hbc isnt in the wii yet to my knowledge. I think the prev. owner used hbc before then uninstalled it the completely wrong way.
You could try to reinstall the menu, only need to download the current firmware of your Wii and IOS from NUS Downloader in WAD format and install them with WAD Manager. Maybe it'll be worked out like this. You need to have HBC installed obviously to do this
Ok, so I tried to do BatHaxx, but I'm kinda stupid because I forgot the Data Management page just doesn't do anything. So I can't transfer it to the Wii. It's weird though, because when I boot up both Galaxy games they load data from the wii, I have Miis saved and they load. So It's just weird to me why it doesn't show it on the data page. The Channel section on the data management page still loads and so does GameCube data. Does the smash hack, twilight, and other lego game hacks require that I transfer SD card memory to the Wii?
Edit: It now boots up in normal mode, but it crashes after a few seconds I tried just doing Letterbomb but fast, but that didn't work. I can open up the letter board, and I had enough time to scroll back 3-4 dates and forward 3-4 dates but I didn't see letterbomb. Can't open settings or boot games in normal mode.
