This structure fields should match byte-to-byte the layout of MMIO registers:
it is addressed using the MMIO reg address when doing a CP MMIO read. This was
unfortunately not the case, causing CP reads to be mostly broken with the
software renderer.
Let's talk a bit about this bug. 12nd oldest bug not fixed in Dolphin, it was a
lot of fun to debug and it kept me busy for a while :)
Shoutout to Nintendo for framework.map, without which this could have taken a
lot longer.
Basic debugging using apitrace shows that the heat effect is rendered in an
interesting way:
* An EFB copy texture is created, using the hardware scaler to divide the
texture resolution by two and that way create the blur effect.
* This texture is then warped using indirect texturing: a deformation map is
used to "move" the texture coordinates used to sample the framebuffer copy.

Interestingly, when looking at apitrace, the deformation texture was only 4x4
pixels... weird. It also does not have any feature that you would expect from a
deformation map. Seeing how the heat effect glitches, this deformation texture
being wrong looks like a good candidate for the problem. Let's see how it's
loaded!
By NOPing random calls to GXSetTevIndirect, we find a call that when removed
breaks the effect completely. The parameters used for this call come from the
results of methods of JPAExTexShapeArc objects. 3 different objects go through
this code path, by breaking each one we can notice that the one "controlling"
the heat effect is the one at 0x81575b98.
Following the path of this object a bit more, we can see that it has a method
called "getIndTexId". When this is called, the returned texture ID is used to
index a map and get a JPATextureArc object stored at 0x81577bec.
Nice feature of JPATextureArc: they have a getName method. For this object, it
returns "AK_kagerouInd01". We can probably use that to see how this texture
should look like, by loading it "manually" from the Wind Waker DVD.
Unfortunately I don't know how to do that. Fortunately @Abahbob got me the
texture I wanted in less than 10min after I asked him on Twitter.
AK_kagerouInd01 is a 32x32 texture that really looks like a deformation map:
http://i.imgur.com/0TfZEVj.png . Fun fact: "kagerou" means "heat haze" in JP.
So apparently we're not using the right texture object when rendering! The
GXTexObj that maps to the JPATextureArc is at offset 0x81577bf0 and points to
data at 0x80ed0460, but we're loading texture data from 0x0039d860 instead.
I started to suspect the BP write that loads the texture parameters "did not
work" somehow. Logged that and yes: nothing gets loaded to texture stage 1! ...
but it turns out this is normal, the deformation map is loaded to texture stage
5 (hardcoded in the DOL). Wait, why is the TextureCache trying to load from
texture stage 1 then?!
Because someone sucked at hex.
Fixes issue 2338.
Changes a lot of parsing code which previously was not aware of the notion of
key/value, and operated only with raw lines. Now key/value is the default and
lines are handled as raw only if they do not contain =, or they start with $ or
+ (for Gecko/AR compatibility).
210 commits, more than 2 years of work, one of the most awaited features for
Dolphin.
Thanks a lot to Matthew Parlane and Shawn Hoffman for their work on
wii-network.
There are still a few rough edges, expect some bugs, maybe some regressions.
Please do as much testing as you can.
The code was hitting undefined behavior, causing crashes when starting a Wii
game with Dolphin compiled with gcc >= 4.8.
Might introduce some slight change in the Wiimote activation logic.
Fixes issue 6526.
Use strings internally, use a multimap and std::function for callbacks (instead
of a flat vector + loop over the vector to find the right callback type), fix
coding style issues. Simplify MainAndroid code a bit.
It's not enough to check for the CPUID bit to know if AVX is supported since
AVX requires OS support (new set of registers == more registers to be saved
when context switching). If the OS does not support, the cpuid bit will still
be set but using YMM registers will cause an illegal exception fault.
SDL2.0 removed SDL_HAPTIC_SQUARE because of ABI issues (see comment #7 on issue
6491 by Ryan C. Gordon from the SDL project). It will be reintroduced again in
2.1, so keep the code and #ifdef it away.
This reverts commit cce809ac90.
The code was actually correct: "expr" is never allocated when an error is
returned. This means when the expression parser fails, deleting "expr" means
deleting an uninitialized pointer.
Also keep a PNG version of bin2c'd resources in order to make these kind of
changes easier in the future.
Fixes recent versions of libpng complaining loudly about our images.
GC and Wii games using the AX UCode should now work almost perfectly with DSP
HLE. If you get any issue, make sure the "DSP on dedicated thread" option is
disabled, and try setting framelimit to "Audio".
As a side effect, DSP HLE should not desync anymore (making it usable in
netplay and TAS) with AX games.
