My name is James, from the US. I stopped by to tell you all about the amazing potential a PSP has. First you get one, then you go to this website www.psp-hacks.com. There, look at the tutorials and decide which kind of PSP you have, and put the Custom Firmware on it. Now you can download games in a .CSO file and put them in the ISO folder located on the PSP. If you do this, you can play games for free and give them to all your friends. People on the internet make games that are for the DS re-made in a way for the PSP to use. This makes it so much easier to play anything you like, such as a Final Fantasy game from the PSOne, or even PSP games that have already been released. To do this with a DS, you have to take apart a game you already have, which is so annoying. I've got both and I got to play all my DS games for free on my PSP.
go for the PSP, James
