Debug Menu

A debug menu is a user interface implemented in a video game that allows the user to view and/or manipulate the program's internal state for the purpose of debugging. Debug menus are used during software development for ease of testing and are usually made inaccessible or otherwise hidden from the end user. They are often of interest to video game players as they can be used to cheat, access unused content, or change the game configuration beyond what is normally allowed.

Rhythm Tengoku

Rhythm Tengoku and Rhythm Tengoku Taikenhan contain a debug menu known as the Sequence Test (シーケンス テスト^?, Shīkensu Tesuto), which allows the user to access virtually every part of the game, including some sequences which go unused. Despite this, there are still unused sequences which are not accessable through Sequence Test. The sequences are generally in reverse order to how they are stored in the rom.

Completing a Rhythm Game or pausing and quitting returns to the Sequence Test menu rather than continuing to the epilogue or Game Select. Pressing Select to exit out of Drum Lessons or Toys leads to an unused version of the results screen, which crashes upon attempting to show a comment. This screen can be accessed directly from this menu as "R-IQ (Result 2)".

Various sequences related to Rhythm Tengoku's menus, title screen, etc. are prefixed with "R-IQ", an early name for the game. Oddly, "R-IQ (Counselor)" appears twice.

Rhythm Heaven Fever

An unnamed debug menu can be found in Rhythm Heaven Fever. In all versions, the menu is written in Japanese. Attempting to return to the menu (through a pause and quit or by finishing a game) softlocks the game. A few unused sequences can be found here as well.

The entry for Seika Relay was removed in the international releases, changing the number for all entries following it. The entries for Basket, Chameleon and Kaeru Tobi lead to unused test sequences for the games in question. They only appear in Endless Remix in normal gameplay.

In Rhythm Sesang Wii, while the menu is still written in Japanese, the font is different, and some entries have slightly different names (primarily removing kanji characters and spelling the words out in katakana instead). １人用 (1-Ri-Yo^?, One Player) and ２人用 (2-Ri-Yo^?, Two Player) are also consistently spelled "１Ｐ" and "２Ｐ" instead.

To the right of the menu is a field for <Operation Explanation, Comment> (＜操作説明、コメント＞^?, <Sōsa Setsumei, Komento >), which is only used by the Game Menu and Error Screen entries.

The first entry, Game Menu, has the following debug features:
