I was finally able to get some WiiWare wads installed on the system using WAD Manager (changed from IOS249 to 250, which worked), but of course, the system is so limited in terms of space. I'll probably have to remove games often to make room for new ones, since I don't yet have a USB drive/HD. Before I do uninstall anything, though, I wanted to ask if I can uninstall using the Wii Menu, or should I find a method via the HBC to remove games from the system?
