Moai Doo-Wop/Unused

Rhythm Heaven
Moai Doo-Wop consists of the following versions in Rhythm Heaven:

Regional Differences
The prologue in Rhythm Tengoku Gold looks noticeably less polished compared to the international versions.

Miscellaneous
Normally, each version with an ascociated prologue and epilogue would have the assets for them in subfolders within the versions they belong to. Moai Doo-Wop 2's prologue and epilogue are stored in monomane/ver2 however, which has the graphics for Remix 2 and Remix 9. It is possible they are simply attributed this way to save space, to avoid creating a duplicate for Moai Doo-Wop 2.
