    A Wii U that is on 5.5.2 can still mod anything within the vWii, so it would definitely be a great idea to use / create an app in the vWii to create exploits on the Wii U itself even past 5.5.2 before the next fix for Homebrew Launcher on loadiine.ovh comes out. This could have something to do with the "Wii U Menu" channel boot.

    lol no.. the vWii doesn't even have access to the WiiU NAND (I think it probably doesn't even know that it's a Wii U)

    That's what the "Wii U Menu" channel on vWii does. It uses a syscall in IOS62 that forces a hard reboot of the system.

    It could be used when using the "Return to Wii U Menu" channel.

    Yes but I believe the boot and reboot operations are different. If we can find out how this function call works, there is possibility for CBCFW

    Hm?

    Oh duh Im idiot! You know in wii u games there are sometimes a button that loads an applet right? How about we manage to redirect the loaded applet to the homebrew launch process? would it work?

    How do you propose to do that on an unhacked 5.5.2 system?

    Maybe but we don't know. And we can't do it since you are on 5.5.2

    But you would need to be able to load homebrew to make the applet redirect in the first place lol.

    I didn't create that. (You probably meant SSBB, not "SSMB".)

    Also, that can be used on an unhacked system because the game reads data off of the SD card without enough verification. That's an entry point.

    5.5.2 closed the only publicly-known entry point for Wii U mode on unhacked systems at the moment.

    As far as I know. Its not possible. Unless you can somehow force the vwii to mount the entire wiiu side, but if its hidden at boot of vwii then its impossible. The only chance (and proably would still be impossible) is to write a ENTIRELY custom IOS. But again. Its probably impossible
