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:

can adjust decline number (2-17): The higher the number, the faster but some games are unstable while anoter some games work only in the lower number (ex. 2-4) but slower.
adjust for PAL monitor mode when libogc detects VI_PAL mode (but I cannot verify this forever)
fix threading
some minor fixes and changes
