Troubleshooting Common Issues

Performance Issues

If your games lag or the gameplay feels choppy, start by lowering the internal resolution in the graphics settings. Disabling effects like anti-aliasing or texture filtering can also help. Close any background apps using CPU or memory. Enabling speed-related options within the emulator settings can improve frame rate and overall performance, especially on older Mac models.

Graphics and Visual Glitches

For games showing strange visuals, black screens, or flickering textures, try switching the rendering mode in the graphics menu. Testing different settings for shaders and resolution often resolves visual bugs. If problems continue, check for updates to your Mac’s graphics drivers and consult user forums for game-specific tweaks.

Controller Setup Problems

If your controller isn’t responding, confirm it’s fully connected and recognized by your Mac. Wired and Bluetooth devices may need different setup steps. Recalibrate the controller through your Mac’s settings, then re-map each button using the input menu inside the emulator. For wireless controllers, low battery or interference can also affect performance.
