PSP Basic - How to check your Firmware Version?

Checking your current firmware version is very task. Just follow the screenshot

1. First access to System Setting from your XMB menu



2. Then go down and find System Information



3. Now you can see your firmware already. The example below is my PSP with Custom firmware
version 5.00 M33-6 . Note that the Original Firmware doesn't have the term 'M33'.
