mpenguin14 has recently added a background changer to his Manilla 2D Customizer, see http://forum.xda-developers.com/showthread.php?t=427392
It currently requires .png files to work, however, I located some VGA Wallpapers collections in .jpeg format which can be resaved in .png format. So finally some color added to our ported Manilla 2D to our Athenas/Advantages in portrait
However, in Landscape the screen is completely blanked out. Does anyone know of a solution for this? I've left a question on the above thread also.
(PS: maybe the answer is that I need to convert the found wallpapers into Landscape although I don't now how to do that!?)
