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.

To contribute, see the development page.

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

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.

  • 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

What's new in 0.9.9.1

A few issues have been discovered in the release that need fixing, the Star Ocean fix had a bug and there are some unexpected slowdowns.

Improved ISO File System - Bleach Soul Carnival 2 now in-game (but freeze when in menu)

What's new in 0.9.9

  • More types of framebuffer copies are now handled correctly, fixing a variety of graphical issues, like the sun in Burnout and many more
  • Better savedata compatibility with the real PSP
  • Support for more codecs used by "Custom BGM" and sometimes regular music in games: MP3, AAC
  • PMP video format support
  • Implemented some strange blending modes like ABSDIFF as shaders, fixing the outlines in DBZ Tag Team and more.
  • Emulation of the vrot CPU instruction improved - it caused cracks in FF3 graphics before
  • Many bugfixes around the UI, touch D-pad now works better when scaled large
  • Workaround implemented to support Star Ocean's stencil trickery as efficiently as possible on all platforms
  • Major corrections to module loading and memory management, fixing further games
  • Bulgarian and Thai language translations were contributed
  • Many, many more game fixes and bug fixes

ADHOC SUPPORT (by Igor Calabria)

This is based on coldbird's code: http://code.google.com/p/aemu/ All credit goes to him!

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) :
