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.
