Realistic ReShade shader for N64 games, developed on Majora's Mask. It should work fine on other N64 games as well. If using on other N64 games such as Donkey Kong 64, press the "Home" key ingame and disable the DOF or Depth of Field, as it only works correctly on some games.
Both rc5 and rc6 use two ambient occlusion shaders for subtle effect.
