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

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 sceMpegRingbufferAvailableSize - UFC© Undisputed™ 2010 now playable

 - 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
 
- OpenGL ES 3 detection bug on Xperia devices fixed, graphics work again.
 - More accurate audio mixing and emulation
 - Software rendering and display list performance improvements
 - Workaround for timing issue hanging Crash Tag Team Racing
 - Galician language
 - Built-in ARM disassembler improvements (dev feature)
 - Fix for immersive mode volume key issue on Android Kitkat

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.
