A. 1. Adjust button layout: Go to Settings > Controls > Touch Control and reposition the buttons on the right side. Sometimes, moving them slightly can improve responsiveness. 2. Check for screen protector: If you have a screen protector, ensure it is not interfering with touch sensitivity. Consider removing it to test if the buttons become responsive.

B. 3. Restart the app: Close PPSSPP completely and restart it. This can sometimes resolve temporary glitches affecting button responsiveness.
