I do exactly like the tutorial but I receive this error: It happened when I repacked the banner.bin to the 0000000.app. (I didn't forget any step. Especially 6.3. Under "U8 type" (Tipo de U8) select "U8 file signed with MD5" (Archivo U8 firmado con MD5) I was trying to change the banner of Zelda Ocarina of Time, and I couldn't continue. I tried with TV Showking WiiWare but still received same error.
