Spectator Mode is a new mode added by rc_client that allows for achievement and leaderboard functionality, but does not submit this data to the site, partially allowing for offline achievements. It effectively replaces the former settings for disabling achievements, leaderboards, and RP, which are now always active internally as long as the client is active.
The client can take care of itself and handle its own hardcore status when it toggles, so I can tell the settings widget to contact the manager directly to set it.
Also, gradually reorganizing the settings dialog over the next handful of commits.
The client can handle media changes natively so disabling can take place internally. This code uses the same external calls to load data, but will call either BeginLoad or BeginChangeMedia based on whether any media is already loaded.
Due to the client's handling of media changes (it simply disables hardcore if an unknown media is detected) the existing functionality for "disabling" the achievements is no longer necessary and can be deleted.
Two portions of this need updating.
Anything related to points and unlock counts and scoring uses game_summary now instead of the TallyScore method. Unfortunately this comes with the drawback that I cannot easily at this time access the number of points/unlocks from the other hardcore mode, so things like the second progress bar have been deleted.
Rich presence, which no longer needs to be stored, but can be calculated at request. As the AchievementHeader can now update just the Rich Presence, DoFrame can now simply call a header update with .rp=true and the current Rich Presence will be calculated immediately.
As the two items above are the last remaining things to use a number of the components in AchievementManager, this also deletes: Request V1 (V2 is renamed accordingly), ResponseType, PointSpread, TallyScore, UnlockStatus, and the RP generation and ping methods.
UpdateData in AchievementsWindow now only updates the components being requested, massively improving the window's performance. The parameter is UpdatedItems in AchievementManager, which tracks which portions of the system have been updated for every update callback.
Similarly to the Progress widget (though without the separate object for each box, because each Leaderboard unit is just three text fields stacked vertically), AchievementLeaderboardWidget.UpdateData will now accept three options: destroy all and rebuild, update all, or update a set of rows.
As part of this, AchievementManager::GetLeaderboardsInfo has been refactored to GetLeaderboardInfo to return a single leaderboard for the ID passed in.
AchievementProgressWidget maintains in memory a map of AchievementBox pointers so that UpdateData can operate on them individually. UpdateData is overhauled for three options: UpdateData(true) will destroy the entire list and re-create it from scratch as before, to be used if the game or player changes/closes/logs out. UpdateData(false) will loop through the map and call UpdateData on every achievement box, to be used for certain settings changes such as enabling badges or disabling hardcore mode. UpdateData(set<IDs>) will call UpdateData on only the IDs in the set, to be used when achievements are unlocked.
AchievementBox is an extension of QGroupBox that contains the data for a single achievement, initialized with the achievement data and able to reference AchievementManager to update itself.
While state loading is not allowed in the hardcore mode that most players will use, it is allowed in softcore mode; more importantly, if something fails to unlock or unlocks when it shouldn't in either mode the player can create a save that retains the current achievement state.
This is not a 1 to 1 relationship with how the events look primarily because currently achievement
progress messages are in OnScreenDisplay, which currently vanishes messages automatically.
As this covers the last remaining runtime-based event from the old event handler, that handler has been deleted and the new event handler has been renamed to take its place.
Up to four leaderboards are displayed in a window in the bottom right of the screen (vertically above challenge icons, if there are any). As per RetroAchievements standards, the markers only display the current leaderboard values with no further context necessary.
The active leaderboard data (leaderboards currently being attempted, which get displayed on screen) is now tracked. When a leaderboard is started its value is added to a vector (sorted by start frame). There are a separate set of client events specifically to handle leaderboard trackers, that are used to populate and manage this vector. The top portion of this vector (by RetroAchievement standards, the first four items) is exposed to be displayed on screen.
Also deletes the old runtime-based Achievement Triggered event from the old handler, and the methods used by it to publish to the server and reactivate/deactivate achievements in the runtime.
This change was primarily made to refactor the badge fetching to use the client instead of the runtime, but in the process I also refactored the code to cut down on complexity and duplication. Now the FetchBadge method is passed a function that generates the badge name; this is used to ensure that once the badge is loaded that it is still the desired badge to avoid race conditions.
HashGame has become LoadGame, similar structure with the file loaders but using the client instead. LoadGameCallback has been created to handle the results. The old LoadGameSync has been deleted as have
several hash and load methods that it called.
Deletes AchievementManager::Login, renames LoginAsync to Login, and replaces the one synchronous call in the AchievementSettingsWidget with the async call. There is a minor usability regression in that the UI currently does not notify the user when a login has failed; this will be addressed in a later change (possibly in a different PR).
