@jor2404 N64 is a heavy emulator, I don't recommend using high resolution textures on an Rpi4. I have an Rpi3 and I understand that although it is possible to play some N64 games on it, the hardware is not powerful enough to deliver optimal performance in all games. Rpi4 runs much better than N64, but still, the hardware is not powerful enough to be considered excellent.

If you want excellent graphics quality and performance on the N64, you will need a more powerful computer than an Rpi4.
