USBDevicePicker: Modify USBDeviceAddToWhitelistDialog to be more generic, and use it for a new "More Options..." selection in Bluetooth Passthrough adapters
When opening a file dialog to set the location of a custom path, use the
corresponding user path as the starting location instead of the current
custom path.
When no custom path was set the dialog would be opened with a blank path
which causes Windows (not sure about other platforms) to open the dialog
at the same location where the last dialog was closed, or at the current
working directory if no previous dialog had been opened.
If a nonempty custom path has been set then it has also set the
corresponding user path, so the behavior in that case is unchanged.
Dual Core is primarily known as one of the first troubleshooting steps when emulation or NetPlay misbehave.
I believe(?) the original intent with having it on by default was likely to support users with weaker machines. However, I believe it would be a lot more reasonable for users to manually enable dual core if they really need the performance boost, rather than it is for them to have come ask us in support channel why their cleanly-installed Dolphin is not emulating their games properly.
Instead, this creates a fragile first impression where a clean install of Dolphin is already set up in a way that leads to inexplicable crashes, subtle timing bugs, and NetPlay desyncs.
Note: This changes only applies to the Desktop application, since mobile devices *do* really need the performance boost.
Remove window hints clearing the flag Qt::WindowContextHelpButtonHint,
which is already off by default in Qt 6.
In Qt 5 this flag was set by default for QDialogs, and on Windows put a
? button in the corner of the title bar allowing users to activate Qt's
QWhatsThis help system for a given widget. Since we don't set that text
the ? button was useless and so we hid it manually.
This feature allows overriding the frequency of the Vertical Blank Interrupt. For many games, this means that their gameplay speed will change without affecting audio, which would be useful by itself (e.g. grinding in RPGs).
However, there are games that use delta time for their game logic, which allows them to be played at >60 FPS at the same gameplay speed!
Some games aren't dynamic though, and require a patch to adjust their game speed variable.
Removed VolumeChanged signal, as ConfigChanged will trigger what is needed.
Only applies UpdateSoundStream to things that can change during emulation.
Settings::SetVolume might no longer be used, but left it in.
Introduce a new "Enable Time Tracking" checkbox in the InterfacePane UI. The checkbox is dynamically enabled or disabled based on the emulation state, preventing changes while emulation is active.
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.
