OKAY! So, here's a run down. After following the guides on this lovely site, I managed to install HBC on the Wii U's Wii mode using Smashstack (Needed a copy of Brawl to do this) and everything worked well! Now, everything is fine and dandy for about 2 weeks... And now today, its no longer working. Every time I load Gecko OS 188.8.131.52, it automatically gives me the Exception (DSI) Ocurred then some dump then a bunch of numbers... I don't know if this is because I was trying to make a certain code with use of the code manager? Like making some Evasion +7 2-slot charms for Monster Hunter Tri. I managed to find out WHAT I did wrong and when I finally thought I put in the right code... I started getting this error. Now, idk. Every time I load Gecko OS, I always get this error no matter what I do. I did a search and I see people are saying it is because of the SD card, USB connectors, too many codes on... ETC. I am playing on the Wii U, going to Wii mode. Everything works WELL, nothing is broken can still launch Wii and Wii U games and what not, except for launching Gecko OS.... Currently reformatting my SD card and doing some troubleshooting. But has anyone come across this problem? If so, how did you fix it?
