Enable Gamma Correction | Enables gamma correction.
Darken mid-tones, Lighten mid-tones, Other Gamma value | Allows you to configure the gamma value to use.
Use video hardware when possible, use video hardware exclusively, use software exclusively | Tells FB Alpha how to apply the gamma correction. Recommended setting is Use video hardware exclusively unless this gives you problems.
Window size | Determines the size of the window when not in fullscreen. Choose between Auto, Single Size, Double Size, Triple Size, Quadruple Size, or Maximise.
Toggle fullscreen mode | Switch to fullscreen.
Auto Switch to Fullscreen after loading | Enabling this option will automatically switch to fullscreen after you load a game from the Game Select Dialog.
Full Screen Resolution | Allows you to set the fullscreen resolution to use. This can be configured independently for hoziontal and vertical games. You can select between Arcade (which attempts to use the games native resolution, Single Size, Double Size, Triple Size, Quadruple Size or you can specify a specific resolution to use.
Fullscreen bitdepth | Allows you to choose between 16-bit, 24-bit and 32-bit colour modes for use in fullscreen.
Choose Fullscreen Monitor | Opens the Choose Monitor for Full Screen dialog.
Automatically detect aspect ratio | If this is enabled FB Alpha will automatically attempt to determine the aspect ratio of your monitor.
Normal CRT, Normal LCD, Widescreen CRT, Widescreen LCD aspect ratio | Select the one that best describes your monitor. This will help to preserve the look of the original game. This option will be selected for you automatically if the Automatically detect aspect ratio item is enabled.
Mirrored vertical alignment | If enabled will mirror the aspect ratio settings for vertical games.
Rotate vertically aligned games | If this option is enabled then vertical games will be rotated by FB Alpha. Only disable this if you want to align your monitor vertically to play vertical games.
Force 60hz refresh rate | This option will force the video to ouput at 60hz. This will help to eliminate tearing but may induce other problems.
Enable Triple Buffering (Fullscreen) | Use a triple buffer in fullscreen.
Enable VSync (Windowed) | Enabling this will help to eliminate tearing in Windowed mode but you may see slightly juttering scrolling.
Enable DWM Sync (Windowed) | Alternate VSync method, for Windows 7 - 10 with slightly better frame timing depending on the system. It is suggested that you use this along with setting your desktop video mode to 60hz to eliminate microstutter issues. The high resolution system timer option under Misc -> Options may also help.
Auto frameskip | This will skip frames in the video output if necessary to keep the game running at fullspeed. This is only necessary for slower computers but it is recommended to leave it on for all computers.

### Basic (DirectDraw 7) Blitter Menu

No Effects | Turns off all effects.
Scanlines | Will turn on a scanline effect.
Scanlines 50% | Will turn on an alternative scanline effect.
Rotate scanlines | If this is enabled then scanlines will be rotated for vertical games.
Force Flip | Forces hardware flipping for games that require it. This is usually detected as an available feature, but due to DirectDraw being old, the support doesn't usually get detected. This option will force the flipping if a game needs it. This is best used with the System Memory Buffering Method. This option will likely force Windows to disable Aero and revert to basic settings, and is therefore recommended for older computers still using Windows XP only. If you are using a version of Windows newer than XP then you should be using the Enhanced or DirectX 9 blitters.
Buffering Method | Choose between Autodetect, Video memory, and System memory. The recommended setting is Autodetect unless this causes you problems.
