Are you a bad enough dude to rescue this article?

Rhythm Tengoku is what happens when popular Japanese music producer/singer Tsunku♂ partners up with the team behind WarioWare - a weird but awesome rhythm game filled with all sorts of wacky characters (and lots of monkeys), which further resulted in the Rhythm Heaven series.

While exclusive to Japan, it actually requires little to no knowledge of Japanese to pick up and play, making it a good (and popular) import title, though a fan translation is available. It's also the last first-party GBA game, coming two years after the Nintendo DS' launch.

Unused Rhythm Games

Tanooki & Monkey

Please elaborate.
Having more detail is always a good thing.
Specifically: Explain what needs to be done to access this.
A screenshot from the Rhythm Game. Tanooki and Monkey are on the left, the monkey-like drummer is on the right.

An unused Rhythm Game where you control a monkey-like drummer, who's tasked to copy the patterns that are played by Monkey and Tanooki. The game controls the same as the Drum Lessons from the final game, but only A, Right, and Down are used on the patterns. The player is given three attempts at completion for each pattern. Upon completing the game, the player is taken to the Rhythm Test result screen. Upon losing the game, however, the player is taken to the Ratings Screen. It doesn't go much farther than that, though, as the game crashes shortly after.

Tanooki & Monkey also has text to go along with it!

To do:
Add the rest of the Japanese text.
Cacti may speak Japanese, but do they speak it well?
...But does it make sense?
The translations on this page need to be proofread. If you are fluent enough in this language, please make any corrections necessary!
Japanese Translation
こんにちわ! Hello!
We're Saru and Ponta.
We've come here to play on the Drum Samurai's introduction.
今回は ボクたちが
This time, we're giving the lessons!
Now, without further ado, let's practice hitting that A button.
よく きいて
Listen well and repeat!
Ponta will join in too.
Ponta's sound is playing by pressing "down" on the D-pad.
Next is a fast part.
It's easier if you alternate pressing "A" and "right" on the D-pad.
練習は 次で最後です。 This is the last stage of practice.
Seem tough?
Good luck!
All right, come on, let's have a rhythm battle!
3回 チャンスが
You get 3 chances for each pattern.
I wonder how far you can go?
Okay, let's start out simple for now.
つぎ いってみよう!
Okay! On to the next one!
Think you can handle it?
Good work.
For the next pattern, Ponta will play too!
つぎのは ちょっと
Wow, great!
The next one's a little more technical!
Heh, you're pretty good!
Looks like it's time for our trump card!

If the player wins:

Japanese Translation
We lose! You win!
また、あそんでネ! Come play with us again sometime!

If the player fails a pattern:

Attempts Left Japanese Translation
2 やりなおし!
One more time!
You get two more tries.
Good luck!
1 やりなおし!
Try again!
This is your last chance!

If the player loses:

Japanese Translation
Game over!
Looks like we win!
また挑戦してネ! Take us on again sometime!

Rhythm Games

Rhythm Tengoku KarateMan Icon.png Karate Man

Unused Background

These are background graphics that go unused in the first Karate Man rhythm game. They can be activated if 0x089CFF05 is changed to 0x01 in a memory viewer.

Rhythm Tengoku Spaceball Icon.png Spaceball

Unused Sprites


A flowerpot with a face, an apple, and a star all go unused. The apple was most likely replaced with the rice ball, and the star is a graphical replacement for the baseball since it can be activated by changing the baseball GFX.

Unused Variants

Please elaborate.
Having more detail is always a good thing.
Specifically: How does one go about accessing this? Is this a test or what?

There are two unused variants of Spaceball present in the game's file. Both variants use the second minigame selection track.

Rhythm Tengoku Remix1 Icon.png Remix 1

Please elaborate.
Having more detail is always a good thing.
Specifically: Add the videos of the dance classes to the prerelease page, they feature a variant of the song from this Remix.

Located on page 8 of the Debug Menu, labeled as ダンスレッスン1 (Dance Lesson 1), is an early version of Remix 1! This version of Remix 1 is a minute longer than the final, using unused portions of Remix 1's music (with a few parts of it being reused in Remix 7). The most interesting thing to note is that Rhythm Tweezers is absent in this version and has been replaced by Tap Trial! This implies that it was either originally in Stage 1 but was then moved to Stage 5 later in development.

It's named "Dance Lesson 1" after the dance classes the development team had to take during the game's development, as recommended by Tsunku♂.

Rhythm Tengoku BunnyHop Icon.png Bunny Hop

There are two unused sprites for the A button and D-Pad within the Bunny Hop sprite sheets. The game might have been planned to have the A button and D-Pad interchangeably, similar to Rhythm Tweezers.

