There is a great site that has PSP demos and homebrew games for the PSP. Go to http://www.gamecrazy.ca/psp/page.html">http://www.gamecrazy.ca/psp/page.html on your PSP to download games and more. Follow the demo instructions to make sure you set it up correctly on your memory card.

I check the PSP home page for demos all the time. I’m glad to see there are few on this site that I am not familar with and haven’t played.
