Can u download psp games thru file sharing programs like limewire or ares??

YES!!!!!!!!!!!!!!!! ofcourse you can .all you have to do is plug in a usb cable into your computer and go to lime wire and search what you want in all files. then when its done loading, bring it to your desktop and open a file for your psp but first, go to settings on your psp and click usb connection. then put what you want it the file. then you have it on your psp if it is in the file.
