This implementation is different from Luma3DS's which directly hooks the SDK functions. Instead, we read the RomFS's metadata and figure out the directory and file structure. Then, relocations (i.e. replacements/deletions/patches) are applied. Afterwards, we rebuild the metadata, and assign 'fake' data offsets to the files. When we want to read file data from this rebuilt RomFS, we use binary search to find the last data offset smaller or equal to the given offset and read from that file (either from the original RomFS, or from replacement files, or from buffered data with patches applied) and any later files when length is not enough.
The code that rebuilds the metadata is pretty complex and uses quite a few variables to keep track of necessary information like metadata offsets. According to my tests, it is able to build RomFS-es identical to the original (but without trailing garbage data) when no relocations are applied.
The DIGIT filter was incorrectly implemented as preventing all digits. It actually limits the maximum digit count to max_digits, according to ctrulib and hardware testing.
- We have some important audio settings, makes them more discoverable.

Until we get a on screen display or async shader loading, we should at
least have some measure of progress in the meantime. This is 90% a port
from the loading screen I made for yuzu, but with a slightly different
changed detection for when to display the ETA. Now we keep track of a
rolling estimate for shader load ETA and only display a ETA if its going
to take longer than 10 seconds.
This is based on what was done using additional layouts, but modified
to have a variable to control rotation and making it so Single Screen
Layout behaves like Upright Single would, and Default Layout behaves
like Upright Double would, when the new variable is used.
Large Layout and Side Layout currently ignore the new variable.
New variable still currently doesn't have a hotkey.
The BPS format allows distributing patches that are smaller and that do
not contain copyrighted content if data is relocated
(unlike non-trivial IPS patches).
This is essential for games such as MM3D that have three barely
different code revisions. Supporting all three versions would
demand an unreasonable amount of work; with BPS patches only one
version has to be supported.
This changes ApplyCodePatch to return a ResultStatus, which makes it
possible to determine whether patch applying has failed. Previously,
only a boolean was returned, and false was returned when no patch
was found OR when a patch was found but applying it failed.
This also changes AppLoader_NCCH to return an error if patching fails
because the executable is likely to be left in an inconsistent state
and we should not proceed booting in that case.
This significantly reduces unnecessary disk writes and space usage
when building Citra.
libcore.a is now only ~1MB rather than several hundred megabytes.
Previously we would first attempt to use any buffer that was free,
meaning whichever buffer has already been displayed. This has poor
interactions when the operating system throttles the update rate of the
window, so if there isn't any free buffers available, just reuse the
oldest frame instead.
Simple cut/paste issue where initialized is only set to true when the
emulation attempts to init the Binary Pipe, but we used it to test if
the FFMPEG decoder was valid and disabled it if it wasn't. Just return
the value of have_ffmpeg_dl instead so when dynamic loading is added
it'll still work.
HACK
In Luigi's Mansion Dark Moon in HLE audio, the game mysteriously passes
in an extremely large value for length, which without any checks, causes
HLE audio to allocate an extremely large buffer.
This value seemingly is caused by some other HLE audio feature is missing,
and Luigi's Mansion subtracts two values to get a length, without
checking for overflow first. This appears to be caused by an incorrect
HLE audio emulation, as its fixed entirely by only changing to LLE. As
such, further investigation is required, but in the meantime, completely
eating up our users RAM is unacceptable.
The text shared memory wasn't supposed to be cleared according to my comparison with the LLE swkbd. This can cause issues in certain games such as Harvest Moon.
A null terminator is added to the text copied to mark the end of the string.
Fixes an issue where the touch point is incorrect in OpenGLWindow when the render
target is initialized for the first time with single window mode disabled.
While QOpenGLWidget sounds like a good idea, it has issues which are
harder to debug due to how Qt manages the context behind the scenes. We
could probably work around any of these issues over time, but its
probably easier to do it ourselves with a QWindow directly.
Plus using QWindow + createWindowContainer is the easiest to use
configuration for Qt + Vulkan so this is probably much better in the
long run.
Over time our config values have grown quite numerous in size.
Unfortunately it also makes the single functions we have for loading and
saving values more error prone.
For example, we were loading the core settings twice when they only
should have been loaded once. In another section, a variable was
shadowing another variable used to load settings from a completely
different section.
Finally, in one other case, there was an extraneous endGroup() call used
that didn't need to be done. This was essentially dead code and also a
bug waiting to happen.
This separates the section loading code into its own separate functions.
