Gamecube/Wii games installed with WUP Blank Screen

I had similar problem.

I read somewhere that you need External HDD with external source of power (not y-cable).
- I did not try this method yet.
Or
You can inject Wii game in WiiU internal memeory. Though some games might not work, for me Pikmin is not working.
- I did this and confirmed that some games work.

 

we got the same problem, as Mattkimura said, there is a option that we can play GCN games via nintendont with Gamepad.
by runnning nintendont via vWII but with gamepad


in this method,
i assume you have , Mocha
i assume you have soft mod your vwii channel
i assume that you can access Homebrew channel in vwii
i assume you have nintendont in vWII

steps
1. run mocha
2. install HBC homebrew channel on WII U via WUP Installer GX,(this will allow you to go HBC with gamepad support)
3, once in HBC launch your WAD manager.
4. install Homebrew.Channel.-.OHBC.wad
5. exit and restart

in this steps you can run HBC via wii without probems
1.run mocha
2. run HBC channel
3. once in HBC exit out and you need to go back to WII U
4. run again Mocha
5. run your GCN injects


let me know how it turns out

 

I had the same issue. Either install to NAND or use a usb flash drive. My HDD would not play games installed onto the HDD. Possibly cuts power during the cycle to VWii mode. You can try external power.

 

Did the inject to GameCube USB or nand work for you?

 

Only NAND or usb flash. Usb hdd didn't work for GC and Wii games.
