OS4 Important Options

Video Options

• Adjustmentː use the same for helping on adjusting your monitor geometry.
• DynaRes
  • SuperXː games use dynamic horizontal integer scale super resolutions, native vertical resolution, native timing, and properly corrected overscan. It is the recommended mode because avoids real time timing changes for horizontal resolutions (i.e. PSX games).
  • Nativeː games are displayed using both native horizontal and vertical resolutions and native timing. Overscan should be adjusted in your TV/monitor.
• Rotationː rotate the image (unfortunately in-game menus cannot be rotated yet)
• Native CSYNCː this option uses native CSYNC signal generated directly by the Raspberry Pi (will be available in future RGB-Pi compatible models).
• Interlaced Flicker Reductionː apply a bilinear filtering for smoothing the flickering produced in games that use interlaced video modes (slightly reducing the image sharpness).
• LGun Color Replacementː replaces black color on lightgun games for helping the gun sensor to read the TV beam. This is specially intended for arcade games that used fake LGuns (joystick in disguise).
• Video Infoː displays on-screen video information when loading games.

Sound Options

• User Remapsː when active, system default remaps (i.e. arcade remaps) are disabled and user ones are used instead. As an starting point, you could manually copy the standard system remaps from your USB or SD remaps/system folder to remaps/user folder.
• Game Menuː selects the combo button for opening the in game menu (G.Menu). For the game menu to work, it is required that your joystick has a home button and the same was previously mapped.
