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 later a 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.

Note: all offsets listed here are pertinent to the revision 0 (Rev. 0) ROM unless specified otherwise. If you are playing a revision 1 (Rev. 1) copy, offsets mentioned may not be accurate.

To do: Ongoing decomp could help provide insight. More stuff from this game might've been posted on the Rhythm Heaven Modding Discord.

Debug Menu

A screenshot of the Debug Menu. The top-left text translates to "Sequence Test".

In February 2017, a fully intact debug menu was found within Rhythm Tengoku. Most facets of the game are present and accessible, organized into 14 pages (1-E), each containing a maximum of 8 entries.

To access the debug menu, make the following changes to the corresponding ROM in a hex editor:

Rev. 0			Rev. 1
Offset	Original	Edited	Offset	Original	Edited
9DD478	60 D2	24 DB	9DD448	30 D2	F4 DA
9DD480	58 D4	A8 DB	9DD450	28 D4	78 DB

Once finished, the menu should load in place of the title screen.

Unused Gameplay History Menu

...But what does it mean? This game has text or audio that needs to be translated. If you are fluent with this language, please read our translation guidelines and then submit a translation!

A screenshot of the menu. The top-left text translates to "Gameplay Logs".

Accessible via the aforementioned Debug Menu is an unused menu that shows the play history for each available item in the Game Select menu. With it, the player can view:

• The average amount of points scored across all plays (out of 1000).
• The total amount of times the game was played.
• The numbered playthrough they achieved their first OK on.
• The numbered playthrough they achieved their first Superb on.

The games in this menu, for the most part, are listed in the internal order stored in ROM, rather than in unlock order, similar to how they are listed in the Debug Menu. Notably, the menu implies the existence of Power Calligraphy 2, as an entry for it can be found after Power Calligraphy. A gameplay history menu would later be incorporated into Rhythm Heaven Megamix.

Text used in the menu:

Japanese	Translation
平均点 X (1000点満点)	N/A
遊んだ回数 X回	N/A
初合格: X回目	N/A
初大合格: X回目	N/A

If a game has been played, but an OK or Superb isn't yet achieved:

Rhythm Shiryo Shitsu Notification

A screenshot of the notification.

Listed as Ｒ−ＩＱ　（にゅうか） in the Debug Menu is an unused notification screen for Rhythm Shiryo Shitsu. The player is told that they've received a new letter, and can choose to either read it now, or return to the previous menu. Which letter in particular the player receives is randomized each time the screen is accessed.

Unused Code/Parameters

Karate Man

Unused Version Setting

Loading the engine for Karate Man with a version setting of 0x01 introduces unique properties to the game that aren't used elsewhere. One such property is that, each time an item is hit, one of two unused backgrounds depicting different characters making a facial expression is overlaid over Karate Man's regular background, depending on how well the input was timed.

• 

  Appears if your timing was just right.

• 

  Appears if you were early/late, or if you hit a rock/bomb with low flow.

Aside from that, this setting also alters the sound effects for hitting an item, defaulting to the high-flow variants regardless of actual flow level.

BG Face Reset

Related to the unused version setting is an unused function that resets BG Layer 0 (the layer the unused backgrounds are written to) to a third unused background that's initially loaded with the engine, though never displayed and eventually overwritten with one of the aforementioned backgrounds.

Spaceball

Unused Cue Settings

There are two unused settings for the cue command that spawn balls with different input timings. 0x00 spawns a ball that’s hit in 0.5 beats, and 0x03 spawns a high ball that’s hit in 1.5 beats. While 0x00 appears to play no sound effects when the ball is pitched or hit, the code internally defines a dummy sound, s_f_dummy_vol0, as the sound to play for those actions, suggesting that the cue was to get its own sound effects.

Unused Ball Type

The command that changes the sprite used for the ball has an unused setting (being 0x02) that swaps it for the unused star graphic. This can be seen in the unused Spaceball sequences.

The Clappy Trio

Unused Version Setting

Loading the engine for The Clappy Trio with a version setting of 0x05 will load its sequel variant with four lions instead of three. The quartet is only ever seen with the graphics from its base variant, leaving this version unused.

Sneaky Spirits

Located at 0x00A7A20C is an unused subroutine that simply rests for 8 beats.

Iai Giri

Like Sneaky Spirits, there's an unused subroutine that does nothing for 8 beats, located at 0x00A053F0.

Sick Beats

To do: Are these really worth documenting here? It seems like both of these observations are the consequences of a function accepting an arbitrary value as an input, rather than something that was explicitly planned to be used.

The graphics function that controls the virus palettes has some unused values that change the viruses into other visible palettes.

There also exists unused hit counters, most of which turn the viruses invincible, but one makes the virus require 4 hits to be cleared.

Showtime

Unused Cue Settings

The cue command for this game has two unused settings that spawn a version of the white penguin requiring an input to be made in 1 beat, as opposed to the standard 2. Of these settings, 0x02 curiously spawns a non-swing variant, unfitting with the song used in-game. 0x03 meanwhile spawns what you’d expect.

