Things You'll Need
Instructions
Turn on your PSP and insert your PSP game into its drive. Press the "Select" button and change "USB Mode" to "UMD Disc." Insert your USB connector into the PSP and connect the other end to the computer.
Wait as a window will appear on your computer. The window will show you the contents of the PSP game. Simply right-click the file that ends in .ISO and click "Copy." Paste onto your Desktop.
Unplug your PSP from the computer and press "Select" once more. Change the USB Mode back to Memory Stick. Connect the PSP to the computer once more, again using the USB cable.
Wait as a window pops up that will show you the contents of the PSP memory stick. Open the ISO folder on the PSP memory stick and right-click on the empty space inside the folder. Click "Paste." Wait as your ISO is transferred.
Disconnect your PSP from the computer once the transfer is complete, and remove the PSP game from the drive. Navigate to the PSP game menu where your game will be waiting for you, but this time it will be entirely playable from the memory stick.
