Include all the code from the bsnes v068 tarball.

Browse Source 
byuu describes the changes since v067:

This release officially introduces the accuracy and performance cores,
alongside the previously-existing compatibility core. The accuracy core
allows the most accurate SNES emulation ever seen, with every last
processor running at the lowest possible clock synchronization level.
The performance core allows slower computers the chance to finally use
bsnes. It is capable of attaining 60fps in standard games even on an
entry-level Intel Atom processor, commonly found in netbooks.

The accuracy core is absolutely not meant for casual gaming at all. It
is meant solely for getting as close to 100% perfection as possible, no
matter the cost to speed. It should only be used for testing,
development or debugging.

The compatibility core is identical to bsnes v067 and earlier, but is
now roughly 10% faster. This is the default and recommended core for
casual gaming.

The performance core contains an entirely new S-CPU core, with
range-tested IRQs; and uses blargg's heavily-optimized S-DSP core
directly. Although there are very minor accuracy tradeoffs to increase
speed, I am confident that the performance core is still more accurate
and compatible than any other SNES emulator. The S-CPU, S-SMP, S-DSP,
SuperFX and SA-1 processors are all clock-based, just as in the accuracy
and compatibility cores; and as always, there are zero game-specific
hacks. Its compatibility is still well above 99%, running even the most
challenging games flawlessly.

If you have held off from using bsnes in the past due to its system
requirements, please give the performance core a try. I think you will
be impressed. I'm also not finished: I believe performance can be
increased even further.

I would also strongly suggest Windows Vista and Windows 7 users to take
advantage of the new XAudio2 driver by OV2. Not only does it give you
a performance boost, it also lowers latency and provides better sound by
way of skipping an API emulation layer.

Changelog:
- Split core into three profiles: accuracy, compatibility and
  performance
- Accuracy core now takes advantage of variable-bitlength integers (eg
  uint24_t)
- Performance core uses a new S-CPU core, written from scratch for speed
- Performance core uses blargg's snes_dsp library for S-DSP emulation
- Binaries are now compiled using GCC 4.5
- Added a workaround in the SA-1 core for a bug in GCC 4.5+
- The clock-based S-PPU renderer has greatly improved OAM emulation;
  fixing Winter Gold and Megalomania rendering issues
- Corrected pseudo-hires color math in the clock-based S-PPU renderer;
  fixing Super Buster Bros backgrounds
- Fixed a clamping bug in the Cx4 16-bit triangle operation [Jonas
  Quinn]; fixing Mega Man X2 "gained weapon" star background effect
- Updated video renderer to properly handle mixed-resolution screens
  with interlace enabled; fixing Air Strike Patrol level briefing screen
- Added mightymo's 2010-08-19 cheat code pack
- Windows port: added XAudio2 output support [OV2]
- Source: major code restructuring; virtual base classes for processor
- cores removed, build system heavily modified, etc.

//RawInput driver
//author: byuu
//this driver utilizes RawInput (WM_INPUT) to capture keyboard and mouse input.
//although this requires WinXP or newer, it is the only way to uniquely identify
//and independently map multiple keyboards and mice. DirectInput merges all
//keyboards and mice into one device per.
//
//as WM_INPUT lacks specific RAWINPUT structures for gamepads, giving only raw
//data, and because DirectInput supports up to 16 joypads, DirectInput is used
//for joypad mapping.
//
//further, Xbox 360 controllers are explicitly detected and supported through
//XInput. this is because under DirectInput, the LT / RT (trigger) buttons are
//merged into a single Z-axis -- making it impossible to detect both buttons
//being pressed at the same time. with XInput, the state of both trigger
//buttons can be read independently.
//
//so in essence, this is actually more of a hybrid driver.

/*
video.glx
author: byuu

last updated: 2010-01-05
Design notes:
SGI's GLX is the X11/Xlib interface to OpenGL.
At the time of this writing, there are three relevant versions of the API: versions 1.2, 1.3 and 1.4.
Version 1.2 was released on March 4th, 1997.
Version 1.3 was released on October 19th, 1998.
Version 1.4 was released on December 16th, 2005.
Despite version 1.3 being roughly ten years old at this time, there are still many modern X11 GLX drivers
that lack full support for the specification. Most notable would be the official video drivers from ATI.
Given this, 1.4 support is pretty much hopeless to target.
Luckily, each version has been designed to be backwards compatible with the previous version. As well,
version 1.2 is wholly sufficient, albeit less convenient, to implement this video module.
Therefore, for the purpose of compatibility, this driver only uses GLX 1.2 or earlier API commands.
As well, it only uses raw Xlib API commands, so that it is compatible with any toolkit.
