Adding a community-requested list of Gecko and Action Replay codes to the allowlist. Many of these codes were from the wiki and are being added to Dolphin's repo for the first time.
Change the displayed controls in the TAS Input window when the
controller's extension (including MotionPlus) is changed.
This previously required restarting Dolphin after the attachment was
changed, as the controls were never updated after the WiiTASInputWindow
was created at Dolphin startup.
When I wrote 71e9766519, there was an interaction I didn't take into
account: When setting eq, SetCRFieldBit assumes that all bits in the
passed-in host register except the least significant bit are 0. But if
we use EON or ORN, all bits except the least significant bit get set to
1. This can cause eq to end up unset when it should be set.
This commit fixes the issue.
crandc is unaffected by the issue because the "1" bits get ANDed with
"0" bits from the first operand.
Note that in practice, we never have both bits_1_to_31_are_set and
negate at once, so while it looks like this commit adds an extra AND
instruction in some cases, those cases don't happen in practice, meaning
this fix shouldn't affect performance.
QCheckBox::toggled and other similar signals are used to save changes and to update widget status (such as enabled).. OnConfigChanged needs to load new values and trigger widget updates, but the new value shouldn't trigger a save. A save is unnecessary (the config has the correct values and the UI is being updated to those values) and it'd trigger another ConfigChanged signal. This commit blocks the save without blocking the signal entirely.
The computed value is only used when the register is equal to zero, so
we can fully precompute it and materialize the constant instead. In
other words, we change from
```
return reg == 0 ? (reg | 1ULL << 63) : reg;
```
to
```
return reg == 0 ? 1ULL << 63 : reg;
```
The number of instructions remains the same, but we eliminate an
unnecessary dependency on the register value.

In NandPaths.cpp, the `std::initializer_list<char>` of illegal characters has been turned into a `char[]` (similar to the one in GameList.cpp).
The reverse iteration in ResourcePack.cpp seemed to provide no benefits, and doing without it it seemed to have no ill effects.
The new `Common::Contains` and `Common::ContainsSubrange` function objects mirror C++23's `std::ranges::contains` and `std::ranges::contains_subrange`, respectively.
Recently there was some issues in TASVideos trying to sync a Donkey Kong Country Returns TAS. It eventually was synced by directly using the config from the TAS author. The exact setting which caused the desync was narrowed down to being in SYSCONF, with the country code. The TAS author lives in the US, so the country code matched the US country code, while the person attempting to sync the TAS did not live in the US.
Adding SYSCONF country code to the DTM should avoid this being an issue for future Dolphin versions.
When the input register and carry flags are known, we can always
precompute the result.
We still materialize the immediate when the condition register
needs to be updated, but this seems to be a general problem. I might
look into that one day, but for now this'll do.

Resolves duplicate OSD messages for Loading and Found custom textures.
VideoBackend initialization results in HiresTexture::Init being called.
We already call HiresTexture::Update when OnNewTitleLoad is called.
Thus we can remove HiresTextures::Init completely as it is redundant.
No games seem to use this, so this isn't useful as a performance
optimization, but it's required for correctness because the (sh == 0)
case of our implementation doesn't handle zero masks.
In JitRegCache.cpp, the lambda predicate were replaced by a pointer to member function because ranges algorithms are able to invoke those.
In ConvertDialog.cpp, the `std::mem_fn` helper was removed because ranges algorithms are able to handle pointers to member functions as predicates.
In BoundingBox.cpp, the lambda predicate was returning the bool element unchanged, so `std::identity` was a better fit.
In WiimoteReal.cpp, JitRegCache.cpp, lambda predicates were replaced by pointers to member functions because ranges algorithms are able invoke those.
In ConvertDialog.cpp, the `std::mem_fn` helper was removed because ranges algorithms are able to handle pointers to member functions as predicates.
In DITSpecification.cpp, MaterialAsset.cpp, and ShaderAsset.cpp, lambda predicates were replaced by pointers to member functions because ranges algorithms are able invoke those.
