The game itself, including the main menu. Voices, audio, fonts, as far I could tell, most of the game itself. It is also possible to install without using a windows installation (except for setting up the japanese stuff).
What does not
The installer crashes, but manually copying the files to the destination directory works. Just installing Japanese fonts does not make the game playable (mojibake appears). The theme video does not play (to the best of my knowledge). However, this is a small issue, since it can be played by mplayer manually.
What was not tested
Most of the game, I went only into the fairly early stages, but most everything works marvelously.
I only managed to get it to work properly by manually copying over files after the installation failed. Also to run the game properly, you need the right fonts/locale installed, and make sure you type LANG=ja_JP.UTF-8 wine shuffle when running the program.

Installation process is flawless and it don't need a howto.
To run correctly the game, your Linux must have east asia language pack.
Some OS have it installed autamaticly, but in some you have to do it by yourself.
Install for e.g. Kinput2 or type kanji/ kana in your file manager and install one's that you are interested in.
After doing the whole stuff, it's time to run the game.
Simply enter to your game folder (for e.g. /.wine/drive_c/Program Files/Navel/Shuffle/) and if your OS is in other language than japanese type (without "" marks): "LANG=ja_JP.UTF-8 wine Shuffle.exe".
It should display japanese writing correctly ;)
For those, who don't speak japanese there is a translation patch.
Their project translates only first two days of the game but they said "We'll do the rest". But it seems that their project is dead. Maybe they will ressurect it but I dunno when.
Anyway have fun with this game... perverts :P Genki de! ;]
Mangagamer is selling an english translation of this game. I have not tested it personally, but I think it would probably work.
