PPSSPP is written in C++, and translates PSP CPU instructions directly into optimized x86, x64 and ARM machine code, using an efficient JIT compiler.

PPSSPP can thus run on quite low-spec hardware, including stronger Android phones and tablets, as long as there's support for OpenGL ES 2.0.

System requirements: 

SDL2(optionally Qt for a full GUI)


very nice, playing kingdom hearts here in 720p on an old intel celeron with integrated hd graphics
