SSF Tutorial

About SSF

This tutorial is to help you with SFF for Windows. From the early 2000s up to 2018, SSF had the crown as the #1 Saturn emulator. The crown was promptly taken away by uoYabause. However, just because SSF was #1 doesn't mean it's a good emulator. Emulation quality is okay. Saturn emulation, in general, has always had a bad reputation for emulating poorly.

Even though uoYabause is #1, it's still buggy and sometimes crashes. SSF may not run games as good, but it's a mature emulator that's far less prone to crash games. So we're not kicking SSF to the curb yet--it's still worth your time.

*If you would like to download SSF, I have it in my emulators page.


SSF is a standalone program so it does not have an install wizard. Installation is simple: just extract SSF from its zip file. Not sure how to extract zip files? Here's a video tutorial showing you how: how to unzip files on Windows.

IMPORTANT! SSF must be placed in a common folder on your computer. I recommend Documents, Downloads, or create a folder on your desktop. If you place SSF somewhere else on your main C drive, then you may be restricting it to read-only access. Doing so prevents SSF from saving anything.

To open SSF, double-click on SSF's EXE

Q: I get a XAudio2Create error!

When you attempt to open SSF, you may receive the following error:

XAudio2Create() error.

File : ./XAudio2.cpp

Line : 219

Function : XAudio2_Initialize

So to resolve this error you need to install the full DirectX package. You can download it here: DirectX End-User Runtime Web Installer (284 KB). This installer promises to install all the legacy files that correct issues such as this.

Q: SSF opens so tiny!

SSF initially opens up in a tiny window

SSF initially opens up small (as shown toward the right). Don't panic! SSF isn't broken. Just wait a few moments. SSF will eventually load into a full window.

Saturn BIOS

Most games require the Saturn BIOS in order to boot or emulate properly. SSF will fool you into thinking it doesn't need the BIOS, but really it does.

Setting up the BIOS

  1. It's best to extract the contents of the BIOS zip files into SSF's folder. It's easier this way.
  2. Click on Option(O) > Option(O), as shown below:
    Entering SSF's BIOS Configuration
  3. You'll arrive at the Options window (shown below). In the “Saturn BIOS” box click the Browse button.
    SSF's Controller Configuration
  4. The “Select Saturn BIOS file” window will pop up, which is this window . Click on “us_100.bin”, then click Open.
  5. Back in the Options window, in the “ST-V BIOS” box click the Browse button.
  6. The “Select STV BIOS file” window will pop up, which is this window . Click on “stv110.bin”, then click Open.
  7. Click OK. A window will pop up with “??????”. SSF is just telling you to close and re-open it for the configured BIOS to take effect. Go ahead and do so.

Setting up the keyboard or gamepad

  1. Click on Option(O) > Option(O), as shown below:
    Entering SSF's Controller Configuration
  2. You'll arrive in the Option window. Click the Controller tab, as shown below:
    SSF's Controller Configuration
  3. To redefine the keys for player 1, click on Redefine where circled above for “Player 1:A”. Follow the prompt and press the keyboard keys or gamepad buttons you want to be assigned.

Booting CD games

Insert your Sega Saturn game into your CD-ROM, then open SSF. That's it! SSF will automatically boot up your game.

Booting ISOs (CD images)

Unfortunately, SSF does not support booting ISO files. However, there are a few things you can do to work around that:

  1. You can use a virtual CD-ROM program to trick SSF into thinking your ISO is a CD in your CD-ROM. I recommend Virtual CloneDrive for that (it's free!). Continue reading below for more information about Virtual CloneDrive and directions.
  2. Option 2 is to burn your ISO as a valid, physical Saturn game. Go here for directions.

Virtual CloneDrive & competitors

Virtual CloneDrive is the friendliest, easiest, and safest virtual CD-ROM program. Its drawback is that it only supports CD images in ISO and BIN format (see below for samples). Virtual CloneDrive does not support “ISO/MP3” or other ISO formats such as NRG, IMG, UIF, DAA, CDI, XBX, B51, BWI, etc.

