Playing Sega Saturn Games on PC

SSF is a emulator designed for emulating sega saturn games. This emulator make it possible that playing sega saturn games on pc. If you want to experience this emulator, you can download from ‘’.

Firstly we will talk about features of SSF.  If we should list them, it will be like this: BIOS file not required, but may improve compatibility in certain casesAll regions (PAL & NTSC) emulated.                                                              

  • Backup memory emulated.           
  • Savestates supported.   
  • Joystick support.  

Can dump screenshots in BMP format, and audio in WAV format. Unoptimized PAL games can be made run at the speed of their NTSC counterpart by setting the “Emulation Speed” lever to 1.20, often without unwanted acceleration of music and sound playback.

Secondky we will explain compatibilty ; New Test System (For versions above 0.09 Beta. I’ve been getting emails from people assuming my new test system is needed to run Saturn emulation. It’s not.   

You could run SSF at full speed on a $400 Dell (the main exception being some of the 3D fighting games running low FPS).                                                               

As far as games running slower on my old system, I could have enabled Frame Skip in SSF to speed them up but then I wouldn’t have had an excuse to upgrade. I specifically built this system to run Crysis at a reasonable frame rate and just happen to use the same system for testing SSF.

Next point we will explain is system requirements: Recommended configuration                          

CPU: Intel Core i7 series                                        

 Intel Core 2 Duo series AMD Phenom II series                                                                                    

AMD Phenom series

Memory: 512MB or above running in Dual Channel mode

Absolute minimum config required for running SSF:                                                      

OS: Windows2000/XP/Vista   Windows 7 (both 32 and 64bit versions) should also work.

If you experience problems under Vista or 7, make sure your drivers are up to date.

CPU: A cpu which has a FPU (Floating Point Unit), supports the TSC (Time Stamp Counter), and supports MMX, SSE and SSE2 instruction sets. Practically, this means any Pentium 4 or Athlon 64, or above. Athlon XP does not have SSE2 instructions and will not run.                                                                                   

RAM: 256MB or above                                                                                            

 Video card: A videocard compatible with DirectX9.0c, capable of drawing textures at the size of 1024×512 and 1024×1024.

This includes any modern videocard or onboard video device.                                                                        

 Sound: A soundcard compatible with DirectX9.0c, and is capable of playing back Stereo PCM streams at 44100Hz sampling rate. Basically any soundcard or onboard audio device.

Esc = quits the emulator

The following keys cannot be modified (for STV mode):

F11 = Test menu

F12 = Service Button
