Ura Otoko consists of the following versions in Rhythm Tengoku:

Unused Content
An unused test-like game can be accessed through Sequence Test in Rhythm Tengoku, known as Metronome (メトロノーム).

Ura Otoko uses the same graphics as Metronome, meaning there are leftover sprites from it, but they are stored as separate games regardless.

Mr. Upbeat consists of the following versions in Rhythm Heaven Fever:

Unused Content
While there is plenty of dialogue in the game, there are more strings which go unused. While most languages appear to be translations of each other, the text in Rhythm World Wii instead marks it as unused.
