+XMB Dot-art Theme
+====================
+
+
+Most icons are made by "Yoshi-kun", a Japanese author, from his website:
+http://yspixel.jpn.org/icon/index.html
+
+You can find his collection in the src folder, resized to 256x256 to avoid any kind of filtering happenning in the menu.
+
+The other ones are made by Tatsuya79, some are just slightly altered version of Yoshi-kun ones or 
+from various sources.
+
+Ideally they should be drawn in 32x32 pixels then resized to 256x256.
+
+Icons not covered yet are taken from the Monochrome theme.
