This is an unofficial port of Yabause, a Sega Saturn emulator, and is the first for Wii to emulate the complex processes of the Sega Saturn.

Note that the Wii port is in testable status, and won't be officially supported until a later date.

Note that Yabause Team does not support Wii port, please do not ask the Yabause Team about unofficial versions.

Features

  • ISO or CUE file, cue file needs the files listed in cue file. (not support sega original CD, because Wii cannot read CD).
  • Wiimote, Classic, and Game Cube controllers.
  • Front SD/SDHC and USB storage (only FAT).
  • Save/load state.
  • Configure buttons.
  • Save settings.

Installation

Copy the contents in the HBC directory to your SD (including SDHC) card or USB storage.

Copy game ROMs files (.cue with needed files or .iso) to /yabause/games directory.

When there is /yabause directory in both SD card and USB storage, the files in SD card are given to priority.

Optional BIOS:

  • If you want, copy the bios file of the Sega Saturn to /yabause directory as the name bios.bin.
  • Note that the default setting is "Without bios". So you will need to change to "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. However some games freeze with BIOS (e.g. Sega Rally Champ). So "With BIOS" is not almighty.

User guide

How to use

Load this emulator by a loader such as the Homebrew Channel.

Select the "Load ISO/CUE" menu. The game files in the /yabause/games directory are displayed.

Select a game. Then, return to the main menu.

Select the "Start emulation".

Some games need to select the proper cartridge. So, you must select the proper cartridge before start.

Settings

The important settings are as follows.

Bios (With or Without):

  • Default: Without.
  • Some games work only with bios while the other some games freeze with bios.

Decline Number Timing Parameter (2-17):

  • Default: 15.
  • The yabause executes the process of displaying (BlankOUT process) one image per the decline number
  • The higher the number, the faster but some games are unstable (freezing) while another some games, which did not work in the previous yabauses, work only in the lower number (ex. 2-4) but slower.

SCSP Driver (SCSP1 or SCSP2):

  • Default: SCSP2.
  • SCSP1 is old scsp driver. Some games work only with SCSP2 driver.
  • However, the sound quality with SCSP2 seems to be lower than that with SCSP1.

Divide Number for Clock (1-9):

  • Default: 1.
  • For example, Rockman 8 (it seems to be called as Mega Man 8 in the other areas) works at the divide number for clock=7, but very very slow even if you set the Decline Number Timing = 17.

Video Driver (Software driver or Old software driver):

  • Default: Software driver.
  • New software driver is better rendering but slower while old software driver is faster but worse rendering.

Cartridge List

Cartridge type File name
None ""
Action Replay "/yabause/carts/actionreplay.bin"
Backup 4MBits RAM "/yabause/carts/bkram4M.bin"
Backup 8MBits RAM "/yabause/carts/bkram8M.bin"
Backup 16MBits RAM "/yabause/carts/bkram16M.bin"
Backup 32MBits RAM "/yabause/carts/bkram32M.bin"
DRAM 8MBits ""
DRAM 32MBits ""
ROM 16MBits "/yabause/carts/[gameID]_ROM16M.bin"
Japanese Modem ""
  • The above file names cannot be changed.
  • Tested cartridge types are only backup-RAMs and DRAMs.
  • 8MBits = 1MBytes, 32MBits = 4MBytes; So, DRAM 32MBits is the extended 4MBytes RAM Cartridge.
  • The other types cannot be tested.
  • The file name of the internal backup ram is "/yabause/saves/bkram.bin" on one-backup mode or "/yabause/saves/[gameID].bin" on each-backup mode, though it is not cartridge.