This keeps variables only visible to the code that actually needs it,
and makes it much easier to visually see the end of each individual
configuration group. It also makes it much easier to visually catch bugs
during code review.
While we're at it, this also uses QStringLiteral instead of raw string
literals, which both avoids constructing a lot of QString instances, but
also makes it much easier to disable implicit ASCII to QString and
vice-versa in the future via setting QT_NO_CAST_FROM_ASCII and
QT_NO_CAST_TO_ASCII as compilation flags.
We relies on UNREACHABLE's noreturn attribute to eliminate parent's "no return value" warning. However, this was wrapped in a `if(!false)` block, which compilers may not unfold to recognize the noreturn nature.
By default, DisplayRole is used as the SortRole.
This behaviour is what's expected by the user.
Made it so that an access to SortRole is equivalent to one to DisplayRole.
Also fixes a bug with directory sorting.
Also fix a small issue with incorrect shutdown ordering in SDL.
Previously the system would still be running so the telemetry task
didn't launch and detached_tasks would assert(count == 0)
Fixes a regression from #4862, which caused the NCCH title ID checking
heuristic to be skipped whenever the exheader is replaced.
I was thinking the heuristic wouldn't be needed in that case, but it
turns out that many users still have pathological NCCHs that indicate
they are encrypted but are actually decrypted...
Now the original exheader is always read and used for the heuristic
to determine whether the NCCH is actually encrypted; only then do we
load a replacement exheader (if it exists) to avoid affecting the
heuristic.
This single line mode is aimed at restoring the intended behavior with Small or None icons. Line breaks will be replaced with commas (Region row) or spaces (Name row). One can toggle this option in UI configuration.
This option was intended for enabling optimizations when all rows are granted to have the same height. In our case this is not true, and therefore the behavior is actually undefined. Different versions of Qt handle this differently. Newer versions of Qt tend to hide contents that are too big in height, which goes against our wishes. Thus, it's probably the best to disable this option so that things don't go wrong if we ever decide to update Qt.
Some titles (mostly homebrews) do not use the region free value 0x7FFF but instead set all of the region flags, resulting in all regions displayed in game list, which is not beautiful and not what we want. This fixes it by adding an all_regions check.
Separate options are now provided for FFmpeg AAC audio decoder and FFmpeg video dumper. This allows users to configure Citra with greater freedom.
Also, previously for Linux builds, AAC decoder is accidentally enabled along with the dumper, which could potentially cause patent issues (?). This commit fixes it by only enabling video dumper.
This widget provides a simple list of recorded requests as well as a simple filter and the 'Clear' button. Requests with status 'HLE Unimplemented' or 'Error' will be marked out with the red color.
This widget handles retrival of service name. For reasons refer to a previous commit message.
Added the widget to the Debugging menu, pretty much the same as other debugging widgets.
This is for displaying the service names. This function is only used in the frontend, because Recorder which is in the Kernel cannot and should not have access to SM in the System.
Pretty much the same as LLE requests, the 'translate' part is chosen. A function is added to the context class to record requests that involves unimplemented HLE functions.
The 'translate' function is a great place to put this in IMO as it is possible to get both untranslated and translated cmdbufs. However a kernel reference has to be passed here, but it is not too hard fortunately.
This class resides in Kernel mainly because that, it's hard for kernel objects to get references to the System (and therefore to the Recorder), while much easier for KernelSystem. If this is to be moved to System the code will likely get much more complex with System (or Recorder) references passed everywhere.
This is for displaying the function name for HLE requests. Probably it is possible to do the same for LLE ones but it would require having the HLE handlers available even when not using them, which doesn't seem to make sense and is more of a hack than a proper solution in my opinion.
Added a new state amiibo_in_range. This state is akin to the real world
physical relationship between a 3DS machine and an amiibo, which is
independent from the service state (or even the machine is powered on or
not). The service state nfc_tag_state is then synchronized with this
physical state on every potential point when the state changes. This
solves the issue where user might load an amiibo before NFC service
initializes, or remove an amiibo after NFC service shutdown, which
previously causes inconsistent state change.
Also removed std::atomic on nfc_tag_state, because
1. It is already protected by g_hle_lock
2. It wasn't properly used in the code anyway. For example, there are
many double loading on this variable, which effectively make it
non-atomic.
Previously, telemetry results couldn't give a good estimate for
performance over time, because it didn't include any fields related to
performance. With this, devs should be able to query metabase for mean
frametime to check for performance regressions after a change is made.
