The homebrew scene is usually considered a bit of a danger zone, because it often takes some sort of hacking before the console in question will run such home-made software. Jack Tretton, however, has actually praised some of the work of the thriving PSP homebrew crowd.
When asked if Sony would consider adding official homebrew support to PSP, Tretton rather encouragingly said: "I think that is something that is in the works."
"We certainly see some of the stuff that has been done via homebrew, and it's incredibly creative. And I think we'd like to try and tap into that a little bit more."
