1) What is the FIFO? The fifo is a ring queue for write (CPU) and read (GPU) the graphics commands.
2) What is the Brakpoints? The breakpoint is the FIFO mark to allow parallel work (CPU-GPU) When the GPU reached the breakpoint must stop read immediately until this Breakpoint will be removed for the CPU.
3) What is an overflow? The CPU write all room FIFO possible, and like a ring overwrite commands not processed yet.
4) ¿Why you have an overflow? In theory should not have an overflow never because the fifo has another mark (High Watermark) When the CPU Write reach this mark raise a CP interruption and the FIFO CPU WRITES should stop write until distance between READ POINTER AND WRITE POINTER will be equal to another mark (LO Watemark to prevent and overflow.
5) ¡So if impossible why you have overflows? Simple, the CP interruption is processed later and the Overflow happens. (there is a lot of theories about this)
6) ¿Why is no so simple like when CPU WRITE POINTER is near to the end of the FIFO only process pending graphics command?
Because when this happens sometimes we are in BREAKPOINT and is IMPOSIBLE process the graphics commands.
- This HACK process the pending data when CPU WRITE POINTER is 32 bytes before the end of the fifo, and if there is a Breakpoint force the situation to process the commands and prevent an overflown.
In theory you have not see "FIFO is overflown by GatherPipe nCPU thread is too fast!" anymore. But if you have a hang in game where you had this please read the NOTICE LOG in user\logs, I've added this message "FIFO is almost in overflown, BreakPoint" when the hack is activated. (I will delete this message very soon)
Good Luck!! PD: Shuffle sorry for the large commit description :P

Fixes issue 3703.
Note that HLE wiimote activation is currently a little broken, so to
use multiple wiimotes you need to open the wiimote configuration window,
refresh (connect to) the real wiimotes, start the emulation and then
select Connect Wiimote 2/3/4 from the Tools menu or with hotkeys.

wiimote bd's are now read from (or added to if < 4 exist) SysConf
in theory you should be able to use any valid sysconf file now,
but i would advise against using a dolphin edited SysConf on a wii

- Clear alpha channel to 0xFF instead of 0x00 whenever we (re-)create the EFB texture
- Disable color/alpha channels whenever the actual EFB format doesn't use them
Fixes issue 2826.
Fixes issue 1879.
Please check if issue 3014 is fixed now, as well as any other games which might have broken due to ClearScreen changes.
For what it's worth, Super Mario Sunshine still shows a small glitch even with these changes.

* change File::GetSize to fetch the size directly from the open file instead
of stat'ing it when challed with a FILE*
* use changed File::GetSize(FILE *f) instead of calling with file name in two
places
* remove "seek_pos % file_size" hack for ZTP, so one can seek to the end of
file again. Please check Zelda: Twilight Princess for regressions
* return error codes when reading or writing from/to a file
A lot of those changes are from j4ck.fr0st, so kudos to him.
I did not change the file open mode for ISFS_OPEN_WRITE to "wb". While that
would probably be more correct, it says in the comment that it might affect
Mario Kart Wii. I would prefer somebody with that game try that change
locally first.
Please check your games for regressions (or even improvement). Some games that
may be affected are Zelda - Twilight Princess and Metroid Prime 3.

* Added 21 Arithmetic instructions to the JIT
* Used the DSPAnalyser to identify arithmetic/multiplier instructions that precede a conditional branch. This allows the JIT to skip updating the SR when nothing would read from it. Marked all arithmetic/multiplier instructions in the DSPTable for this purpose.
* Converted CheckExternalInterrupt into ASM
* Fixed a couple instructions in DSP Load/Store

skid_au had implemented this in a previous revision and enabled it by default, but it caused glitches if STC wasn't set to "safe" (which kinda defeated the purpose since it slowed down stuff again).
Also renamed the "safe texture cache" to "accurate texture cache", since setting the "safe" texture cache to "safe" sounds kind of silly..

on any other, including "" when a different one is specified through the
POSIX locale environment variables.
This is not normally a problem since these variables are stripped out from
the environment when an application is launched by the Finder. This is not
the case when running the binary directly from the command line, such as
when debugging.
I have temporarily disabled the use of std::locale("") on OS X while I try
to come up with a better solution.
