Yabause Wii is a Sega Saturn emulator for Wii and is the first of its kind as emulating the complex processes of the Sega Saturn is much harder then it looks and now even harder to run it on the limited hardware of the Wii.

Changes:

add special color calculation mode (blend colors)
thread audio and increase buffer
some minor fixes and changes
