First off, please note that many of the games available for download to PSP are illegal, due to copyright violation.

There are many legal games that you can download, plus game demos, music, screensavers, widgets, and whatnot, but that latest PSP game that costs $50 off the shelf is not legal to download, even though it might be available.

Generally, to download a lot of this stuff you'll need to hack your PSP operating system. It's not hard, but you do need to be carefull or you'll "brick" your PSP (turn it into a brick, eg: useless.) So it's that old grey area. Do we provide the info to run legal 3rd party freeware, knowing that some (or many) will abuse it?

Or do we try to lock it up tight? Sony is constantly upgrading the PSP operating system to disable just these types of hacks.

Sony tends to assume that the only reason people want to hack the PSP is to run stolen/illegal software. Are they right?

If you go to PSP-Monkey.com you'll find complete instructions on how to modify your PSP, plus software and lots of tips. All free. I try assume that people are responsible citizens and won't abuse that power and steal software, so check it out and go ahead and monkey with your PSP. ;)
