How to play Wii backups from a usb drive with no modchip?

I have a wii and I have installed the homebrew channel. I have formatted my USB drive to FAT32 and have use the USB loader to rip my games and play them. I want to use the USB drive to load the "USB Loader" either through homebrew channel or preferably through a channel forwarder. This last part, I have not been able to accomplish. I get errors when I actually load the games this way and the games fail. Please help. I can give more info if you need it.
