    Yup another VWii related post, but this time theres something interesting..

    So I was reading through threads on multiple forum sites (including this site) and found something about a WiiU reading Miis from VWii to transfer them. I decided to corrupt a random mii and add it with MiiInstaller. What I found is actually pretty interesting..

    Heres what I used
    • WiiU (duh)
    • 2GB SD Card (any size bigger than this works as well)
    • Macbook Pro (works with windows. Just need to have a SD Slot)
    • MiiInstaller
    • MiiExtractor
    • Homebrew Channel
    • A corrupt Mii (crashes the WiiU out of VWii)
    • Wii Remote (to get into VWii)
    What I did and what happened. (Long)
    Warning: Spoilers inside!

    The exception sounds like it was handled, which means it's likely not exploitable. Exploitable crashes usually dump data onto the screen, and don't normally switch off the console.

    The Wii Mini would need to be hacked in order to do this in the first place, you know...

    No, ssbb can access the wii remote, I think that it is for save profile data.

    I know that the hackmii installer only runs from SD card, if it were made to run from USB then a hack for wii mini just might be possible


    No SD card I understand, why is internet required to hack a Wii.

    Yes.
    The Error was handled, so this isn't a possible exploit vector.

    Access the Wii remote how? This is the first I've heard of this.

    Saves are stored to the console.

    How do you plan to run it form USB when games don't load data off of USB and there's no file browser on the Wii?

    Internet - you need a MAC address for Letterbomb/Wilbrand.

    there's games that load data off the Wiimote
    what happens if you could exploit that?

    I'm SO glad somebody took my idea since I was too lazy to play with it, congrats on confirming my theory!
    Once I actually get some time on my hands I will play with this more. props.

    I guess this ended, lol. Cool idea, makes me wonder if something else to cause unhandled exception could be put into a mii;-)

    Gambia, The
    Er, I could be wrong, but I think this was tried on the wii...
    http://mariokartcustom.niceboards.org/t468-longer-mii-name

    I don't know if this was tried further (eg, with games), but I doubt it's harmful.

    I suppose the Wii U just prepared for this (perhaps sincerr Ninty want's you to have the possibility to save it to your account)..

    But on the WiiU did it display the full name? Can you use it in a game? Very curious.

    that would be a good test, maybe load the mii from nintendoland as a new character or something

    Do miis import as favorites? If not, you would have to be able to edit the corrupt me to set it as such, otherwise it won't appear in NL's menus.

    Actually your post is what gave me the idea at first! So I decided to do some research on it then try it!
