im trying to find out images and the values and everything else pretty much.
the ultimate goal of my research of these files is to have everything figured out so that ps3 XMB could be modified just like psp's.

what comes to using the xml values as reference, that would be impossible unfortunately.
only plain values there are are width,height,posX and posY (and posZ) and in most if not all cases, this is always width=0, height=0, posX=0, posY=0 and posZ=0
while the positioning can be changed here, the defaults are loaded into the prx's directly, and the size and location attributes of elements are parentrelative (to a parent i haven't fully figured out yet., it has something to do with a plane the element is loaded on), so there's no clear point of reference to compare anything to anything.

in the example of the clock i made you see on the pic, the image size was defined as 0,0 and changing the image size itself didn't resize the element so it has to be coded elsewhere.
i overwrote them in the xml but left the attributes of the ticks to 0,0,0,0,0 because their positioning and size is relative to the busy icon itself (the clock face)

i don't really know enough yet to draw any solid conclusions... :(
