I don't know if it has any more features than the free version but I was so impressed with the free version I wanted to pay the developer for his work. If you have already installed the free version, this one imports your games library and settings immediately. No time is wasted setting things up again. What it can play and how well it plays is limited by the power of your hardware. I'm using this on a fairly high end Android TV box and it is working great. My Bluetooth controller was immediately mapped as I would want it. You can always remap buttons and sticks to your personal preference. This is certainly a 5 star app. If you find it less than a 5 star rating, your hardware is most likely not up to the task of proper PSP emulation. The application itself does an outstanding job. I would say I am happier with this app purchase than any other thus far. PPSSPP is hands down the best PSP emulator to date.

Incredibly good, but at the moment I'm livid because I've been using this app for years on all sorts of devices and I noticed they added a option to move your main PPSSPP folder on the android at some point, wanted to move it to the top layer of my phone so I could add/edit files on the fly. The app gave me an option to move all the files over, and I selected it! It did not move any files. Instead, it created new empty folders, and deleted all of my data. All of it. Years of game data just gone

Analog stick dead zone is too large with no way to adjust it. Tested with a Xbox one controller, a few 360 controllers, and 2 phone game pads. Not sure how this feature has been left out for so many years, but it really needs it. I like to feather my analog stick in racing games, and it's very hard with this emulator. Absolutely love it aside from that.
