How to Configure Global, Emulator-Specific, and Game-Specific Settings?

There are three ways to configure settings.

1. Global Settings

Set in the Game Settings section of the ES menu.

2. Emulator-Specific Settings

Go to:

Game Settings > PER-SYSTEM ADVANCED CONFIGURATION

3. Game-Specific Settings

Hold the A button on a game name and adjust settings in:

Advanced Game Options

Priority: Game-Specific > Emulator-Specific > Global Settings

How to Change the Theme?

Press START, select User Interface Settings, press A, then choose Background Theme and switch to your preferred theme.

How to Adjust Screen Brightness?

Select System Settings and press A.
Choose Brightness.
Use the Left D-pad to decrease brightness.

How to Change Language?

Game Display Settings

Game Display Aspect Ratio Adjustment

1. Open the Aspect Ratio Settings

Press START to open the selection menu, choose Game Settings, then press A.

Scroll down to Game Screen Ratio and select the desired aspect ratio.

2. X/Y (Custom Ratio)

Adjust based on your screen resolution.

For example, a resolution of 640×480 matches a 4:3 ratio.

Setting the display ratio to 4:3 will make most games appear in the corresponding aspect ratio, although some games may still have black borders due to their original design.

3. CORE PROVIDED VIDEO (Original Aspect Ratio)

This setting uses the emulator core's default resolution, ensuring games display in their original aspect ratio without distortion.

If an arcade vertical shooter is displayed horizontally, forcing X/Y (stretched) may severely distort the image.

CORE PROVIDED VIDEO preserves the correct proportions.

Some GB/GBC games may also appear distorted when stretched to full screen.

Note: Some games inherently have black borders and cannot fill the entire screen.

Emulator & Game Settings

How to Switch Emulator Cores?

If a game fails to run, the likely reason is that the emulator core does not support it.

In the game list, select the problematic game and hold the A button for 2 seconds.

Choose the second-to-last option:

Advanced Game Options

Try changing the first option Emulator to a different core.

If none of the cores work, the game ROM may be faulty. Please provide feedback for correction.

How to Set Side B in FDS Games?

Some FDS games require setting Side B to start.

If prompted to set Side B when launching a game:

Press the L1 button to configure Side B.
The game will then load normally.

The selected game will now appear in your Favorites list.
