I what to dowuload game form pc to my pspgame so how can i do it pls

Here are the steps to follow:

1) Insert a Memory Stick into the Memory Stick slot in the left side of the PSP. Depending on how many files you want it to hold, you may need to get a larger one than the stick that came with your system.

2) Turn on the PSP.

3) Plug a USB cable into the back of the PSP and into your PC or Mac. The USB cable needs to have a Mini-B connector on one end (this plugs into the PSP), and a standard USB connector on the other (this plugs into the computer).

4) Scroll to the "Settings" icon on the home menu of your PSP.

5) Find the "USB Connection" icon in the "Settings" menu. Press the X button. Your PSP will display the words "USB Mode" and your PC or Mac will recognize it as a USB storage device.

6) Create a folder called "PSP" on the PSP Memory Stick (if there isn't one already) -- it shows up as "Portable Storage Device" or something similar -- (you can use Windows Explorer on a PC, or Finder on a Mac). There should also be a folder called "MP_ROOT" (not inside the "PSP" folder).

7) If they aren't there already, create folders called "PHOTO" and "MUSIC" inside the "PSP" folder. There also should be a folder called "100MNV01" inside the "MP_ROOT" folder.

8) Drag and drop files into the folders just as you would save files in another folder on your computer. Image files go in the "PHOTO" folder, audio files go in the "MUSIC" folder, and video files go in the "100MNV01" folder.

9) Disconnect your PSP by first clicking on "Safely Remove Hardware" on the bottom menu bar of a PC, or by "ejecting" the drive on the Mac (drag the icon into the trash). Then unplug the USB cable and press the circle button to return to the home menu.

This should help you to move those files.
