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.

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
This implements the GameCube modem adapter. This implementation is stable but not perfect; it drops frames if the receive FIFO length is exceeded. This is probably due to the unimplemented interrupt mentioned in the comments. If the tapserver end of the connection is aware of this limitation, it's easily circumvented by lowering the MTU of the link, but ideally this wouldn't be necessary.
This has been tested with a couple of different versions of Phantasy Star Online, including Episodes 1 & 2 Trial Edition. The Trial Edition is the only version of the game that supports the Modem Adapter and not the Broadband Adapter, which is what made this commit necessary in the first place.
This expands the tapserver BBA interface to be available on all platforms. tapserver itself is still macOS-only, but newserv (the PSO server) is not, and it can directly accept local and remote tapserver connections as well. This makes the tapserver interface potentially useful on all platforms.
Testing found that spamming toggles for Enable Leaderboards etc risked leaderboards being deleted while the runtime was in the process of recalculating them; this should clear up those conflicts.
Cubeb logs a message at CUBEB_LOG_NORMAL verbosity every time you start
or stop a stream which can get a bit annoying when using frame advance
at Dolphin's default verbosity.
Window icon was missing from QDialog lacking a parent.
Giving the QDialog a parent revealed I had failed to make it properly non-modal, necessitating further changes.
Settings save less often, now only upon destruction.
Construction of BranchWatchDialog is now deferred.
Not only was the extra call to the update callback in the AchievementEventHandler method unnecessary, it was getting called on events that don't even need to be tracked here, causing a lot of lag when it turned out one achievement was repeatedly spamming Achievement Reset Events as a shortcut.
Failing to do this was causing challenge icons to carry over into the next game if a game was closed while the icons were active, even if the next game to run was a completely different game entirely with completely different badges.
RetroAchievements plans to use the user_agent in unlock requests to determine which software version was used to play the game, and can filter older software versions out. As such, I have been given the go-ahead to remove the hardcoded line that forces hardcore to always be false.
This takes care of making the image clearer in some edge cases where the game was already running at near perfect
4:3 with no stretching, and the VI aspect ratio didn't match the XFB by one pixel, making the image stretched and blurry.
-Video: Fix `FindClosestIntegerResolution() using the window aspect ratio and not the draw aspect ratio, causing it to prefer
stretching over black bars in cases when it wasn't desirable.
Two minor updates to improve the Achievement Manager's handling of a player's completion rate.
One, UnlockStatus and the unlock map now track achievement category, such that TallyScore does not count unofficial achievements in counts/points.
Two, the determinations for mastery/completion are now improved to check (1) that the achievement triggering this is CORE (not UNOFFICIAL) and (2) that it has not already been unlocked at this level on the site, which should be sufficient to determine that the unlocking of this particular achievement completes/masters the game.
* Fix irregularly shaped corners
* Remove extra space for BalloonTips with no message or no title
* When the target tip location is not on a screen, put the tooltip on
the mouse's screen instead of the primary screen
* Fix description getting cut off when the title was too long
* Expose border width as a parameter
* Fix spacing and sizing issues with larger border widths
Most obviously, there is no longer a warning message to the player in the achievement window that achievements are disabled if a game is not currently running.
Use "bzip2" instead of "bzip" in optparse's compression choices for the
convert command. This is both more accurate and matches what the
ParseCompressionTypeString function expects.
The mismatch between the two parsing functions prevented compression
using bzip2 because either ParseCompressionTypeString or optparse would
generate an error when using "bzip" or "bzip2" respectively.

This fixes an issue introduced by 3b0444be6b
where the m_accelerator would not be initialized when loading a savestate if
the current UCode mismatched the UCode in the savestate, leading to a crash.
When performing a default compilation with recent GCC & glibc,
the use of -Werror=nonnull causes a build error.
The error is given as IOFile::ClearError() can call std::clearerr()
with a null file, which can trigger a null-pointer dereference in libc.
Change the std::clearerr() call to be conditional on a file being open.
Google Play's policies require us to tell the user the size of any large
download.
The size seems to vary by just a megabyte or two across regions in my
testing, so I'm listing a rough size for all the regions.
I'm also taking the opportunity to shorten the message to make it easier
to read.
Because the wording of the Load Wii System Menu string can change
depending on the contents of the NAND, we should update that menu item in
a method that's guaranteed to get called every time the user opens the
menu rather than one that's only guaranteed to be called once.
Unlike ADD (immediate), MOV (register) treats SP as ZR. Therefore the
ADDI2R optimization that was added in 67791d227c can't optimize ADD to
MOV when exactly one of the registers is SP.
There currently isn't any code in Dolphin that calls ADDI2R with
parameters that would trigger this case.
Adds a setting field under the hood to retain which folder the player last saved/loaded a state to/from, so that the dialog box to select a state to save/load reopens at that folder.
Because the last commit made us use separate folders for GCPad and
GCKey profiles, we should also use separate game INI keys for them.
Otherwise setting e.g. PadProfile1 in a game INI will make both GCPad
and GCKey try to load it, typically with one of them succeeding and the
other one showing a panic alert due to the profile not existing in its
folder.
Better do this breaking change for GCKeys in the same PR as the other
breaking change rather than later.
After reading the previous commit, you might think "hold on, what's the
difference between GetProfileName and GetProfileDirectoryName"? These
two are being used for the exact same thing - figuring out where
profiles are stored - yet they return different values for certain
controllers like GC keyboards! As far as I can tell, the existing code
has been broken for GC keyboards since they were introduced a decade
ago. The GUI (and more recently, also InputCycler) would write and read
profiles in one location, and our code for loading profiles specified in
a game INI file would read profiles in another location.
This commit gets rid of the set of values used by the game INI code in
favor of the other set. This does breaking existing setups where a
GCKey profile has been configured in a game INI, but I think the number
of working such setups is vanishingly small. The alternative would make
existing GCKey profiles go missing from the profile dropdown in the GUI,
which I think would be more disruptive. The alternative would also force
new GCKey profiles into the same directory as GCPad profiles.
This commit also fixes a regression from d6c0f8e749. The Android GUI was
using GetProfileName to figure out what key to use in the game INI,
which made it use incorrect game INI entries for GameCube controller
profiles but not Wii Remote profiles. Now the Android GUI uses
GetProfileKey for this, fixing the problem.
By having getters for this information, other code that needs access to
the same information can call the getters instead of duplicating the
information.
