Hid to vpad question

No, Hidtovpad doesn't work with Wii games.

Wii cannot use any controllers except Wiimote and classic controller and sometimes gamepad via injects, and rarely Gamecube controllers with the Gamecube adapter.

 

First you have to make sure the game support the gamepad. Only games that originally supported classic controller will work because the gamepad emulates the classic controller. You can use this compatibility list to see which ones support gamepad

Then when making the inject choose the gamepad/meta tab and change the option under gamepad emulation mode. I usually choose horizontal wii remote emulation but sometimes you might need to choose classic controller emulation. You might just have to experiment.

 

No it's not compatible with anything but Wiimote/nunchuk. It won't work if they didn't add classic controller support for the game which Nintendo didn't.

 

You need to follow instructions and ask question in the appropriate thread https://gbatemp.net/threads/release-wiivc-injector-script-gc-wii-homebrew-support.483577/

 

It takes a LONG time especially if you don't have an SSD hard drive. If it hasn't finished in 2 hours then you might have a problem but give it time.
