Checking the version of your PSP (PlayStation Portable) is a simple process that can be useful for troubleshooting purposes or for ensuring that you have the latest firmware installed. Depending on your PSP model, there are a few different ways to check the version.
For PSP models 1000, 2000, and 3000, you can check the version by going to the Settings menu, selecting “System Settings,” and then selecting “System Information.” The version number will be listed next to “System Software Version.”
