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:

support saving settings
support configuring buttons
some optimizations (a little fast)
scroll display of long file name
some minor fixes and changes