ISOs supported by Virtual CloneDrive

Well, technically an ISO/MP3 would work. The game just wouldn't have audio when it's running in SSF. The game needs to be a single ISO or BIN/CUE because the audio tracks are packaged into the ISO file.

So what about other virtual CD-ROM programs? Is Virtual CloneDrive your only option? Well, yes and no. If you Google around on this topic, you’ll see people recommending Alcohol 52% Free Edition and Daemon Tools LITE for SSF. Those programs actually work very well. They even support every common ISO format. However, these programs are ridden with adware and malware! I do not recommend them.

If your Saturn game is in an ISO format not supported by Virtual CloneDrive, my recommendation is to try downloading your game from other ROM sites to search for it in ISO or BIN format. Avoid the risk of malware infection from using Alcohol 52% Free Edition or Daemon Tools LITE!

WinCDEmu and MagicDisk are other popular virtual CD-ROM programs. However, they’re not an option because they don’t work with SSF.

Booting CD images with Virtual CloneDrive

  1. Download and install Virtual CloneDrive.
  2. Next, we need to configure CloneDrive in SSF. Open SSF. Click on Option(O) > Option(O), as shown below:
    Entering SSF's CD-ROM drive configuration
  3. Look in the “CD Drive” box. Click the drop-down and choose ELBY CLONEDRIVE, as shown below:
    Selecting the Virtual CloneDrive as the default CD drive
  4. Click OK and close SSF. You'll get a weird “SSF?????” message - ignore it. I'm assuming that message is lost Japanese telling you to restart SSF.
  5. Because you installed CloneDrive, a CD icon should now be in the lower right (next to the time). You find it by clicking on the notch, as shown here . Right-click this icon The Virtual CloneDrive icon, click Drive then Mount, as shown below:
    Selecting the Virtual CloneDrive as the default CD drive
  6. The “Virtual CloneDrive Drive” window will pop up. (Remember, Virtual CloneDrive only supports ISO and BIN files.)
    • If your Saturn ISO is an ISO file: You'll see it in this window . Click on your ISO Saturn game, then click Open.
    • If your Saturn ISO is a BIN file: Click CloneCD/DVD Images in the lower right, then click Other Images - as shown here . Click on your BIN Saturn game (not the CUE sheet), then click Open.
  7. Now open SSF and your Saturn game should automatically be booting up.

Q: I get a black screen when I boot games!

This is tricky. Consider the following:

  • First of all, give SSF a minute or two before you decide that nothing is happening; maybe the game takes a while to boot.
  • Did you setup the BIOS? You should - most games require it.
  • See if the game you're trying to play even works with SSF - check the compatibility list.
  • If this is a Saturn ISO that you downloaded, perhaps it's bad. Try this:
    • I've been told that sometimes bad ISOs can be repaired. Try using CDmage's “Scan for Corruption” feature. Then use “Fix Corruption” to see if it finds anything.
    • Try downloading the game from another site.
  • There's a possibility that your game will run with an older version of SSF. Go to my emulators page and download the zip containing all SSF releases. Try running your game with them to see if it works.
  • If nothing works, then your computer is not compatible with SSF. Sorry, SSF was not designed to run on every machine. SSF requires the following processors:
    SSF requires the processor to have the SSE2 instruction set, so a Pentium 4, Pentium M, Opteron, Athlon 64, Sempron (64bit), Turion 64 or better are necessary to run it.

Q: I get a initializeDirect3D9 error!

Upon booting a game, you might receive this error:

IDirect3DDevice9::CreatePixelShader() error.

