Homebrew can be a little confusing and intimidating. So, I guess it's a little understandable when tons of confused people write comments in the blog, having absolutely no idea what the latest libtiff exploit does. Sure, they could've read the article, or even the helpful comments, but remember: I'm at your service. While I could explain again that the Hello World demo is just a demonstration of the potential of homebrew running on 2.0+ PSPs, I'll let this cosplaying pirate from PSP Hacking 101 explain it all. Arg, everybody likes pirates, matey!
