PPSSPP can run your PSP games on your PC in full HD resolution, and play them on Android too. It can even upscale textures that would otherwise be too blurry as they were made for the small screen of the original PSP.





Here's changelog for 0.9.7 release:
+ Several scheduling and audio fixes, fixing black screens in Yu Gi Oh games among other things.
+ Screen rotation and immersive mode support on Android
+ Large improvements to the software renderer (still not really playable, but looks right more often than not)
+ New VPL allocator and bugfixes, fixing Pangya Golf performance problems.
+ Some mpeg/video playback fixes, fixing Parappa The Rapper and others. Some issues remain.
+ Fix save state bugs causing incompatibility between 32 and 64-bit platforms.
+ Symbol map/debugger improvements
+ Depth buffer copy, fixing Jeanne D'arc. May cause minor slowdowns though, this will be worked around in the future.
+ MsgDialog fixes. Saving fixed in numerous games.
+ Initial multitouch support on Windows 8 for on-screen controls.
