what is there to be brave? lol its clicking a single file and it has no bad benefics, do recall is overclock vwii but you are not atcually overclocking anything, your just not letting the wiiu down clock from wiiu speed to wii speed when entering wii mode all you need is a compatible forwarder with overclock for wiisxrx and teh c2w patcher needs to be runned every time before starting the forwarder, this isnt even a permanent hack.
So basically if you want my files here you go this was what i made for someone that wanted overclocked n64 but you can get the overclock wiiu app from the wiiu files here
first lets get to the forwarder
install on nand the forwarders not to usb

this forwarder was made for wiisxr before it was wiisxrx but it works fine anyway this forwarder will boot the file sd:apps/wiisxr/boot.dol
So you have to rename your wiisxrx ds/fs to wiisxr instead in the apps folder so the forwarder boots it, only rename the folder in the apps not the one in the root of your device, leave that as wiisxrx like normal.
grab the sd root file i posted here, it has n64 stuff if you want too but you can delete it from there and just keep the wiiu folder and place that in the root so you get the overclock, then its easy
