Happy to hear that......Hello, i have tested it here, it was indeed the conflict between the wii u gamepad receiver and the wifi receiver on the console that caused the crashes.Now i am playing normally with my gamecube pad. Thanks for the help!
For this reason now, from my latest 7.10 in this topic (on the first page), you can find two type of WUP installable WiiU packaging.
The one colored, it's just for Wii U "offline", and this package it's self isolate from the boot.dol from vWii. It means, that the installation package, cannot be upgradable to the new futures versions and cannot download the theme or update the controllers compatiblity and so on, for the problem that we talked above. So, this offline package can read the themes, the updated controllers files or the updated titles ID files from the one that you open in vWii and use the online fitures. But it's nothing related to the boot.dol from vWii. It's like that the boot.dol from vWii it's one Nintendont ant the one from this offline package it's anoter Nintendont.
To solve this, you can find my second package that i made in black/white, this package it's just the true forwarder from the Wii U menu to vWii boot.dol (the one into the vWii homebrew), but it will lose the capability to use the Wii U PAD.
So, you can use the vWii version for updates the files, download themes and so on, and the "Offline" version to play with the Wii U PAD.
Don't try to open the Offline version package and choose to don't use the Wii U PAD for controller, because it will not work anyway; and again, for this reason there are two type of Nintendont-CrisMMMod packages for Wii U.
