Fragment coordinates always have a 0.5 offset from a whole integer, as
that's where the pixel center is on modern GPUs. Therefore, we want to
always round the fragment coordinates down for bounding box
calculations. This also renders the pixel center offset useless, as 0.5
vs ~0.5833333 makes no difference when rounding down.
The SDK seems to write "default" bounding box values before every draw
(1023 0 1023 0 are the only values encountered so far, which happen to
be the extents allowed by the BP registers) to reset the registers for
comparison in the pixel engine, and presumably to detect whether GX has
updated the registers with real values. Handling these writes and
returning them on read when bounding box emulation is disabled or
unsupported, even without computing real values from rendering, seems
to prevent games from corrupting memory or crashing.
This obviously does not fix any effects that rely on bounding box
emulation, but having the game not clobber its own code/data or just
outright crash is a definite improvement.
This fixes a nasty issue where you can change the Dual Core setting
during emulation, if it has been overridden by GameINI or NetPlay, by
simply changing any of the non-disabled settings. This is because
changing any of the settings will write all of them to the config.
This issue is particularly nasty because managing to disable Dual Core
during emulation, and then stopping it, results in the emulator core
being totally deadlocked. It's impossible to recover from this state,
and Dolphin will remain as a zombie process on the system, consuming
resources and holding locks, until forcibly killed.
The GC/Wii GPU rasterizes in 2x2 pixel groups, so bounding box values
will be rounded to the extents of these groups, rather than the exact
pixel. To account for this, we'll round the top/left down to even and
the bottom/right up to odd. I have verified that the values resulting
from this change exactly match a real Wii.
canonicalPath is orders of magnitude slower as it has to perform actual
disk I/O to resolve symlinks, which makes sorting by this column
ridiculously slow for large game lists, especially if the games are on
a NAS. We probably don't need that, simply resolving relative paths
should be sufficient.
std::result_of is deprecated in C++17, and removed in C++20. Microsoft
has gone ahead with the removal as of Visual Studio 16.6.0, so before
this change our code is broken there.
The include for X11Utils.h (and by extension Xlib.h) is gated behind
HAVE_XRANDR, as well as the declaration for this function, but its
definition was mistakenly gated behind HAVE_X11. Therefore, if we have
X11 but not Xrandr, the build will fail due to declaration/definition
mismatch and the missing Window type.
Minizip 1.x is the old broken version, while 2.x is the newer fork we
use. Many distros ship the old version which is causing stack smashing
in RedumpVerifier, so we'll only use the shared lib if it's the newer
version.
The threads can't actually be started when determinism is enabled, as
the behavior would not be deterministic, but Open() still tries to
start the threads and wait, resulting in a deadlock when booting
certain games and homebrew in NetPlay.
For some reason every button group was shoved into the same config
group called "Keys" which caused buggy behavior once someone tried to
have hotkeys with the same name in different groups. This fixes that,
and converts existing configs to the new group names so they don't get
reset.
This fixes Old AX Wii games having no audio when compiled under VS2019.
This also includes some minor code cleanup and moving a function to
avoid duplication.
With the SI poll line count fixed, pretty much all games are polling
twice per frame anyways, making this option superfluous. Since it's a
bit of a gross hack and makes DTMs incompatible with console, let's
just bin it.
This fixes the problem where OBS game capture only grabs the region
inside an ImGui window whenever one is open, when using the OpenGL
backend. Shouldn't have any negative effects, as the scissor would've
been something completely arbitrary anyways.
This may affect other capture software that uses the same hooking
method, but I've only tested OBS.
This fixes the desync on playback of start-from-boot input recordings
made while using the GC adapter, as well as other desyncs that could
potentially occur in other circumstances where this bit is used.
I used a previously reserved bit in the ControllerState to store the
new data, so this shouldn't significantly break backwards
compatibility. However, tools that aren't aware of this new bit may set
it to 0, which will break input recordings that contain it.
This changes the Host Input Authority and Golf Mode checkboxes into a
set of radio buttons, consisting of Fair Input Delay, Host Input
Authority, and Golf Mode. This represents the 3 network modes we have.
Although Golf Mode is just an extension of Host Input Authority, it's
more logical to the user to present it as a separate option, rather
than enabling the Golf Mode checkbox only when Host Input Authority is
enabled. This also eliminates the need to first enable Host Input
Authority before Golf Mode can be enabled.
This also adds tooltips to provide brief descriptions of the options,
as well as reintroducing tooltips that were previously removed.
MemoryWatcher only works on Linux and affects emulation determinism due
to scheduling additional events, which causes NetPlay to desync.
Considering that this interface is a rather specialized use case, the
communication with it is kinda crappy *and* it's affecting emulation, I
think it's best to just axe it and come up with a better implementation
of the functionality.
The logic didn't account for the case where a player leaves, so the
host would be left in a dangling state where the UI is disabled but the
game won't start, requiring a full restart of Dolphin to fix.
We can't join a detached thread, so NetPlayIndex gets deleted before
the notification thread exits, creating a race condition. We switch to
using Common::Event because just sleeping leaves the UI hung on the
thread join for a few seconds.
This is an extension of host input authority that allows switching the
host (who has zero latency) on the fly, at the further expense of
everyone else's latency. This is useful for turn-based games where the
latency of players not on their turn doesn't matter.
To become the so-called golfer, the player simply presses a hotkey.
When the host is the golfer, latency is identical to normal host input
authority.
