I realize this will only appeal to a very small group of people, but I decided to post it anyway.  As I mentioned in my article about my Master Sword battery indicator, my PSP has a Legend of Zelda theme going.  I know Zelda's a popular series, so I thought others might be interested.  I've put together a Zelda-themed gameboot, opening sound, XMB icon set, font, and the aforementioned battery icon set.  If you want to deck out your PSP Zelda-style, these are the files you need.  A wallpaper is also a must, but there are so many out there that I decided to let you choose; just search Google or something.

Please note that the custom XMB icons do NOT work with 3.10 OE, and you shouldn't use these files unless you know what they're for as well as all the rules of flashing.  Also, I only made the battery indicator and opening sound; the gameboot, icons, and font come from elsewhere.  The font comes from Birdman's font pack, the gameboot comes from shizzy's gameboot pack (keep in mind that I don't know whether Birdman and Shizzy actually made them themselves), and the XMB icons come from a forum thread I found in a Google search devoted to XMB icons.

Anyway, get the pack here: http://www.filefactory.com/file/9d6fe0/
I don't have any pictures right now, but I will update this when I do.