File : ./Direct3D9.cpp

Line : 1180

Function : Direct3D9::_initializeDirect3D9

Unlike other SSF errors, this one is actually fixable! You need to make a small edit to “ssf.ini”. So go into SSF's folder and look for ssf.ini. Double-click on it, and it should open up in Notepad. Scroll to the bottom and look for “WindowX” & “WindowY”:

Editing 'WindowX' and 'WindowY' in ssf.ini

As shown above, enter '50' for these attributes. Save and close. Open SSF and the error should be gone.

Full screen mode

Simply press Alt+Enter to bring SSF into full screen. Press Alt+Enter again to exit full screen.

Screen filters

SSF offers two filters for rendering the screen: Scanline and Bilinear Filtering. To enable them:

  1. Click on Option(O) > Option(O), as shown below:
    Entering SSF's screen configuration
  2. Click on the Screen tab, and you'll arrive here:
    Enabling SSF's screen filters

Save states

SSF's save state feature

Save states is a feature that saves the exact spot you are in any game. Here's how it works:

Saving a state

  1. Go to File(F) > State Save(S).
  2. At the top of the screen, SSF will prompt you with “Select Save No. 0-9”:
    SSF's save state feature
    SSF allows you to save up to 10 different save states. For now, press “0” to select the first slot.
  3. That's it! Your state is now saved.

Loading a state

  1. To recall a save state go to File(F) > State Load(L).
  2. At the top of the screen, SSF will prompt you with “Select Save No. 0-9”. Press “0” to load a save from the first slot.

Capturing screen shots

Go to File(F) > Snapshot(C). SSF will dump the screen shot as a bitmap (BMP) into the “Snapshot” folder.

Improving performance

It can't be helped that SSF is a buggy emulator. But, yet there are a few things we can do to improve game performance and maybe even prevent/workaround crashes.

  1. Click on Option(O) > Option(O), as shown below:
    Entering options
  2. Click on the Screen tab. Remove the check from Auto Field Skip, and add checks to VSynch Wait (Window) and VSynch Wait (Fullscreen), as shown below:
    Under the Screen tab, remove the check from Auto Field Skip and add checks to VSynch Wait Window/Fullscreen
  3. Click on the Program 4 tab. Add a check to Deinterlace (Very Slow), as shown below:
    Under the Program 4 tab put a check in Deinterlace
  4. Click on the EZ Setting tab. As shown here I circled two settings:
    • Highest Compatibility - Some games such as “Spiritual Assassin Taromaru” and “Daytona: CE” run best with this setting.
    • Full Compatibility - Set this option for the broadest game compatibility possible with SSF.

General troubleshooting

Sprites in SNK games missing

Character sprites in SNK games may not be appearing. To show them, go to Option(O) > Option(O) and under “Cartridge” select 1MBytes Ram Cartridge, as shown here .

Flickering in FMVs

If FMV sequences have an annoying flicker, go to Option(O) > Option(O) > Program 3 and put a check in Check Cycle Pattern, as shown here .

No sound

If sound is completely gone, well, first check for the obvious and make sure sound is working on your computer. Then try this: go to Option(O) > Option(O) > Program 3 and put a check in Memory Access Wait, as shown here .

Stuttering sound

If you find that sound is stuttering, go to Option(O) > Option(O) > Program 1 and put a check in Scanline Base Timing, as shown here .

Game-specific troubleshooting

You'll find all of the below options in Option(O) > Option(O). There are a lot of games in this list! Try a search in your browser (press Ctrl+F) for the game you want to find.

Finding Saturn games (ISOs)

In my links page, I have some good links to sites where you can download Saturn ISOs. If you want to try to find more sites than what's in my collection of links, just Google around. For example, if you want to download Shining Force III just Google “download shining force iii saturn”.

Q: SSF crashes on start!

This can be tricky because this could be caused by many things.

  1. In most cases, this happens simply because you don't have the latest version of DirectX installed. You can download it here: DirectX End-User Runtime Web Installer (284 KB).
  2. See if the game you're trying to play even works with SSF - check the compatibility list.

Q: SSF crashes mid game and gives CPK error!

