On 4840 I added dynamic tuning (which may have slight negative effect on stability) to adapt to different iterations/sec of different systems, but I didn't like this system too much. On 4840 I also made a small change which, I now understand, factors out the differences between systems in this regard, essentially making dynamic tuning not required anymore. So now dynamic tuning is disabled.
If you enable the SPU2X messages (and the overrun messages), you would see log messages similar to this:
buffers: 44 ms ( 89%), tempo: 1.000000, comp: 1.000, iters: 764, (N-IPS:750 -> avg:50, minokc:50, div:100)
If the iters value (764 at this example) on your system when running at 100% speed (50/60fps) is higher than 1000 or lower than 500, then please comment here and post few of the log lines.

I'm not fully happy with it, as it's a bit complicated for my taste, so feedback about how it performs will be appreciated.

The problem as I understood is is incomplete COLCLAMP support.
Thanks to sudo for the hack :)
(Unfortunately we couldn't find out more about why these FMV also *all* flicker.)

- Fixed a bug with mVU's ESIN implementation. This finally fixes the flower-petal bug in Radiata Stories (and hopefully the clouds-bug in VP2 but havn't tested). Rama and I have wanted to fix this for a long time, but never knew the problem :p
- Improved implementation of some undefined behavior that happens on branches to take into account pipeline stalls.
gif / vif:
- Added some logging code that parses gif packets. It can be enabled by the PRINT_GIF_PACKET macro in Gif.h
- Deleted some old gif code.
- On ReadFIFO_VIF1() clear the out-reg to prevent uninitialized results in case GSreadFIFO() doesn't modify it...
- Create a fallback for GSreadFIFO2() so that its always defined (as long as the plugin implements GSreadFIFO())
pcsx2:
- Organized the virtual folders in vs2008 a bit...
Note: vs2010 and Linux builds need to be modified to add Gif_Logger.cpp and delete GIFpath.cpp

1. Much better behavior at extreme low/high FPS (less skips/lower latency).
2. As a result, I was able to reduce internal latency by 50% (50ms config now equals 100ms before).
Recommended latency config for stretcher: 100ms.
For rhythm games, if your FPS is very stable, I recommend 50ms.

Summary of changes...
Fixed menus and HUD for Spyro: A New Beginning and Spyro: the Eternal Night.
Fixed missing dialogs and reduced the VRam usage a bit for Tales of Legendia ("8-bit textures" help a bit more with Vram/speed). Should be playable now in hardware mode. Thanks to rama for figuring it could be hackfixed this way and the initial patch :)
Half-screen fixes for Ty the Tasmanian Tiger 2, X-men Origins: Wolverine, Call of Duty: World at War - Final Fronts.
Modified the Star Wars: Force Unleashed hackfix a bit, shouldn't have the see-thru objects anymore.
Also modified the Metal Gear Solid 3 and Gran Turismo 4 hackfixes as they needed different skip values for each region (PAL/NTSC). Thanx to avih for the region code... and the free C/C++ lessons :P
The hackfix for Sly 3 was still showing stripes for 3-D and two-player modes, fixed for NTSC version now and hopefully works for PAL one too.
Couple GameDB updates after the gif rewrite.

(they were crashing with the new Gif rewrite... shouldn't anymore)
Although Jake had added the new "GSgifTransfer" callback to these plugins in the past, he forgot to modify the .def files so pcsx2 can actually use them :p

this should be the only time that an explicit flushing is needed.
doing it this way should be faster than flushing every incomplete gs packet like r4829 was doing...
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@4831 96395faa-99c1-11dd-bbfe-3dabce05a288
fixes Bleach bankai problem, and probably other games (wizardry/growlancer 3) but haven't tested...
Also removed a vif FlushA hack that used to be needed for tekken 4/gitaroo man but not anymore...
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@4829 96395faa-99c1-11dd-bbfe-3dabce05a288
some bits were kept for reference and should be deleted in the future (along with the entire GIFpath.cpp)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@4823 96395faa-99c1-11dd-bbfe-3dabce05a288
Pcsx2 now has a gifUnit class which acts like the ps2's gif and executes a single gif transfer at a time (and performs path arbitration according to priority and path3 slicing).
This new code is generally a speedup for most games. Particularly VU heavy games like GoW.
This revision breaks old saved state compatibility so don't update if you wish to keep playing with your old saved states.
Leave comments if this revision fixes or breaks anything...
Message to GS Plugin authors:
This new code now uses only 1 gif callback to transfer data to the gs plugin (GSgifTransfer).
pcsx2 also is garaunteed to send full GS primitives to the plugin. So you don't have to account for partial-transfers anymore.
Thanks goes out to shadowlady who tested around 500 games for me :D
Note 1: The old gif code is still in this revision, and can be enabled by the USE_OLD_GIF macro. The old code will be deleted soon.
Note 2: This revision also enables assertion dialogs in devel builds, and changed a lot of assume cases into assertions.

Should prevent erratic tempo variations near 100% speeds (compared to the previous implementation), and generally allow much lower latencies while keeping the audio stable (on all audio systems).
E.g. my tests show that at 70ms latency it can properly handle sharp speed variance of 50%-100%. If your game generally doesn't get slower than 70% speed, 50ms latency would probably be fine.
Note that on extreme scenarios (e.g. extreme sharp drops in speed) it doesn't try to keep the audio continues at all costs. If your game exhibits such behavior (audible clicks, etc), increasing the latency a bit at the config would help.
Comments on actual performance/quality on different systems would be greatly appreciated.

Adding an option for the de-alias filter implemented in r4118,
currently overemphasizes the highs so it's disabled by default
but I like it for some games :P

* use the standard 3 step flow: cmake, make, make install
* Remove L10N_PORTABLE option, superseeded by PACKAGE_MODE
* Extend PACKAGE_MODE to select the install directory (FHS or local bin)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@4805 96395faa-99c1-11dd-bbfe-3dabce05a288
Should be a small boost in fps everywhere and otherwise likely not change anything.
