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

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

• 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)

• 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

• 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

• 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

• 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

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

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.

• 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.
