Things You'll Need
Instructions
Put the memory stick into the computer.
Use a mini USB cable to connect the PSP to your computer if you do not have a reader for the memory stick. Set your PSP to "Connection" mode, found in your system settings on the PSP menu.
Go to the PSP-Hacks website (see Resources.)
Click on "PSP Downloads" on the main page, then at the next window, click on "PSP-Homebrew."
Browse through the different homebrew categories and download programs that interest you.
Transfer the downloaded files to your PSP and place them in the "Games" folder. (If there isn't a "Games" folder, create one and put the files there.)
