Yes, this might help, i googled my butt off today, even on the go on my iPhone and on the dunny too, Downloaded gimp (never heard of it) there was an RGB format listed but never allowed me to open, so i chose the load image from raw data option and had all the weird pixels, changed image type to rgb565 and moved the bars and went past something that looked really sweet... MMMM DONUTS! i can only save them as a xcf, or g/b zip, besides the point, i hope someone can make some form of filetype, but something with less hassles Heres that donuts image attached below and heres two screenshots of before and after.
