When you select a game to play, you’ll notice it immediately goes to a black screen and up top will say press X or M to enter configuration. Press X and it will take you into a configuration screen that will allow you to change plugins. One will allow you to configure a default plugin for all roms in that emulator. With N64, you’ll want to select the option for selecting a plugin for that specific rom. I found that Mario Kart 64 and Super Mario 64, the Mupen64plus-gles2n64 plugin works awesome. Others, like ExciteBike 64 will work better with Mupen64plus-gles2rice.