On Windows 11, when playing windowed in a separate window/widget from the main emulator window, we don't want the window to have rounded corners, as it prevents the corner pixels from being visible
Also make the `Decrypt` method private.
As far as I can tell, the only motivation for exposing the `SetBytes`
and `Reset` methods is to allow `CBoot::SetupWiiMemory` to use the same
`SettingsHandler` instance to read settings data and then write it back.
It seems cleaner to just use two separate instances, and require a given
`SettingsHandler` instance to be used for either writing data to a
buffer or reading data from a buffer, but not both.
A natural next step is to split the `SettingsHandler` class into two
classes, one for writing data and one for reading data. I've deferred
that change for a future PR.
This is a JitArm64 version of 219610d8a0.
Due to limitations on how far you can jump with a single AArch64 branch
instruction, going above the former limit of 128 MiB of code (counting
nearcode and farcode combined) requires a bit of restructuring. With the
restructuring in place, the limit now is 256 MiB. See the new large
comment in Jit.h for a description of the new memory layout.
To ensure memory safety, callers of GetPointer have to perform a bounds
check. But how is this bounds check supposed to be performed?
GetPointerForRange contained one implementation of a bounds check, but
it was cumbersome, and it also isn't obvious why it's correct.
To make doing the right thing easier, this commit changes GetPointer to
return a span that tells the caller how many bytes it's allowed to
access.
This fourth part of my series of patches to get rid of unsafe uses of
GetPointer takes care of the "easy" cases in VideoCommon. Three uses of
GetPointer now remain in Dolphin: VertexLoaderManager, TextureInfo, and
the software renderer's TextureSampler.
All relevant games other than Pikmin 1 Wii seem to always set the two
dwords to zero, so previously they were ignored during command dispatch
and now we still ignore them but in the right place.
For some reason Linux is surprisingly slow at closing file descriptors
of event devices. This commit improves GUI startup times on my computer
by about 1.5 seconds.
When writing the software FMA code, I didn't realize that we can't
overwrite d if d is the same register as one of the inputs and
HandleNaNs is going to be called. This fixes that.
It was possible for sAlertMessageLock.notify() to be called before
sAlertMessageLock.wait(), causing Dolphin to deadlock. In particular,
this was guaranteed to happen if displayAlertMsg was called from the UI
thread while the emulation activity is being destroyed, because
runOnUiThread runs the passed-in anonymous function immediately when
called from the UI thread.
By replacing Object.wait/Object.notify with Semaphore.acquire/
Semaphore.release, it no longer matters what order the methods are
called in.
Because SettingViewHolder is used in RecyclerViews, we have to
explicitly unset STRIKE_THRU_TEXT_FLAG when we don't want it, otherwise
it might be left over from when the SettingViewHolder was representing
a different setting.
On all platforms, this would result in out of bounds accesses when getting the component sizes (which uses stuff from VertexLoader_Position.h/VertexLoader_TextCoord.h/VertexLoader_Normal.h). On platforms other than x64 and ARM64, this would also be out of bounds accesses when getting function pointers for the non-JIT vertex loader (in VertexLoader_Position.cpp etc.). Usually both of these would get data from other entries in the same multi-dimensional array, but the last few entries would be truly out of bounds. This does mean that an out of bounds function pointer can be called on platforms that don't have a JIT vertex loader, but it is limited to invalid component formats with values 5/6/7 due to the size of the bitfield the formats come from, so it seems unlikely that this could be exploited in practice.
This issue affects a few games; Def Jam: Fight for New York (https://bugs.dolphin-emu.org/issues/12719) and Fifa Street are known to be affected.
I have not done any hardware testing for this PR specifically, though I *think* I previously determined that at least a value of 5 behaves the same as float (4). That's what I implemented in any case. I did previously determine that both Def Jam: Fight for New York and Fifa Street use an invalid normal format, but don't actually have lighting enabled when that normal vector is used, so it doesn't change rendering in practice.
The color component format also has two invalid values, but VertexLoader_Color.h/.cpp do check for those invalid ones and return a default value instead of doing an out of bounds access.
IOS::HLE::IOCtlVRequest::Dump sometimes tries to call GetPointerForRange
with an address of 0 and a size of 0. Address 0 is valid, but we were
mistakenly also trying to check that address 3FFFFFFF is valid, which it
isn't.

Move CheatManager's child widgets into scroll areas to allow making the
window smaller than the default.
In CheatSearchWidget, enable word wrapping for the label describing the
address space and search type to help it fit better inside a narrower
window.
