the tutorial is here on how to download it and set it up ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2yWKqc2rmHI.html the mod is here github.com/Retro64Mod/Retro64Mod/releases/tag/1.18.2-1.0.9 Mario needs Forge-1.18.2 to work so right here files.minecraftforge.net PLEASE KEEP IN MIND YOU NEED A ROM OF SUPER MARIO 64 ON YOUR COMPUTER FOR THIS TO WORK! I can't link the download for Mario 64 for you due to piracy issues and nintendo unfortunatly, however you can pretty much find the rom anywhere online to download but be careful that you don"t downoad a virus. also you need to watch the full video I linked becuase there are some extra things in the video you need like: Genfiles.exe(extracts Mario's audio files for use ingame so you can hear his sound effects) A copy of Mario 64(go find it it's everywhere) SM64.dll(So that Java edition can read this file and actaully spawn mario/ his controls and keybinds. linked in video I linked) Retro64(I linked it above) Libs64(also linked in video I linked) Controllable(this is optional but Mario is far easier to controlle with a Xbox/PlayStation controller ect) mrcrayfish.com/mods?id=controllable Once all is set up press M on your keyboard to spawn him Press Z to change playermodels ALT key to punch
