Have someone access to docs from official Vita SDK or have some original games (gr0) and could check this for me? What is a proper size of background inside "$APPDIR/sce_sys/livearea/contents/"? Many homebrew authors using 840x500, some 840x512 but inside the system I have found default one for apps without graphics, used as place holder, and this bg is 840x512. However, when I made screenshot from LiveArea in app screen, it's exactly 840x500. I'm confused.