In NetPlayClient.cpp, the non-trivial `NetPlay::Player` elements were being passed by value in `NetPlayClient::DoAllPlayersHaveGame()`. This has been fixed.
In WIABlob.cpp, the second example's predicate was returning the `std::optional` by value instead of implicitly converting it to a bool. This has been fixed.
Creates a layer outside the game config layer system and passes it to the created gfx widows, so as to not interfere with the global config system.

New code adds a test failure if there's a Patches/Gecko/AR_Retroachievements_Verified code that doesn't appear to actually exist in the file. This will catch if the allowed patch is formatted wrong, which I found happening several times already due to not realizing that the patch author's name would need to be omitted.
Prefer BLENDVPD over VBLENDVPD if the latter doesn't save any
instructions.
VBLENDVPD allows separate source and destination registers, which can
eliminate a MOVAPD/MOVSD. However, on Intel since Skylake, VBLENDVPD
takes additional uops to execute compared to BLENDVPD (according to
https://uops.info). On AMD and older Intel microarchitectures there is no
difference.
Some generators (like Unix Makefiles and Xcode) copy an app's Info.plist at configure time.
This causes a problem when we need to generate the Info.plist at build time, like how we
currently do it with ScmRevGen. Instead of generating the Info.plist directly in ScmRevGen,
provide an Info.plist without any version information to CMake at configure time, have
ScmRevGen generate a separate plist file with the version information at build time, and
then merge the two together to create the final Info.plist.
The read thread could call Reset, which in turn tried to join the read
thread, leading to a SIGABRT. This manifested as Dolphin consistently
crashing when disconnecting a GC adapter and having a chance of crashing
a few seconds after connecting a GC adapter.
Now that patches and codes are enabled on a case by case basis, remove patcher code blocking codes entirely in hardcore mode, and reword the warning to be more accurate.
This apparently didn't compile on macOS six years ago before c++20, but
it should be fine by now.
While I'm at it, make the constants upper case per convention.
If the host is in hardcore mode, all joining players will be set to hardcore mode; if not, all joining players will be set to softcore. This ensures all players have the same settings and remain synchroized.
The primary focus of this PR is the Eternal Darkness patch which fixes hanging at startup, which prior to this fix makes Eternal Darkness unplayable in hardcore. The MHTri patch was added as well simply because it could be.
GXAbortFrame() is problematic for Dolphin because it first writes
PI_FIFO_RESET (for which we discard our internal fifo), then disables CP
reads (for which we execute pending commands in the GP fifo in emulated
memory). I don't know whether there is a race condition on hardware, but
there is one for us. Avoid this by also doing a GPU sync here.
The value being stored must be loaded into a register. In the case of an
immediate value, this means it must be materialized. The value is
eventually byteswapped before performing the store.
This can be simplified for the value 0 for two reasons:
- ARM64 has a dedicated zero register, so does not need to be
materialized.
- Byteswapping zero is still zero, so we can skip this step.
We could skip byteswapping for other values by immediately materializing
the byteswapped value in a register, but the benefits are not so clear
there (if the value needs to be materialized anyway, it is better to do
it up front).

Unlike on x64, inverting EQ or GT in SetCRFieldBit saves us one
instruction. Also unlike on x64, inverting SO or LT in GetCRFieldBit
requires an extra instruction (just like in SetCRFieldBit). Due to this,
replacing an invert in GetCRFieldBit with an invert in SetCRFieldBit
when possible is either equally good or better - never worse.

Makes Graphics -> Hacks -> Skip EFB Access from CPU enabled by default. Some GPU drivers stall when EFB access occurs in games where EFB is not used. Most games that require this setting set to 'true' already have this defined in their game inis.
`std::erase` is a replacement for the remove-erase idiom.
Changes to `OpenModeToAndroid` inadvertently revealed that the prior implementation had UB (potentially deleting the end iterator). This is now fixed.
Three bugs specific to older Wii games:
- The size difference between high-pass and biquad filter was not
accounted for, causing wiimote related fields to be corrupted.
