Taiko no Tatsujin Momoiro Version is the successor to its color antagonist, Sorairo Version, and is the 4th HDD upgrade to the network-enabled Taiko arcade cabinet. 'Momoiro' refers to the peach-pink theme of the firmware, and may also refer to the girl band Momoiro Clover Z, as the franchise has recently scored a major collaboration with them and even have a new song in their name. In fact, one of the most pushed aspects for this firmware are the collaboration events, ranging from the aforementioned band to the Touhou Music Arrange project and even other rhythm game franchise as well, such as Taito's Groove Coaster and Sega's Maimai series.
All network activities such as Dojo Ranking, Don Challenge and others established in Sorairo Version is carried over here, as with most player data. Two things have received revamps, however; the titles and the costumes. The full-body costumes we used to know as 'kisekae' (着せ替え, changing clothes) is now given the proper name of 'kigurumi' (きぐるみ). In addition to the full-body costumes, players can also opt for a three-part costume made up of head, body and accessory; the new form of 'kisekae'. Some of the full-body costumes from previous firmwares were put into one of these three categories, in addition to more new costumes.
The other thing being split apart are titles; some will be deleted along the way but the majority will be tweaked to fit a new system of being able to piece together two parts to form a single title. Of course, singles titles will still be available for unlock and use. Increased player customization is the name of the game in Momoiro.
Online features are beefed up too, with the Dojo Ranking gaining another fiendish tier above the current highest rank, 10-Dan, and a Rewards Shop added into the online player network Donder Hiroba, marking the first time accumulated Don Points can be spent to buy more costumes (some of which are promotional and time-limited), Taiko sounds, and even new songs.
