The site is an Unofficial site, and it's still under construction so don't expect too much. But judging from what it has so far, it looks to be a great site. Containing 30 Official Demos, a Custom made Demo Pack with 26 Demos, and lots of add-ons for the games you already own. It's all free and can be accessed on your PSP if you so desire, because it's been formatted to fit your PSP. That way, you can download it straight to the unit itself without all the hassle of transferring.
