Riiski mod give you preloader and CIOSCORP, which allows for almost 100% compatible loading through the disc channel. You don't have to use any launcher to load your backups, or patch your games, or force video mode any more. Also, preloader has alot of benefits, like the hacks.ini file, loading and installing wads without booting into the system menu, and the ability to autoboot into hbc, or any other wad if you'd like. The risk is, if your wii gets shut down during the system menu patching process, or you accidentally delete the systemmenu.dol, your wii is partially bricked.
