  • menu_driver: Specifies the user interface driver RetroArch should use. Options include «rgui» (RetroArch’s default UI), «xmb» (a PlayStation-inspired UI), and «ozone» (a modern, minimalistic UI). Experiment with different options to find the interface that suits your preferences.

Choose the resampler that strikes the right balance between audio fidelity and performance for your system.
