(I will update the above website. But the site is wiki, anyone 
 can edit it. If I felt inconvenience, I might stop updating.)

#Introduction
This unofficial version is added submenues to the original 
 Yabause by Yabause Team, and is mainly modified about 
 dislaying various resolutions.
Both Ac_K (based on 0.9.7 Yabause) and Markus1981 (based on 
0.9.5 Yabause) versions are very old. 
A lot of people told that Ac_K version did not work well,
 while both Markus1981 and original Yabause versions are
 inconvenient with selecting games. 
Only this version can be normally displayed in various resolutions.
But, this emulator is originated from the great effort of
 "Yabause Team".
So, you should write the name "Yabause Team" as the author
 or creator.
But, note that Yabause Team does not support Wii port.

This set includes the source.
The original sources are available on the following sites.

#How to set up
1) Copy the contens in the HBC to your SD (including SDHC) card or USB storage. 
2) Copy game roms files (.cue with .bin, or .iso) to SSROMS
directory.
Optional) If you want, copy the bios file of the Sega Saturn to 
SSROMS directory as the name "bios.bin" (But, the default setting is "Without bios". So, if you want to use bios, please set the "With bios" in the Settings submenu).
The current version of Yabause Wii can execute games without BIOS.
Some games need the bios file to run normally.
Morover, you can use the bios utilities (catridge management (remove, copy, etc.), etc.), when you set the "Bios only" in the Settings submenu.

When there are game files in both SD card and USB storage, the game files in SD card are given  to priority.

#How to use
Load this emulator by a loader such as the homebrew channel.
At first, select the "Load ISO/CUE" menu.
Then, the game files in the SSROMS directory are displayed.
Second, select a game.
Then, you got to cartridge submenu.
Some games need to select the proper cartridge.
Third, select the proper cartridge.
Then, you return to the main menu.
Finally, select the "Start emulation".
