The first requirement is a Saturn ROM BIOS image (hence a Sega Saturn). Please don't ask us where to get one.

Execute yabause. The program will open a settings window. The Disc Type setting allows you to be choose whether you'd like to use a real cdrom or a cdrom image of the game you're trying to run. The Cue/Iso File setting allows you to specify the location of your Saturn game's cdrom image. The Drive Letter setting is for you to be able to choose which cdrom drive you want yabause to use when trying to boot a game. The Region setting allows you to choose which region of game you'll be booting. In most cases, it's best to leave it as "Auto-detect". The Bios ROM File setting allows you to specify the location of your Saturn ROM BIOS image. This setting -must- be set to a valid Saturn ROM BIOS in order for yabause to operate correctly. The Backup RAM File setting allows you to specify the location of the Backup RAM file. This file allows yabause to store and load save games. The MPEG ROM File setting allows you to specify the location of a MPEG Card's ROM image. While not necessary, it does allow you to test out the saturn's vcd capabilities. The Cartridge Type setting allows you to be choose which type of external cartridge to emulate. Some carts also require you to supply a rom filename, or a new filename for the emulator to write to. You can enter that information in the field below it. When you're done, just click on the "OK" button. If the bios location was specified correctly, emulation should start and you will see a bit of a brief animation of the saturn logo being formed. Some settings require a restart of the program. Execute yabause. If yabause was compiled with gtk, the program should open a window with a menu. Use the "Open BIOS..." menu entry to choose your bios file. You can also set a cdrom device with the "Open CDROM..." entry. Once the BIOS file is choosen, you can start emulation with the "run" entry.

-b Specify bios file. -c Specify cd device. You can know which file is used as cd device by looking in /etc/fstab. It is commonly something like /dev/hdc or /dev/hdd for IDE devices and /dev/scd0 for SCSI devices. -i Specify iso file.
