How would you like to change change your PSP's system version number, minus the flash? Well, JumpR's new homebrew application - Flashless Version Changer v2 - allows you to do precisely that in system information with the Slim version of Sony's handheld as well.

Before you do that, however, there are a couple of things that you should know, according to JumpR:

1. It doesn't allow you to play any new games or use any new features
2. This application is only compatible with firmware 3.90 M33, though JumpR may add other firmware versions later.

With those in mind, enable the plugin and create a vchanger.txt in the root, which you may fill with the version you want. JumpR noted that "it doesn't need to be a numeric version, you can use anything you want, even complete words. But the maximum it can go is 10 bytes, not any longer."
