Wadaiko Master Arcade Machine is a music and rhythm game and a regional version (Brazil) of Taiko no Tatsujin Momoiro Version, though it is unconfirmed whether it is a Namco export or not.
Aside from the fact that it contains mostly new songs, it has one of the smallest songlists in any arcade version of Taiko no Tatsujin ever, totaling 32 with 10 Ura Onis. There is no network infrastructure and the middle of the cabinet lacks a Banapassport card reader of any kind.
The play instructions and most of the menu interface save for a few details (and song names) is completely translated from Japanese to Brazilian Portuguese, which is the first time Taiko no Tatsujin has been presented in a language other than Japanese since Taiko 12 Asia, and the first non-Asian version of the game since Taiko Drum Master for PlayStation 2.
One oddity stands out in particular: Sampling Masters AYA's Namco Original song, Samba Alegria, is in the Brazilian Pop genre, Ura and all, instead of its normal place.
