You're supposed to run the modified game via USB Loader, not disk (channel).

i know and i also used the cfg usb loader from this website. but when i launch these games from usb loader the loading screen where it sais "Loading" in the bottom left hand corner just keeps on loading and nothing happens. when i reboot my wii and just try to launch these games with the disk there comes up a system update which i required to lauch these games. when i try then again to launch the games by using cfg usb loader does the program freezes and asks me to reinstall cISO249 to run the program(cfg usb loader). plz help me, maybe i need an other usb loader that runs on another cISO?
