the fire escape?

....? (Boss Rush Stage)

Six segments now?! I'm screwed...

In the international release, there is no difference between the bosses' fights in their stages and in this stage. However, Japan made the Boss Rush battles much more challenging than in their stages. All of the bosses have been made faster, stronger, and mind-bendingly hard to beat.

White and Black

White? Really? That's the name you're going with?

After beating the game once, a white chameleon is unlocked. This chameleon is aptly named White. White has no abilities or quirks that set him apart from the other chameleons. He's just... white.

"Okay, this black one here? His name is black... What do mean it's uncreative?!"
White vs. Black - So what else is new?

There is also a black chameleon to unlock. This chameleon is named, of course, Black. Unlocking him is not as easily done as White. In Bomb Land, there is a barred doorway, guarded by the White Rabbit. To get past the bars, the player must collect all six carrots from the game. Through the door is a small arena, with Black standing in the middle. The player must defeat Black to get a crown. After his defeat, he is unlocked for Battle Mode, but not Story Mode. Black cannot be unlocked as playable for Story Mode, perhaps to keep from having Black face off against himself, though he can easily be hacked into Story Mode.


In the Japanese version, when the last boss dies the player's chameleon escapes through a narrow hallway before showing the credits. In the international version, the screen fades out to the credits directly.

Perfect Code

To do:
Find out what this code does.
The perfect code?! Wow! ...So what does it do?

After beating the game once, a new challenge appears: After starting a new game, a star is put in the corner of the screen. If the player gets hurt even once during the course of the entire game, the star goes away. However, if the player is not hurt once throughout the entire game, the game will show a special code, called "Perfect Code", after the credits roll. After this happens, the Code will be displayed on the title screen for all to see. At this time, it is unknown what the code does, if anything.
