Here are all the characters from the GBA game, complete with descriptions and artwork (Japanese-only, but still).
Also, anybody mind explaining where the hell all the artwork from the DS and Wii installments is coming from?
I tried searching for them on Google, but I turn up with only a few of them, scattered on various sites here and there, all with no actual point of origin.
Has anyone ever tried compiling them all together? Is there anywhere I can get artworks of every character from Rhythm Heaven (DS) and Rhythm Heaven Fever (Wii)? If artwork for all of them even exists?
No idea about your question, but it'd make for a great artwork compilation for a game that should get more NA publicity :D --- That is the power of chess. It is a game of secrets in which one must show and never tell.
Most of the official art that is out there (wallpapers, etc) are straight from Nintendo's site, very limited in what they have.
You could do what I'm doing and rip assets from the disc and put them together yourself. Not official by any means, but it's something, and it lets you do crazy stuff like this. http://29.media.tumblr.com/tumblr_m2j4lfZKJ31roaszgo1_1280.png