Power Calligraphy

To do: Unused cue settings for the third stroke in 力 and fourth stroke in 心.

Ink Particle Effect

A function for this game exists that, when re-added, causes particles of ink to expand from and quickly contract into the brush. The function has a single parameter which controls how long the effect lasts, and likely would've coincided with the charge-up before a cue.

Energy Dissipate Effect

Code exists for clamping an animation of energy dissipating to the coordinates of the hand and playing it when the hand finishes charging. It goes unused due to the animation not being made visible when it actually happens.

(Source: GENERIC)

Swing Subroutines

Subroutines for preparing the pages and drawing the 寸 symbol, 、symbol, and the face that appears at the end of the game have variants in swing rhythm made for Remix 4 that ultimately go unused. Their locations are as follows: 0x00A81478 (Prep 寸), 0x00A814FC (寸), 0x00A823B4 (Prep 、), 0x00A82414 (、), 0x00A82690 (Prep face), and 0x00A82714 (face).

Toss Boys

To do: Each one of them can do each-others moves.

Unused Cue Settings

There exists unused cue settings for the trio (0x04 for Aka-chan, 0x05 for Ao-kun, and 0x06 for Kii-yan) that causes them to catch the ball, utilizing animations that otherwise go unused. After the ball is caught, inputs for whoever caught the ball no longer affect that character.

Tap Trial

Unused Version Setting

Loading the engine for Tap Trial with a version setting of 0x06 causes the game to randomize its appearance on both inital load and each subsequent engine call, meaning that it may appear as Tap Trial 2 initially, and then appear as the Remix 5 variant when the game gets loaded again. An unused sequence for Tap Trial is the only game that uses this feature.

Unused Audio

As audio heavy as Rhythm Tengoku is, it's no surprise that some sounds would find their way here. The filenames for these entries originate from the kiosk demo.

Name	MIDI Offset		Sound	Description
	Rev. 0	Rev. 1
Lesson1	0x00AA9F2C	0x00AA9EFC		Combined versions of Remix 1, Remix 2, and Remix 4. "Lesson" might refer to the dance lessons the development team took during the development of Rhythm Tengoku, of which these song were originally used for. Curiously, a small part of Lesson1 is used by the game in both Remix 1 and Remix 7, as well as Remix 7 in the Studio. This is due to the fact that the intro for Remix 1 (the opening bass slide) wasn't split into a separate MIDI file, thus requiring Lesson1 to be played in each instance where the intro is needed.
Lesson2	0x00AB3160	0x00AB3130
Lesson3	0x00AB85CC	0x00AB859C
L1_pat04	0x00ABF614	0x00ABF5E4		Several unused segments of Remix 1. L1_pat04, L1_pat07, and L1_pat08 are used in Dance Lesson 1.
L1_pat07	0x00AC10C0	0x00AC1090
L1_pat08	0x00AC1B7C	0x00AC1B4C

L2_pat02	0x00AC8190	0x00AC8160		Several unused segments of Remix 2.
L2_pat03	0x00AC8AD0	0x00AC8AA0
L2_pat04	0x00AC9040	0x00AC9010
L2_pat05	0x00AC95E0	0x00AC95B0
L2_pat06	0x00AC9BB0	0x00AC9B80

L2_pat08	0x00ACA7AC	0x00ACA77C

L2_pat13	0x00ACC230	0x00ACC200
L2_pat15	0x00ACD028	0x00ACCFF8
L3_C32_no_swing	0x00ACEBB0	0x00ACEB80		A few unused segments of Remix 4.
L3_C33	0x00ACF73C	0x00ACF70C
L3_C34	0x00AD01B4	0x00AD0184
s_emanikanto_bgm_loop	0x00AFF360	0x00AFF330		A looping variant of the music for Bouncy Road.
s_toss_bgm_end	0x00B20ABC	0x00B20A8C		It would seem that the music for Toss Boys was to originally be internally handled differently, with the game's song being split between distinct looping and ending segments. The final game's music just uses a singular MIDI file, s_toss_bgm.
s_toss_bgm_loop	0x00B20F08	0x00B20ED8
s_menu_kettei0	0x00B39A94	0x00B39A64		Unused menu sound effects for selecting and canceling/backing out of a selection.
s_menu_kettei3	0x00B39D08	0x00B39CD8
s_menu_cancel1	0x00B39D84	0x00B39D54
s_tran_jump	0x00B3BCC0	0x00B3BC90		Voice clips of an announcer giving different commands, such as to jump and transform, meant for Tram to Poline.
s_tran_henge	0x00B3BD0C	0x00B3BCDC
s_tran_seino	0x00B3BD58	0x00B3BD28
s_tran_hensin	0x00B3BDA4	0x00B3BD74