RhythmTengoku-Bunny Hop unused A+.png

Rhythm Tengoku SpaceDance Icon.png Space Dance

To do:
Re-rip these graphics with a transparent background. We also don't need that second image, and can just use text to explain it.

Rhythm Tengoku NightWalk Icon.png Night Walk

To do:
As seen in the arcade port page, there are also some unused sprites of Play-Yan, including one where he crouches, like in the Play-Yan minigame JUMP. Rip those sprites.

Nightwalk crab.png Nightwalk duck.png

A crab and a duck, which both go unused. These might have been a reference to the Play-Yan for the Game Boy Micro.

An unused sound for Play-Yan screaming. This could have been used when Play-Yan fell off of the stairs after the steps disappeared. It doesn't appear in its sequel either, suggesting it was cut before either one was finished.

Rhythm Tengoku TossBoys Icon.png Toss Boys

To do:
Rip the sound effects instead of having two separate YouTube videos.

Located within Toss Boy's soundbank are some unused SFX. With new SFX, comes new combos. These include:

  • Aka-Chan saying "Ao-Kun" in a louder, longer fashion;
  • Aka-Chan saying "Kii-Yan" in a faster manner;
  • Aka-Chan saying "Kii-Yan" in a louder, longer fashion;
  • Aka-Chan's 3 Grunts (Hoomph);
  • Kii-Yan saying "Aka-Chan" in a louder, longer fashion;
  • Kii-Yan saying "Ao-Kun" in a louder, longer fashion;
  • Aka-Chan saying "Hey!";
  • Ao-Kun saying "Pachi!," a Japanese onomatopoeia for a clap

Rhythm Tengoku TapTrial Icon.png Tap Trial

To do:
Rip and add the unused Pig sprites along with the unused sprites for the Remix 5 and Remix 7 variations of Tap Trial.

There are a few unused sprites meant to replace the giraffe for the different versions of Tap Trial, but only the original giraffe ever appears in the final game. Remix 7 would've utilized the dragon, and Tap Trial 2 might have, at one point, used the camel.

Rhythm Tengoku-unused-dragon.png Rhythm Tengoku-unused-camel.png

The Pigs from Remix 7 also have finished sprites for jump taps and triple taps, which are not used in the final game. The girl that is used in this version winks if you do a jump tap correctly. These sprites can be seen by editing the memory values at memory address 0x089D1CA1 to 0x02.

Rhythm Tengoku RapWomen Icon.png Rap Women

This unused variant of Rap Women can be found on Page 6 of the Debug Menu, labeled as ラップウイメン(by KAZU), with the other option, labelled as "by YONE", being the version used in-game. This version is likely named after Kazuyoshi Osawa, the Chief Director of Rhythm Tengoku; similarly to how the used "YONE" version is named after Masami Yone, who was the game's Sound Director.

The audio cues in this version are placed differently than that of the used version, most of which being on offbeats. It was likely changed to make the song flow better with the lines from the characters, however this has yet to be proven true.

Ratings Screen

Unused Graphics

RtUnusedOK.png RtUnusedTryAgain.png

Early versions of the OK and Try Again graphics.

Rhythm Tengoku Unused Judgement Screen.png

This directly translates to "Norikan Check", with "Norikan" being the Japanese term for "Flow". This appears over the white oval with text that serves as the caption on the rating screen after completing certain unused games in the debug menu.

Rhythm Test

Unused Graphics

To do:
There are unused, earlier versions of the Rhythm Test present that are still accessible via the Debug Menu, document them.

Fever, prescription, etc.

Sprites of a cowbell are present within the Rhythm Test's graphics, it might have once been intended to be used for a timer's ending tone.

Game Select

RhythmTengoku Medal.png Rhythm Tengoku Unused oval.png RtSquares.png RhythmTengoku R-IQ.png RhythmTengoku R-games.png

Graphics from an earlier version of the Game Select screen. "Rhythm IQ" was a working title for this game.

Rhythm Toys

Meow Mixer

To do:
Technical stuff.
Rhythm Tengoku Meow Mixer Unknown.png

These graphics go unused in Meow Mixer normally, they show different Japanese characters.

Japanese Translation
Ears are speakers

To do

Rap Machine


Hidden in the background layer for this game is an early version of the "controller".

Unused Text

Japanese Translation
なっとくの せいかくさ
Natoku no Seikakusa
Lesson (Experiment 8)
リズムお習字 2
Power Calligraphy 2

Some unused text that isn't used in-game. There would have been an eighth Drum Lesson experiment, and Power Calligraphy doesn't have a sequel version in the final game, so these are unused. The second text string can be seen in the Debug Menu, and the third text string can be seen in the unused Gameplay History, also featured in the Debug Menu.
