Default Game Boy Palette:

Navigate to this option to select the palette that your GB Operator will utilize for non-Game Boy Color or Super Game Boy compatible games, or in instances where the model is forced to the original Game Boy setup. This setting ensures that the visual hue and contrast of your beloved games remain true to your recollections.


Hardware Preset Game Boy Palettes:

This setting allows users to engage palettes for Game Boy games that have preset options available on the Game Boy Color or Super Game Boy. Remember to restart your GB Operator after adjusting this setting to apply the changes effectively.


Use Super Game Boy Borders:

For those utilizing the Super Game Boy enhanced games, activating this option will display the original and characteristic Super Game Boy borders, providing that authentic aesthetic that many retro gamers seek. Ensure to restart the system following any modifications in this section.


Color Correction:

Color is paramount in the recreation of the original gaming experience. The color correction setting enables users to adjust output colors, harmonizing them to mirror the display of actual GBA/GBC hardware, thereby ensuring the visual fidelity that retro gamers oftentimes crave.

Interframe Blending:

Interframe blending becomes pivotal when recreating an accurate visual representation of original games on modern displays. Within this setting, gamers find several options:

  • Simple: A straightforward 50:50 mix of the current and preceding frames, providing a consistent blending of visuals.
  • Smart: Intelligently identifies screen flickering and only performs a 50:50 mix on the affected pixels, optimizing visual consistency without over-processing.
  • LCD Ghosting: Mimics the natural LCD response times by amalgamating multiple buffered frames.

Opting for 'Simple' or 'Smart' blending becomes vital for titles like "Wave Race," "Chikyuu Kaihou Gun ZAS," "F-Zero," and those within the "Boktai" series, among others, especially when these games exploit LCD ghosting to achieve particular transparency effects.


Audio Filter:

This option allows users to enable or disable a low pass audio filter. In essence, a low pass filter allows sounds below a specific frequency to pass through while attenuating those above the set frequency. Enabling this feature reduces the 'harshness' of generated audio, a common occurrence in retro games. By applying this filter, users can experience a smoother and less abrasive sound.

 Audio Filter Level:

Once you've chosen to enable the Audio Filter, the next step is to decide the strength of the filter. This is where the 'Audio Filter Level' comes into play.

The Audio Filter Level determines the cut-off frequency of the low pass audio filter. By adjusting this level, users can control how aggressive the filter is. A higher value will attenuate more high frequencies, while a lower value will mean fewer high frequencies are attenuated, giving a milder filter effect. 


The fine-tuning of Video & Audio settings offers a transformative experience for retro gaming enthusiasts. Balancing the charm of yesteryears with today's technological advances, users can customize their gameplay experience, ensuring that every session captures the spirit of classic gaming while embracing modern quality standards.
