- This article is about the emulator. For the audio format, see Saturn Sound Format.
SSF is a Windows-based emulator of the Sega Saturn and Sega Titan Video (ST-V, an arcade board very similar to the Saturn). Despite the historical difficulty of emulating the Saturn's rather idiosyncratic and complex architecture, and the fact that SSF is developed by a sole developer (Shima), it has overtaken other Saturn emulators to the point of being able to run the majority of games with few to no issues. It is designed to run game CDs directly, so images must be mounted with a virtual drive program (e.g. Daemon Tools) in order to be played.

Prior versions
The most recent version is usually the best to use, though a few games may work better with previous ones (see compatibility lists). A repository of previous versions (starting from version 0.06 alpha 4) is maintained on the official site. For convenience, those available at the time of writing have been bundled below.
- SSF versions 0.07 beta R1 to 0.12 beta R3 (info) ("SSF versions 006-011.7z" does not exist) (6.02 MB)
- 0.06 alpha 4 is missing due to a virus alert.
Known issues
The emulator has a certain amount of input lag, which can't be reduced to the levels of e.g. Yabause. This can be problematic for games that require fast reaction, such as shooting games. The author acknowledges these input lag issues but and gave reasons for these on the project homepage. He also offers some suggestions to reduce the problem, e.g. use a high spec PC, disable V-sync (emulator settings, causes tearing) and enable "VDP2 RAM write timing".
