需要修改的retroarch.cfg參數 

audio_driver = "sdl"
custom_viewport_height = "240"
custom_viewport_width = "320"
libretro_directory = "/boot/.config/retroarch/cores"
libretro_info_path = "/boot/.config/retroarch/info/"
microphone_driver = ""
rgui_browser_directory = "~/"
video_driver = "sdl"
video_window_auto_height_max = "240"
video_window_auto_width_max = "320"
video_windowed_position_height = "240"
video_windowed_position_width = "320"
