I've been testing out some hacking things today with Wii U Via the Smash Stack exploit. I can get the HBC installer to come up but it states there aren't any vulnerable IOS. I've tried to get the trucha bug on the console with various apps to no avail. You CAN run .dol files with Multi Mod Manager. Wads won't install as there is no trucha bug to fake sign them, I spose. The Wii U will freeze at times, which will force you to pull the power plug to reboot. This typically happens after trying to run the smash stack twice in one sitting, no matter how long its been it seems. The newest WiiFlow hung at the loading screen then threw up an error booting me back to the menu. Coverfloader black screened. So there ya have it. **UPDATE** I've tried to install various ios via DOP-Mii, and they all fail to install. I have NOT tried to install 20 that was suggested in this thread, but I'd imagine it would fail as well. I haven't tested Riivolution, but if someone gives me a direct tutorial / files needed for a popular Smash Bros Brawl one I'd do it. I have tried Casper and it hangs on a screen that is black with text that states the ios version.
