PPSSPP - a fast and portable PSP emulator

Created by Henrik Rydgård

Additional code by many contributors, see the Credits screen

Originally released under the GPL 2.0 (and later) in November 2012

Official website: http://www.ppsspp.org/

No BIOS file required to play, PPSSPP is in many ways a "HLE" emulator.

What's new in 1.2.1

Fixes for some crash-on-shutdown and app switching problems.

What's new in 1.2.0

A major rework of sceAtrac audio decoding, fixing various music hangs and similar issues
Many fixes and workarounds to depth and stencil buffer usage, and also FBO management
Audio reverb support
Combo keys - custom touch buttons that press multiple PSP buttons
5xBR upscaling on GPU (postprocessing effect)
Fix problems with playback of video with mono audio
Performance improvements like multithreaded audio mixing
ARM64 JIT crash bug fixes
GLSL shader cache to reduce stuttering ingame
Support render-to-CLUT functionality that some games use to change colors of various monsters
x86-64 support on Android
Auto-hide on-screen controls after a while of no usage
Fixes to prescale UV speedhack, now seems reliable
Faster ISO RAM cache
New UI for moving around the PSP display on larger screens
Minor UI fixes like better slider controls
Assorted stability fixes (ffmpeg crash, etc)
Volume setting is back
Preparations for supporting more graphics APIs
AdHoc port offset
Support another HD remaster (Sora no Kiseki Kai HD)

What's new in 1.1.1

Fixed new crash in Persona and other games on ARM64, like Galaxy S6
Fixed crashes when trying to launch web browser when not present on Android, like on Android TV
Fix crash in games that used "depal" functionality (OpenGL)
Fixed rounding mode problems in the JITs
Fix crash when loading savestates many times, and savestate compatibility on Android-x86
Fix minor glitch in Ridge Racer

What's new in 1.1

Support for ARM64 on Android, for improved performance on new devices. Has some new optimizations.
Support Android TV, like nVidia Shield TV
Screen rotation on PC, useful for vertical games like Star Soldier
Many minor performance improvements and compatibility bug fixes
GPU emulation fixes like correct depth rounding, fixing text in Phantasy Star
Other graphical fixes like UV rotation
Support savestates for homebrew apps
Simple integrated "Homebrew Store" to download PSP homebrew apps
Minor AdHoc multiplayer improvements. Still many issues left.
Disable a dangerous optimization on ARM, causing walk-through-walls in Tenchu
sceAtrac music compatibility fixes, fixing noise in a few games
Better texture scaling performance
Direct3D closer in features to OpenGL
Works better on BSD operating systems
Savedata management UI

What's new in 1.0.1

Bugfixes like the save state scroll issue, cosmetic issues like overscroll
Some cheat code bugfixes
Adler32 and Mersenne Twister modules added (fixes some obscure games)
Fix for Jak & Daxter slowdown
Graphics hack for Phantasy Star Portable 2 for Direct3D9
Fix compatibility with some PowerVR devices broken since v0.9.5-959-g4998044

What's new in 1.0

Many, many bug fixes in JIT and elsewhere, improving compatibility
Proper fix for Zenfone and related devices
Direct3D 9 supported as a rendering backend on Windows, helps on old GPUs and can be faster than OpenGL in many cases
You can now create specific configs per game
FPU rounding modes much better supported, fixes the Peace Walker boss that was undefeatable. NOTE: This breaks saves in Gods Eater - you must turn off the better rounding, load your save game, turn it on and save.
The JIT now uses SSE on x86, improving speed considerably. This does not affect ARM devices, that's for the next version or two.
Improved audio output code on both Windows and Android, reducing audio latency on Windows and on some Android systems
FFMPEG upgraded, fixed some music hangs ("GHA phase shifts")
Some Ad Hoc improvements, coldbird.net is now default adhoc server. Ad Hoc still unfinished and hard to use.
Graphics fixes: Bezier/spline drawing fixes, vertex position fixes, DanganRonpa on Adreno fixed, flat shading fixed, vertex cache improved, some PowerVR blockiness issues fixed, screen scaling filter added, Google Cardboard support
Simulate UMD speed better, fixing hangs in several games
More Atrac3 fixes, fixing hangs
Somewhat better disk full handling
Fixes to dynamic unloading of code, fixing problems in GEB and TRM 2/3
Updated to SDL2 where applicable (Linux, Mac)
Some new features, like analog/dpad-swap hotkey, graphics hack for Phantasy Star, show last bit of debug log in dev tools, etc

Status

Code is a bit of a mess and it's not fully functional yet, I still need to implement some functions and add a upnp lib(really important for people with routers).

I did test it with some games(emulator <-> real psp with the server running locally) and it's looking good:

Worms Open Warfare: Ran just fine, I was able to play a whole match without problems
Monster Hunter Freedom Unite: Runs fine too. Gathering Hall and embarking on quests works
Dissidia Duodecim 012: Doesn't work. It requires some functions that I haven't implemented yet. Also, it uses a port < 1000 and thats reserved for admin apps on linux, running the emu as sudo "solves" it, but it's far from ideal.
Pacman World Rally: Works too.

Update (Kyhel) :

Now compiles on both Mac OSX and Windows. For more details on how to play and build go to see there http://forums.ppsspp.org/showthread.php?tid=3595&pid=59241#pid59241
Got it tested windows <-> mac osx <-> psp, it works
Monster Hunter 3rd HD works too, as well as God Eater Burst.
