Yea there are many. The ones I kno and like are irsmp3 thing. That allows you to play mp3 from ur memory stick in any game and in the VSH w/ the click of a button. There is a quickpower thing that turns off or restarts ur PSP system w/ a click of a button w/out using the power button thing. Just search around on here for some others. So far those are the two I kno of and like.
