Yabause Wii is the Wii version of Yabause, a Sega Saturn emulator, and is the first of its kind as emulating the complex processes of the Sega Saturn. The Wii port is not released officially. Some unofficial versions have been released. Note that the Wii port is in alpha status, and won't be officially supported until a later date. You must not ask the Yabause Team about unofficial versions.

Development Status

  • All versions are still experimental.
  • The unofficial r2411 alpha9 version is recommended.
  • 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 the recommended unofficial version can be normally displayed in various resolutions.

How to set up

  1. Copy the contents in the SD_root to your SD or SDHC card.
  2. Copy game ROMs files (.cue with .bin or .iso) to SSROMS directory.

Extra: If you like, you can copy a BIOS file of the Sega Saturn to SSROMS directory as the name "bios.bin". The current version of Yabause Wii can execute games without BIOS.

How to use

  1. Load this emulator by a loader such as the homebrew channel.
  2. Select the "Load ISO/CUE" menu. The game files in the SSROMS directory are displayed.
  3. Select a game. you got to cartridge submenu. Some games need to select the proper cartridge.
  4. Select the proper cartridge, you return to the main menu.
  5. Select the "Start emulation".