- Wiimote sample buffer pointers were advanced by 32 samples per
millisecond instead of 6 samples. Usually hidden by the first bug.
- PB updates on Wii were being byte-swapped twice, but I've not actually
found any Wii games that make use of PB updates.
This fixes wiimote audio in at least the following games:
- Excite Truck
- Ice Age 2: The Meltdown
- Kororinpa: Marble Mania
- Rapala Tournament Fishing
- Shrek the Third
- Super Monkey Ball: Banana Blitz
- Tiger Woods PGA Tour 07
- WarioWare: Smooth Moves (issue 11725)
- Wing Island
Recently we have been getting some requests to make the existing vsync
setting available in the Android GUI:
https://bugs.dolphin-emu.org/issues/13650https://forums.dolphin-emu.org/Thread-vsync-toggle-for-android
I don't quite understand why enabling the vsync setting is helpful when
Android already enforces vsync, but I guess having the option available
doesn't hurt. I'm putting the setting under Advanced, unlike in
DolphinQt, since there's no clear reason why the typical user would want
to use this setting.
Fixes LIT (https://bugs.dolphin-emu.org/issues/13635). The text does not include normals, but has lighting enabled. With the previous default of (0, 0, 0), lighting was always black (as dot(X, (0, 0, 0)) is always 0). It seems like the normal from the map in the background (0, 0, 1) is re-used.
LIT also has the vertex color enabled while vertex color is not specified, the same as SMS's debug cubes; the default MissingColorValue GameINI value of solid white seems to work correctly in this case.
No need to materialize the immediate if it is zero, we can just use WZR.

In VolumeVerifier.cpp, constructing a `std::string_view` of the volume's GameID is unnecessary, as `std::`(`ranges::`)`binary_search` supports heterogeneous lookup. The usage in GameFile.cpp is a perfect example.
In OGLConfig.cpp, `std::views::reverse` is used rather than sorting using `std::ranges::greater` in order to parallel other instances of reverse iteration in the function.
In DSPCore.cpp, there were two `std::fill` uses that could be simplified using `std::fill_n`. Due to their proximity with other `std::fill` algorithms being modernized with ranges, I chose to make these examples into the rare `std::ranges::fill_n`.
In StringUtil.h, the lambdas wrapping `Common::ToLower(char)` and `Common::ToUpper(char)` were only necessary due to the function names being overloaded.
Many games call GXSetGPFifo() without first waiting for the GP to finish
consuming outstanding commands in the previous GP fifo. Normally,
Dolphin runs OpcodeDecoding in 1000-cycle time slices. In that time
frame, GXSetGPFifo() has probably completed and the GP read pointer now
points to entirely new memory. If the last GP fifo copy ended in an
incomplete command, the new GP fifo would most likely desync for a
while. To avoid all this, give the GP a time slice right now to copy the
remaining data from the previous GP fifo.
Indexed XF loads specify the number of 32-bit words (generally floats, but light data has some integers) to load, not the number of bytes. This was only a mistake in the fifo analyzer text; the actual implementation already loaded words.
The light LIT fifolog from https://bugs.dolphin-emu.org/issues/13635 has position data at physical address 11ae3180. This works fine when using the memory viewer in physical mode, but the corresponding virtual address (91ae3180) previously didn't show anything in effective mode. It works fine now though.
This shouldn't affect playback of fifologs as everything in there uses physical addresses; this only impacts the memory viewer.
This logic was copied from CBoot::SetupBAT.
This reverts the revert commit bc67fc97c3,
except for the changes in BaseConfigLoader.cpp, which caused the bug
that made us revert 72cf2bdb87. PR 12917
contains an improved change to BaseConfigLoader.cpp, which can be merged
(or rejected) independently.
A few changes have also been made based on review comments.
Found this bug while testing; if I manually edit the config files while Dolphin is closed I was able to get debug and hardcore on at the same time, this resolves that.
AchievementManager::SetHardcoreMode now handles the (non-Qt) settings disabled by hardcore mode, instead of doing this on the Qt layer. Also ensured Init/Enable Achievements paths run this code, fixing the bug wherein the player can manipulate things when achievements are disabled that persist when turned back on.
