(Do you mean the first __FIVE__ * characters inside the wii-picture file are always AJPGZ?) On the files I extracted the 5th letter is different. You can see a sample here. [[Media:X-wii-picture-sample1.zip]]
:Each block of image data begins with ASCII "QUpQR1"
Actually this is partly true, but only BEFORE you do the base64 decoding. (My sample file actually starts with QUpQR0, but again this is before you do the base64 decoding so there is not much point in documenting that here. :) )