s_toss_red_yelw2	0x00B3C16C	0x00B3C13C
s_toss_red_yelw3	0x00B3C1E0	0x00B3C1B0
s_toss_red_red	0x00B3C254	0x00B3C224
s_toss_red_break	0x00B3C2FC	0x00B3C2CC

s_toss_yelw_red3	0x00B3C850	0x00B3C820
s_toss_yelw_blue3	0x00B3C9B8	0x00B33988
s_shuji_tame	0x00B3CD78	0x00B3CD48		A voice clip of the calligrapher from Power Calligraphy grunting.
s_mario1	0x00B3CEB4	0x00B3CE84		Various copies of the "Japanese" style practice music, all with filenames that make references to Mario. s_mario1_2 and s_mario2_4 are notable in that they add unique melodies to the music, unheard of elsewhere. s_mario1 and s_mario1_2 are duplicates that play at half tempo, but otherwise sound the same.
s_mario1_2	0x00B3D2C4	0x00B3D294
s_mario2_4	0x00B3D744	0x00B3D714
s_mario_melo1	0x00B3DBC4	0x00B3DB94		The first few notes of the Super Mario Bros. Ground Theme. Overlaying these with the aforementioned practice music reveals that they fit perfectly with each other. s_mario_melo2 is another half-tempo duplicate.
s_mario_melo2	0x00B3DC38	0x00B3DC08
s_intro_comeon	0x00B51C00	0x00B51BD0		Voice clip and music used in the second unused drum lesson.
s_intro_pat2	0x00B51F98	0x00B51F68
s_intro_pat3	0x00B52328	0x00B522F8
s_guntai_v_zentai2	0x00B596F0	0x00B596C0		Unused voice clips for the Sarge in Marching Orders. Due to its name following the naming convention of voice clips for quick commands, as well as the presence of such a command in an early voice clip set, s_guntai_v_zentai2 is likely supposed to be Sarge's voice clip for a quick attention command, which doesn't exist in any form in the game. s_guntai_v_hidari_muke2, on the other hand, is his voice clip for a quick left-face command, which are only given by the Leader in Marching Orders 2.
s_guntai_v_hidari_muke2	0x00B598B8	0x00B59888
s_datumo_kegire	0x00B686F8	0x00B686C8		An early hair-pluck sound effect for Rhythm Tweezers.
s_virus_hit	0x00B76B70	0x00B76B40		Early hit and barely sound effects for Sick Beats.
s_virus_osii	0x00B76C84	0x00B76C54
s_f_boxing_just_hati_nc	0x00BCB434	0x00BCB404		Multiple unused sound effects for Karate Man. s_f_boxing_just_hati_nc, s_f_boxing_just_light_nc, and s_f_boxing_just_ball_nc are duplicates of the sound effects for hitting a pot, light, and soccer ball with high flow. s_f_boxing_v_fresh is a voice clip of someone saying "fresh", and s_f_boxing_fly_ext is an alternate sound effect for an item getting thrown.
s_f_boxing_just_light_nc	0x00BCB5DC	0x00BCB5AC
s_f_boxing_just_ball_nc	0x00BCB790	0x00BCB760

s_f_boxing_fly_ext	0x00BCCC48	0x00BCCC18
s_block_gotin	0x00B59B78	0x00B59B48		Leftover sounds from a scrapped game known as ブロック (Block).
s_block_walk	0x00B59D3C	0x00B59D0C
s_kawasemi_bgm	0x00B59DAC	0x00B59D7C		Leftover music from a scrapped game known as かわせみ (Kingfisher).
s_kawasemi_frase	0x00B5A564	0x00B5A534
s_metro_count2	0x00B5BF60	0x00B5BF30		Sound effects used in Metronome.
s_metro_hato	0x00B5BFB4	0x00B5BF84
s_rabbit_atama	0x00B62818	0x00B627E8		A weird kick-drum sound effect meant for Bunny Hop.
s_uma_bulu	0x00B63114	0x00B630E4		A few unused sound effects for Uma Machine. s_uma_bulu is a different voice clip for the horse, possibly intended for when you complete a lesson. s_uma_hi_muti appears to be a sound effect of the horse's rider, and s_uma_ng seems to be a miss sound effect, of which there is no in-game equivalent.
s_uma_hi_muti	0x00B63164	0x00B63134
s_uma_ng	0x00B631B4	0x00B63184
s_block2_block	0x00B9B39C	0x00B9B36C		Leftover sound effects from ブロック２ (Block 2), the exciting sequel to Block.

Revision Differences

Somewhere along the line, the ROM for Rhythm Tengoku was updated, introducing few minor changes.

Iai Giri

Rev. 00	Rev. 01

Three stray pixels were removed from the sliced あ in the prologue for Iai Giri.

Remix 5

Rev. 00	Rev. 01

The very last frame of Aka-chan's Remix 5 crouching toss animation was fixed, with the "A" on her shirt being lowercase to match how it appears on the rest of her animations. She never crouch-tosses in the actual remix, however, so why this change was made is unknown.
