• Choose Overrides and save game-specific keybinds.

• This is helpful when managing controller conflicts between different systems or games.

Sensitivity and Dead Zone Adjustment for Analog Controllers

Adjusting sensitivity and dead zones for analog controllers can enhance your gameplay experience. Unfortunately, mGBA doesn’t have built-in settings for this. However, you can explore third-party tools or adjust your controller settings at the system level (e.g., in Windows or through your controller’s software).

Turbo Buttons and Rapid Fire

Turbo buttons (also known as autofire) allow you to rapidly input a button by holding it down. Here’s how to set up a turbo button in RetroArch (which affects mGBA):

• Configure a turbo button globally (as mentioned earlier).

• Adjust turbo settings under Settings > Input > Turbo Fire.

• Experiment with different turbo modes and frequencies to find what works best.

Controller Profiles for Different Games

Starting from mGBA 0.2.0, you can create controller profiles for different games. However, this feature might be more complex than in some other emulators. If you want to set specific bindings for various controllers, consider using RetroArch’s overrides feature.

• If any erroneous inputs are detected, click the “Clear Analog” and “Clear Button” options.

• Save your changes.

Configure Bluetooth Controllers

Configuring Bluetooth controllers requires a few additional steps. Unfortunately, native Bluetooth support in mGBA is limited, but you can work around it:

Pair Your Controller

Follow the usual Bluetooth pairing process to pair your Bluetooth controller with your computer. Ensure that your operating system recognizes the mGBA controller setup.

Third-Party Software

• Use third-party software like DS4Windows (DualShock 4 controllers) or JoyToKey (for various controllers).

• These tools allow you to map your controller buttons to keyboard keys.

• Configure the software to recognize your controller inputs.

Map Controller Buttons

• Open mGBA.

• Go to Tools > Settings > Controllers.
