QJ.net: "PSP homebrew developer dav has release a plugin which allows you to modify your PSP's System Information. We all want to personalize our PSPs as much as we can, now don't we?
This isn't the first plugin of this kind either, but we'll take what we can. Besides, this one supports 5.00 and the more recent 5.02 GEN-A. More notes and installation instructions are in the readme."
