http://www.wiihacks.com/recommended-...tem-menus.html

well i installed usb loader using this wad: USBLoaderGXr850.wad, which is suppose to download the full channel.

since the sd card already had the usb loader on it. . .i loaded it from homebrew channel and it work perfectly fine.. . .

but here is the problem upon removing the sd card from the wii and loading it from the nintendo wii main menu a message pops up:

Exception (DSI) occured!
followed by a bunch of letters and numbers

stack dump
followed by a bunch of letters and numbers

Code Dump:

any suggestions please tell me. . . my intention is to load usb loader gx on my wii without sd card. . . please provide links if possible if anything needs to be installed on my wii. . and maybe u should take a closer look at the link i provided in the beginning of this post thanks. . .