Dolphin has been using edge-to-edge rendering for a little while now,
but it has required a bit of manual work. Now that edge-to-edge is
becoming something expected of apps in Android 15, there's a nicer API
we can use.
Tested on Android 8, 11 and 13, with no changes in behavior noted.
So far, Dolphin hasn't been able to run on Android devices that use a
16 KiB page size. 16 KiB page sizes are a very new Android feature that
no phones have shipped with so far, so we're still compatible with the
phones that exist out there, but let's get this fixed before phones
start shipping with 16 KiB page sizes.
Because I couldn't get Android Studio's emulator to work, I haven't been
able to confirm that this change actually makes Dolphin fully compatible
with devices that use a 16 KiB page size. But I have confirmed that this
doesn't break anything on a regular 4 KiB page size device.
Prevent potential issues when creating the Graphics window (and thus
calling PopulateBackendInfo) while the core state is Stopping, like we
already do while it's Starting or Running.
Remove the PopulateBackendInfoFromUI function, which had a single caller
(GraphicsWindow::OnBackendChanged) and checked that the core wasn't
running or starting before calling PopulateBackendInfo.
Move the core state check into PopulateBackendInfo and have
OnBackendChanged call that instead. This guarantees the check is
performed by all callers of PopulateBackendInfo, preventing
potential reintroduction of the crash fixed in 3d4ae63f if another call
to PopulateBackendInfo is added.
As of the previous commit the only other caller of PopulateBackendInfo
is Core::Init shortly before s_state is set to Starting, so it will
always pass the check and so maintain its current behavior.
Remove the second of two calls to PopulateBackendInfo during emulation
startup. This call was originally the only one, but b214e0e added an
earlier call to handle the backend being changed by the GameINI.
The PR discussion doesn't explain why the original call was left in; I
suspect it was just overlooked.
As a bonus, this removes one of the extra copies of the "Video Info" On
Screen Display message at startup when using OpenGL.
Fix a crash when opening the Graphics window for the first time during
emulation startup when the backend is Vulkan, D3D11, or D3D12.
Don't call PopulateBackendInfo() from the Host thread when the core is
starting up. First, the function has already been called in Core::Init()
so we don't need to again. More importantly, PopulateBackendInfo() calls
g_video_backend->InitBackendInfo(), and the Vulkan and D3D
implementations of those functions load and then unload libraries (and
their associated function pointers) which are potentially in use by
other threads.
This crash was reliably reproducible with the following steps:
1) Select an affected backend.
2) Enable "Compile Shaders Before Starting"
3) Delete the cached shaders (but not the .uidcache file) for the game
you're testing.
4) Close and reopen Dolphin.
5) Start the game.
6) While the game is still booting or compiling shaders, open the
Graphics window for the first time in that Dolphin session.
Fixes https://bugs.dolphin-emu.org/issues/13634.
Before, Dolphin would randomly crash when updating the cheat search when automatic refresh was enabled. (Having a large number of addresses listed, e.g. by starting with an "any value" search, may contribute). The crash was due to QTableWidget::item returning nullptr in RefreshGUICurrentValues, presumably due to the table being resized on the UI thread while the emulated CPU thread was updating the values. I've fixed this by pausing the CPU thread for the entirety of OnNextScanClicked; this eliminated crashes in my testing.
With 12 uses of `JoinStrings` in the codebase vs 36 uses of `fmt::join`, fmtlib's range adapter for string concatenation with delimiters is clearly the preferred option.
Migrating `Common::CaseInsensitiveLess` to StringUtil.h will hopefully discourage rolling one's own solution in the future for case-insensitive associative containers when this (quite robust!) solution already exists.
`Common::CaseInsensitiveStringCompare::IsEqual` was removed in favor of using the `Common::CaseInsensitiveEquals` function.
The `a.size() != b.size()` condition in `Common::CaseInsensitiveEquals` can be removed, since `std::ranges::equal` already checks this condition (confirmed in libc++).
