Any call to Config::SetCurrent will cause the relevant setting
to show up as overridden in the Android GUI, which can be confusing,
so let's not do it when the new value is the same as the original.
SYSCONF very much is saveable. Whether it's in IsSettingSaveable
or not hasn't mattered until now since the SYSCONF settings use
separate config loader code that doesn't check IsSettingSaveable,
but the next commit will require SYSCONF to be marked as saveable.
The main activity loads settings essentially as soon as it
starts, in order to determine which tab to show. If the process
of stopping emulation has not finished at this point, a race
condition may be triggered where two IOS kernels are created
at once due to the emulation thread loading or saving the
SYSCONF while the GUI thread is loading the SYSCONF. To fix
this, we can wait for emulation to fully end before returning.
Because this race condition is hard to reproduce, I have not
been able to test that this actually fixes the race condition,
or even that the cause of the race condition is exactly what I
believe it is. But I am relatively confident.
The only place where initTouchPointer was called automatically
was Host_RequestRenderWindowSize, which is called at least once
after emulation start, but not after activity recreation.
I was hoping we would be able to pull in the default values
from C++, but it seems like more trouble than it's worth,
partially because of different settings having default values
of different types and partially because we don't have any
convenient way to get a list of all C++ settings.
Except controller settings, because those would be annoying
to fit into the same system, and I only need the non-controller
settings to be brought over for the next commits to work.
...instead of waiting for it after launching EmulationActivity.
We need this because there is code that runs very early in
EmulationActivity that accesses the settings.
Android TV devices aren't the only devices without touchscreens.
Regarding MotionAlertDialog, I could've replaced the leanback
check with a touchscreen check instead of just removing it,
but I thought there was no reason to prevent people with
touchscreens from doing a long back press if they want to.
https://bugs.dolphin-emu.org/issues/12029
We currently have one way of opening the menu on touch screen
devices (swiping down from the top of the screen to bring up the
action bar and selecting the menu in the action bar), and another
way of opening the menu on Android TV (pressing Back). However,
some devices that claim to support touch (or don't support
leanback? Dolphin currently conflates the two) don't actually let
you swipe down from the top of the screen in the way that Dolphin
expects, notably Chromebooks. There are also some phones where you
can swipe down from the top of the screen but this for some reason
doesn't lead to the action bar becoming visible, though we are
getting less reports about this nowadays than in the past.
This change makes us use the Back method on all devices,
since it should work on all devices with no significant drawbacks.
Unfortunately, we not only have two different ways of triggering
the menu but actually two entirely different menus, with the
non-touch menu not implementing options that only are revelant
when using a touch screen. A later commit will add the missing
features to the menu that we now use on all devices.
The reason why the finish() call was added no longer exists.
(Also, there was never a duplicate SettingsActivity as far as
I can tell, only a duplicate SettingsFragment.)
Fixes https://bugs.dolphin-emu.org/issues/12245.
I considered making a change to DolphinQt instead of
the core, but then additional effort would've been
required to add the same fix to the Android GUI once
we start using the new config system there.
It's possible (but rare) for a WIA or RVZ file to support
this for some partitions but not all, and for the game and
the blob code to disagree on how large a partition is.
In particular, I wanted to do change this in
AudioInterface::Init so that dumped GC audio doesn't need
to have a file split (changing from 32000 Hz to 32029 Hz)
when the emulated software initializes the AI registers.
I've also made the same change to DI's DTK code.
The heuristic was not allocating enough space for Metroid: Other M,
at least when using the default settings. (This didn't break the
file, it just caused some headers to be placed at the end of the
file instead of at the start and wasted a few hundred kilobytes.)
The new hash check catches essentially all desync problems
that VolumeVerifier can catch, so from the user's perspective,
such problems will result in Dolphin refusing to start the
game on netplay rather than actually getting a desync.
When I first made VolumeVerifier, I figured that the distinction
between an unsigned ticket and an unsigned TMD was a technical
detail that users would have no reason to care about. However,
while this might be true for discs, it isn't equally true for
WADs, due to the widespread practice of fakesigning tickets to
set the console ID to 0. This practice does not require
fakesigning the TMD (though apparently people do it anyway,
at least sometimes...), and the presence of a correctly signed
TMD is a useful indicator that the contents have not been
tampered with, even if the ticket isn't correctly signed.
FCVT doesn't necessarily round to zero, so the result
might be inaccurate if we use it. To ensure correct
rounding, we use FCVTS from double FPR to 32-bit GPR.
Unfortunately, FCVTS can't do double FPR to single FPR.
This is now unused. Seems like it was an improper fix
(there would be a race if saving the screenshot took longer
than 2 seconds) back when it was used too.
Just for maintainability. This is a shorter and more standard
solution compared to our current one where the Fragment
persists the Settings and passes it to the Activity.
Other than the controller settings and JIT debug settings,
these are the only settings which were defined in Java code
but not defined in the new config system in C++. (There are
still a lot of settings that are defined in the new config
system but not yet saveable in the new config system, though.)
Instead of comparing the game ID, revision, disc number and name,
we can compare a hash of important parts of the disc including
all the aforementioned data but also additional data such as the
FST. The primary reason why I'm making this change is to let us
catch more desyncs before they happen, but this should also fix
https://bugs.dolphin-emu.org/issues/12115. As a bonus, the UI can
now distinguish the case where a client doesn't have the game at
all from the case where a client has the wrong version of the game.
The CMake Windows build was broken because of me adding a usage
of std::codecvt_utf8_utf16 to StringUtil.cpp. Kinda silly to have
a warning for an API with no standard replacement available...
It is my opinion that nobody should use NKit disc images without
being aware of the drawbacks of them. Since it seems like almost
nobody who is using NKit disc images knows what NKit is (hmm, now
how could that have happened...?), I am adding a warning to Dolphin
so that you can't run NKit disc images without finding out about the
drawbacks. In case someone really does want to use NKit disc images,
the warning has a "Don't show this again" option. Unfortunately, I
can't retroactively add the warning where it's most needed:
in Dolphin 5.0, which does not support Wii NKit disc images.
That a device doesn't have a touchscreen doesn't necessarily mean
that it doesn't support rumble (though it is usually the case).
setPhoneVibrator already contains a check for whether the device
supports rumble, so we can simply remove the touchscreen check.
Fixes a critical regression where 95945a0 made us unable to
start emulation on Android 10 and newer. Android is restricting
direct access to /dev/ashmem starting with the new SDK version,
but we can use the new (and simpler) ASharedMemory API instead.
We have to keep using the /dev/ashmem approach on old versions
of Android, though.