Typically when someone uses GetPointer, it's because they want to read
from a range of memory. GetPointer is unsafe to use for this. While it
does check that the passed-in address is valid, it doesn't know the size
of the range that will be accessed, so it can't check that the end
address is valid. The safer alternative GetPointerForRange should be
used instead.
Note that there is still the problem of many callers not checking for
nullptr.
This is part 2 of a series of changes removing the use of GetPointer
throughout the code base. After this, VideoCommon is the one major part
of Dolphin that remains.

This is the first part of a series of changes that will remove the usage
of GetPointer in different parts of the code base. This commit gets rid
of every GetPointer call from our IOS code except for a particularly
tricky one in BluetoothEmuDevice.
RCOpArg::ExtractWithByteOffset is only used in one place: a special case
of rlwinmx. ExtractWithByteOffset first stores the value of the
specified register into m_ppc_state (unless it's already there), and
then returns an offset into m_ppc_state. Our use of this function has
two undesirable properties (except in the trivial case `offset == 0`):
1. ExtractWithByteOffset calls StoreFromRegister without going through
any of the usual functions. This violated an assumption I made when
working on my constant propagation PR and led to a hard-to-find bug.
2. If the specified register is in a host register and is dirty,
ExtractWithByteOffset will store its value to m_ppc_state even when
it's unnecessary. In particular, this always happens when rlwinmx
uses the same register as input and output, since rlwinmx always
allocates a host register for the output and marks it as dirty.
Since ExtractWithByteOffset is only used in one place, I figure we might
as well inline it there. This commit does that, and also alters
rlwinmx's logic so the special case code is only triggered when the
input is already in m_ppc_state.
Input in `m_ppc_state`, before (11 bytes):
mov esi, dword ptr [rbp-104]
mov dword ptr [rbp-104], esi
movzx esi, byte ptr [rbp-101]
Input in `m_ppc_state`, after (5 bytes):
movzx esi, byte ptr [rbp-101]
Input in host register, before (8 bytes):
mov dword ptr [rbp-104], esi
movzx esi, byte ptr [rbp-101]
Input in host register, after (3 bytes):
shr edi, 0x18
There were three distinct mechanisms for signaling symbol changes in DolphinQt: `Host::NotifyMapLoaded`, `MenuBar::NotifySymbolsUpdated`, and `CodeViewWidget::SymbolsChanged`. The behavior of these signals has been consolidated into the new `Host::PPCSymbolsUpdated` signal, which can be emitted from anywhere in DolphinQt to properly update symbols everywhere in DolphinQt.
This PR simply exposes the tapserver options in Serial Port 1 on Android. They already exist and work, but are not selectable. I've tested the tapserver options myself with Phantasy Star Online Episode I & II and they work fine.
Not sure if the behavior I'm implementing here is what real hardware
does, but since this is a buffer overflow, I'd like to get it fixed
quickly. Hardware verification can happen later.

Having to look up macros that are defined elsewhere makes the code
harder to reason about. The macros don't remove enough repetition to
justify their existence in my opinion.
With this, I intend to make it clearer that Auto, Force 4:3, Force 16:9
and Custom are really the same thing, just with the aspect ratio of the
simulated TV being selected in a different way. I also extended the
introduction in a way I feel will clarify things but which you are
welcome to bikeshed :)
I was thinking of this during the review of 41b19e262f, but wanted to
put it in a separate PR as to avoid blocking it on bikeshedding.
I'm a bit unsure what to do about the word "analog" in "analog TV". I
felt that repeating it for each of these options would be too
repetitive. I suppose there's a reason why we used the word originally,
but digital TVs do give you basically the same aspect ratio for GC/Wii
games as analog TVs. (Of course, whether it's 4:3-like or 16:9-like
depends on what aspect ratio you set in the TV's settings, but that's
the case for widescreen CRTs too.)
When the divisor is a constant value, we can emit more efficient code.
For powers of two, we can use bit shifts. For other values, we can
instead use a multiplication by magic constant method.
- Example 1 - Division by 16 (power of two)
Before:
mov w24, #0x10 ; =16
udiv w27, w25, w24
After:
lsr w27, w25, #4
- Example 2 - Division by 10 (fast)
Before:
mov w25, #0xa ; =10
udiv w27, w26, w25
After:
mov w27, #0xcccd ; =52429
movk w27, #0xcccc, lsl #16
umull x27, w26, w27
lsr x27, x27, #35
- Example 3 - Division by 127 (slow)
Before:
mov w26, #0x7f ; =127
udiv w27, w27, w26
After:
mov w26, #0x408 ; =1032
movk w26, #0x8102, lsl #16
umaddl x27, w27, w26, x26
lsr x27, x27, #38
