The whole proceedure is incredibly complex and involves a deep understanding of the whole XMB with icon caching, shadows, registry etc etc.

Honestly, I don't know exactly how it works from any code I've seen and to use the code you need to actually know how the whole system works. The result in Game Categories is the hundreds of hours of research into the XMB design and thousands of lines of RE code.

Iv been reverse engineering game categories for a couple of weeks but its quite hard to keep up with Bubbletune and his weekly releases. If i make any progress i will be sure to post a tutorial on how everything works.

Its to bad there's so much secrecy around the xmb like vlf and game categories. The homebrew community could greatly benefit from there work.

I wouldn't speak of secrecy, but rather keeping it closed source. There's a lot of things to do if you want to, say, add an icon to the XMB. Memory Stick icons are the easiest, but others require a lot more work. Considering that, I think releasing the source will just lead to people leeching of Game Categories instead of providing innovative plugins. I have considered more than once to publish the information I have on this matter, and I might reconsider again. I don't plan on releasing the Game Categories source code, but I might code up some samples on adding icons and release them open sourced.

It would be great, if you could make samples for doing this :-)

Thanks for your reply.
I have writed a homebrew to encrypt/decrypt video files,but I haven't any idea to make a beautiful UI.When I saw the Game Categories,it seems good that add a Memory Stick icons to show my crypted video files,and when you try to play them,you need input password first.
