Here is another .CTF I made for my own personal use, that I have now decided to share.
There is not much to explain here.. I shrunk the XMB down, so all columns fit on screen at once. Then added the PS3 wave and sparkles by patpat/Z33... That's it! Simple but sexy.
Then I made a second version of it. If you use the PS3 Style+ theme, then the wave/sparkles will show up over any pic you set as a wallpaper. ;)
I called it "PS3 Style", since it is not a all out PS3 theme, but it is still very similar. Enjoy!
