Soywiz`s Psp Emulator r525

Soywiz's Psp Emulator is a Open Source Sony PlayStation Portable emulator developed with a TDD approach for PC made in C# 4.5. It contains many features, like: fast dynamic recompilation, fast memory access using VirtualAlloc, very fast function cache, clean HLE emulation

Here's changelog:

+ Updated to .NET 4.5 / Mono 3.x.x
+ Reimplemented how the CPU dynarec works:
- Now generates an AST
- Perform some generic optimizations and others related to lwl/lwr that weren't possible before without the AST.
- Adds a new window that allows you to see generated functions as C#, IL, XML or MIPS/disassembler.
- Branch as local optimization
- Native calling/jumping/tail calling with dynamic static fields
- Optimized jalr in fors, caching repeated calls
- syscalls rewritting to normal calls
+ direct memory access
+ VFPU completely reimplemented (now most of the instructions are implemented right)
+ Faster CSO decoding using the native DeflateStream from .NET 4.5
+ Huge Speedup related to GPU rendering:
- Avoid to write video memory into RAM and then read to the display (now it copies the framebuffer into the display window without transferring data)
- Support for scaling the render target (better quality of 3d games and games with bigger 2d textures)
- Removed the requirement of wavoutput.dll and all that stuff, now it uses MaiAt3PlusDecoder
- Added initial support for pmf/h264 videos. It is buggy and doesn't play sound yet. But it is a beggining.
- Much more accurate vsync
+ Lots and lots and zillions of major and minor improvements
