Since I now own a 2.0 unit (didnt have much choice, it was originally a 1.51 firmware), I decided to put the included web browser to use. Grab the source of PSPong, remove yahoo ads and post somewhere your psp browser can access and have fun with this very old classic. Hide the browser UI and use the analog stick to move the paddle. Yes its choppy at times, the ai sucks, and the psp's browser is not well suited for lots of moving things.
You are welcome to grab the source and modify as you please, this was just a 'test' to see what the psp's browser was capable of. Feel free to modify, distribute, I really dont care.
And dont ask for "ooo can you add this" requests..I spent an hour on that page and thats all I'm spending on it =)