For better tracking of performance regressions on incoming changes, this
change adds a way to dump frametime to file by changing an ini config
option. This is intentionally hidden as its only useful to a small
number of individuals, and not really applicable to the general
userbase.
Two PBOs are used to speed up pixel copying process. To avoid getting the wrong speed/FPS, a new parameter is added to DrawScreens about whether to increase the frame count.
The speed limiter being a frame limiter is an implmentation detail and can be changed in the future. What user care about is that it limit the emulation speed in genenral (not just graphics but also audio+input)
* yuzu/about_dialog: Specify string conversions explicitly
Specifies the conversions explicitly to avoid implicit conversions from
const char* to QString. This makes it easier to disable implicit QString
conversions in the future.
In this case, the implicit conversion was technically wrong as well. The
implicit conversion treats the input strings as ASCII characters. This
would result in an incorrect conversion being performed in the rare case
a branch name was created with a non-ASCII Unicode character, likely
resulting in junk being displayed.
* yuzu/main: Move window title updating logic to its own function
For similar reasons to the previous change, we move this to a single
function, so we don't need to duplicate the conversion logic in several
places within main.cpp.

Require and assume that override exheaders are decrypted for
consistency with Luma's loader behaviour and to ensure consistent
behaviour regardless of whether the NCCH is marked as encrypted or not.
Currently, exheader overriding with an encrypted NCCH would cause
the title ID checking heuristic to mistakenly disable encryption,
which would then make exefs loading fail.
Allows the configuration code to build successfully with implicit string
conversions disabled.
Also makes default_hotkeys internally linked:
Given the array is a private static array, we can just make it
internally linked to hide it from external code. This also allows us to
remove an inclusion within the header.
* yuzu/bootmanager: Remove unnecessary pointer casts
We can just invoke these functions by qualifying the object name before
the function.
* yuzu/bootmanager: unsigned -> u32
Same thing (for platforms we support), less reading.
* yuzu/bootmanager: Default EmuThread's destructor in the cpp file
This class contains non-trivial members, so we should default the
destructor's definition within the cpp file.
* yuzu/bootmanager: Treat the resolution factor as a u32
Treating it as a u16 can result in a sign-conversion warning when
performing arithmetic with it, as u16 promotes to an int when aritmetic
is performed on it, not unsigned int.
This also makes the interface more uniform, as the layout interface now
operates on u32 across the board.
* yuzu/bootmanager: Log out screenshot destination path
We can make this message more meaningful by indicating the location the
screenshot has been saved to. We can also log out whenever a screenshot
could not be saved (e.g. due to filesystem permissions or some other
reason).
* Fix compilation
This allows an IPS patch to edit .bss. This is useful for game patches
that need to add code, as putting things in .bss allows adding new code
*without* editing .code and thus without having to relocate everything.
Previously we were building with MBCS, which is pretty undesirable. We
want the application to be Unicode-aware in general.
Currently, we make the command line variant of yuzu use ANSI variants of
the non-standard getopt functions that we link in for Windows, given we
only have an ANSI option-set.
We should really replace getopt with a library that we make all build
types of yuzu link in, but this will have to do for the time being.
Enforces the use of the proper URL resolution functions. e.g.
url = some_local_path_string;
should actually be:
url = QUrl::fromLocalPath(some_local_path_string);
etc.
This makes it harder to cause bugs when operating with both strings and
URLs at the same time.
Other overloads of start() are considerably much safer to use if we ever
need this in the future and need to pass arguments to the program, given
it contains separate parameters for the program path and the arguments
themselves, whereas this unsafe overload contains both as a single
string.
Given the alternatives are much safer, we can disable this.
Currently, having a replacement code.bin causes Citra to crash as it is
trying to load icon data from code.bin because of a typo. This commit
fixes that typo.
This attempts to fix segfault in some tests where page table is set before initializing cpu core (intended behaviour? might be worth a check...)
see: src/tests/core/arm/arm_test_common.cpp
see: src/tests/core/arm/dyncom/arm_dyncom_vfp_tests.cpp
It will both change the page table in memory and notify the CPU about the change by itself. This way there is no need to call memory.SetCurrentPageTable() when kernel.setCurrentProcess() and the management is kept internally in the kernel
By default, MSVC doesn't use standards-compliant volatile semantics.
This makes it behave in a standards-compliant manner, making
expectations more uniform across compilers.
