then put your sd card on pc and download the attached zip here
https://www.mediafire.com/file/rqjv4p0y8e8lesw/SD+root.zip/file ,open the folder and then pass all files to your sdcard root exactly like that to your sd card root then open wii64 folder and roms folder and put your spiderman.z64 rom in there
with this file i will give you both regular wii64 and wii64 rice which some work for some games better than others spiderman only on rice tough also give you the vwii overclock file for homebrew launcher when a game run slow on wii64 you can overclock vwii to wiiu speed to do so you first go to homebrew launcher and then start the overclock file called sign_c2w_patcher then you will be back to wiiu menu and then start wii64 or wii64 rice and they will be overclocked, most games dont need overclock tough, spider man shure doesnt need it.