At certain points in a game, SSF may suddenly crash and give you this error: “CPK error 0x00000301”. Particularly, this happens in Dragon Force 2 when you select a kingdom. Unfortunately there is no fix for this problem. You can try an older version of SSF to see if the error doesn't occur, but more than likely the game you're playing is not compatible with SSF.

Q: I keep getting disc read errors!

SSF might repeatedly prompt you with disc read errors - even if you're using an ISO with virtual CD-ROM software. There are a few things you can try:

  1. Attempt #1 - Play with the compatibility settings. You find it by going to Option > Option > EZ Setting tab. Maybe try the lowest compatibility setting just to get past the point of the game giving you disc read errors. Then set it back to Full Compatibility until you get disc read errors again. Does this not resolve it? Try the next attempt...
  2. Attempt #2 - Try different versions of SSF. The last time I updated this tutorial, the latest version of SSF was 0.12 beta R4. Avid users of SSF have told me that 0.12 beta R3 is actually more stable than R4. Using R3 seems to be the least prone to give you disc read errors. Does this not resolve it? Try the next attempt...
  3. Attempt #3 - Lastly, I would question your ISO. Maybe it's partially corrupt or in a format that isn't so friendly. So try a different ISO; download the game from somewhere else.

Q: Audio is out of sync!

In some games, you'll encounter out of sync audio, which is very annoying. Games such as “Keio 2”, “Twinkle Star Sprites”, and “Spiritual Assassin Taromaru” are affected by this bug. To resolve this use SSF version 0.11 or older. Go to my emulators page to download older releases of SSF.

Q: SSF isn't saving anything!

If you're using SSF for the first time and you're finding that you have all these problems:

  1. Save states aren't working. You save a state, then when you try to reload it nothing happens.
  2. In an RPG when you save your game at a save point and close/re-open SSF, you find that the save is lost.
  3. Emulator configurations that you changed aren't saved. When you close/re-open SSF, you have to make those configuration changes again.

Then your problem is that you currently have SSF in a read-only location on your computer. You must move SSF to a more common location such as Documents, Downloads, or a folder on your desktop.

Burning Saturn games from ISO

These directions are for burning an ISO or BIN/CUE archive to a CD-R. Note that in order to play CD-R copies on the Sega Saturn system, you need to use the boot trick.

  1. Download & install ImgBurn (it's free). You can download ImgBurn from the ImgBurn homepage.
    *If you have an anti-virus such as AVG, it may flag ImgBurn for containing adware . Don't panic - it does not contain adware! This warning is false. All that ImgBurn does is show you ads during the install wizard (which is why AVG falsely flags it). ImgBurn is 100% safe.
  2. Upon opening ImgBurn, click Write image file to disc, as shown here .
  3. Under “Source” click the folder icon, as shown here . Navigate your computer to where your Saturn ISO or BIN/CUE resides. Select it and click Open, as shown here
  4. Take a look at this picture . Insert the CD-R disc. Upon insertion, you'll see information appear (where indicated in the picture at “1”). Next, make sure your CD drive is selected (it should do it automatically).
  5. Click the icon to burn. Depending on the speed of your CD drive, your game could take maybe 2-10 minutes to finish burning. That's it! Enjoy your fresh copy of a Saturn game.

Copying/Backing up Saturn games

These directions are for duplicating a real Saturn game or a CD-R copy.

  1. Download & install ImgBurn (it's free). You can download ImgBurn from the ImgBurn homepage.
  2. First, you need to rip your Saturn game to an ISO. Open ImgBurn. Click Create image file from disc, as shown here .
  3. Make sure the proper source drive is set in “Source”, then click the Read icon - as shown here .
  4. Ripping your Saturn game will take maybe 20-30 minutes. By default, ImgBurn will toss the BIN file (the ISO) into Documents. Now that you have a BIN/CUE of your game you can follow the burning directions right above. Scroll up to Burning Saturn games from ISO.
