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.
Watch Nerrel's video about Majora's Mask texture mods to learn more about setting this up if you have issues, use the installer, download reshade and install it as opengl on project64 then overwrite with my files if necessary.
