The WiiVC route is only possible on dolphin, which isn't legal to submit runs with. You can run a route that works on project 64 though, but it's a bit slower. I recommend joining the discord server to get help with it, but it involves doing light node SRM just like the wii route, but going into the deku tree instead, taking you to the credits.
