Power Calligraphy/Unused

Rhythm Tengoku
Rhythm o Shuji consists of the following versions in Rhythm Tengoku:

Unused Content
There is an unused gameplay history screen in Rhythm Tengoku which can be accessed through Sequence Test, which lists all the games and things in the Omaku Corner, the average score the player currently has (using a numbering system from 0 to 1000 which is hidden from the player in normal gameplay), and the amount of plays. Among the games is a string reading リズムお習字 ２ (Rhythm o Shuji 2).

In the game's RAM, there is an area which keeps track of the player's Rank on each Rhythm Game, with the one for arrange versions being directly after the equivalent long version. There is a byte just after the one for Rhythm o Shuji, reserved for Rhythm o Shuji 2. Changing it does affect the rank in the gameplay history screen, but it has no effect on the Game Select. There is no playable data of this game.

Rhythm Heaven Fever
Power Calligraphy consists of the following versions in Rhythm Heaven Fever:

Regional Differences
The kanji 完 (Kan) was translated in the localized versions of Rhythm Heaven Fever, but was left in its original Japanese form in all versions of Rhythm Heaven Megamix.

Regional Differences
In Rhythm Sesang: The Best+, the same changes from Rhythm World Wii apply. Interestingly, the Official Game Trailer doesn't use the localized artwork for this game.
