Worth every penny. I put a custom rom on it to give it a bit of an overclock, remove the bloatware, and provide root access (

The controls emulate an Xbox 360 controller so everything just works out of the box, and the build quality is very good. Has no issue with PS1 or N64 games, and can even do DS and some Dreamcast games with no slowdown. Highly recommended for anyone that wants a portable emulation collection
