It doesn’t really make sense to install custom firmware to “root” PSP to make it run whatever you like. Considering the wide-open nature of its architecture, the PSP remains in popular demand amongst retro gamers. If you unlock the system with the simple prefab boot software located on an SD card, you’ll get an array of retro emulation including the ability to use any file of your choice. There is also a possibility to run PSP ROMS on your portable devices such as smartphone or an iPad. The tutorial about how to download and install PSP Roms and emulators can be found on our website.
