Super Samurai Slice/Unused

Rhythm Heaven Megamix
Super Samurai Slice consists of the following versions in Rhythm Heaven Megamix:

Unused Sprites
There is an unused sprite of what appears to be a spaceship in Super Samurai Slice 2. Presumably, The Wandering Samurai would've boarded it instead of Mister Eagle.

Regional Differences
In Rhythm Sesang: The Best+, the characters featured in both games have their traditional Japanese clothing altered to resemble Korean traditional clothing, called "Hanbok". The Wandering Samurai's appearance is taken directly from the Samurai Slice in Rhythm Sesang Wii and Rhythm Sesang: The Best+. Additionally, the castle in which the ladies are kept captive in Super Samurai Slice 2 is also redesigned. There is also a separate cellanim file for the Wario...Where? version of the game, however there is no difference whatsoever.
