Wiiflow works with the USB? Do you have a link to a tutorial?

yes. u are usign wiiscrubber. use an sd card. 1000% times easier

I can't use the SD card because my original disc doesn't work anymore and the SD card doesn't work with USB

Since my old Brawl disc was broken I have to use an Usb and USB Loader GX. I wanted to get back into addng textures so I used wiiscrubber to add the textures to the iso. I used Dolphin to test the textures and all of them work(expect for Jigglypuff with the green hat, I tried changing the texture but it still doesn't work). But when I add the iso to my usb and try to play it on my Wii, it freezes on the stage selection screen. Do anyone know what I am doing wrong?
