This fixes the rendering of the scan visor in Metroid Prime 2: Echoes,
as seen in https://fifoci.dolphin-emu.org/dff/mp2-scanner/
The alpha channel was off-by-one on Ivy Bridge due to the rounding
after multiplication with colmat. This commit removes this matrix
altogether in most cases, making them simple GLSL swizzles.
This will generate one shader per copy format. For now, it is the same
shader with the colmat hard coded. So it should already improve the GPU
performance a bit, but a rewrite of the shader generator is suggested.
Half of the patch is done by linkmauve1:
VideoCommon: Reorganise the shader writes.
Currently, a simple typo in the system name will trigger an assert
message that complains about a "programming error". This is not
user friendly and misleading.
So this changes GetSystemFromName to return an std::optional, which
allows for callers to check whether the system exists and handle
failures better.
Manually convert each argument to a UTF-8 std::string, because the
implicit conversion for wxCmdLineArgsArray to char** calls ToAscii
(which is obviously undesired).

Also skips swapping the window system buffers in headless mode, as there
may not be a surface which can be swapped in the first place. Instead,
we call glFlush() at the end of a frame in this case.
Cel-damage uses the color from the lighting stage of the vertex pipeline
as texture coordinates, but sets numColorChans to zero.
We now calculate the colors in all cases, but override the color before
writing it from the vertex shader if numColorChans is set to a lower value.
This was causing an issue where DolphinQt couldn't save graphics options
(DolphinWX doesn't hit this code path), because this function was being
called before the in-memory config was flushed to disk.
With this PR, the in-memory config isn't reset, and only SYSCONF-related
variables may get changed.
7f0834c9 moved the locations of the Real XFB (now XFB to RAM) and
Disabled XFB (now Immediate Mode) settings. There are programs
other than Dolphin that parse DTM headers, so this is not good.
Note that Immediate XFB actually is the inversion of Disabled XFB.
I hope that's not too much of a problem...
All file scope variables are able to be made internally linked.
CD3DFont is essentially used as an extension to the utility interface, so
this is able to be made internal as well, removing a global from
external view.
This lets Dolphin know if a configured GameCube Controller should actually
be treated as connected or not.
Talked to @JMC47 a bit about this last night. My use-case is that all of
my controllers are the same hardware (Xbox One controllers) so share the
same configuration (modulo device number). Treating them all as always
connected isn't a problem for most games, but in some (Smash Bros.) it
forces me to go find a keyboard/mouse and unconfigure any controllers
that I don't actually have connected. Hotplugging devices (works on macOS,
at least) + this patch remove my need to ever touch the Controller Config
dialog while in a game.
This patch makes the following changes:
- A new `BooleanSetting` in `GCPadEmu` called "Always Connected", which
defaults to false.
- `ControllerEmu` tracks whether the default device is connected on every
call to `UpdateReferences()`.
- `GCPadEmu.GetStatus()` now sets err bit to `PAD_ERR_NO_CONTROLLER` if
the default device isn't connected.
- `SIDevice_GCController` handles `PAD_ERR_NO_CONTROLLER` by imitating the
behaviour of `SIDevice_Null` (as far as I can tell, this is the only use
of the error bit from `GCPadStatus`).
I wanted to add an OSD message akin to the ones when Wiimotes get
connected/disconnected, but I haven't yet found where to put the logic.
This is already initialized in the class definition. This would
previously cause a -Wreorder warning on macOS, as m_config is
defined after m_currently_mapped.
Originally, Layer contained a std::map of Sections, which containted a std::map
containing the (key, value) pairs. Here we flattern this structure so that only
one std::map is required, reducing the number of indirections required and
vastly simplifying the code.
We need this because VS currently doesn't consider
std::is_trivially_copyable<typename
std::remove_volatile<SCPFifoStruct>::type>::value
to be true and because no compiler should consider it
to be true if we replace the volatiles with atomics.
No code is relying on this unexplained null byte check, since
the only code that calls UTF16ToUTF8 on non-Windows systems
is UTF16BEToUTF8, which explicitly strips null bytes.
Axis range was previously calculated as max + abs(min), which relies on the assumption that
min will not exceed 0. For (min, max) values like (0, 255) or (-128, 127), which I assume to
be the most common cases, the range is correctly calculated as 255. However, given (20,
235), the range is erroneously calculated as 255, leading to axis values being normalized
incorrectly.
SDL already handles this case correctly. After changing the range calculation to max - min,
the axis values received from the evdev backend are practically identical to the values
received from the SDL backend.
This has no effect now, as we've never bumped the database version.
Instead, it adds future proofing, and makes moving between a future
version with a bump and master clean.
We shouldn't try to create folder names that contain characters
such as : or / since they are forbidden or have special meanings.
(No officially released disc uses such characters, though.)
Now that all inputs are corrected to zero-centered, we can use getFlat()
to ignore movements that are just noise.
This eliminates a lot of drift when the controller is at rest, notably
on the character select screen in Melee.
Android reports the same physical axis multiple times for analog
triggers, and this handles this case.
There are also some controllers with broken mappings (eg the analog
triggers on a PS4 DualShock 4). These axis don't center correctly.
There are also some controllers (again, the PS4) that send both a button
press and an axis movement. This ignores the buttons so we can use the
analog axis. Otherwise, since the button comes before the axis moves
far we would always take the button.
There has been a lot of confusion about what the CPU clock override
section does among users, and looking at it… I’m not surprised! It
doesn’t directly state which CPU clock rate is being overridden!
This small change adjusts the language to clarify that the emulated CPU
is being adjusted.
The main problem was that the volume of the mixer wasn't savestated.
The volume is typically 0 at the beginning of a game, so loading a
savestate at the beginning of a game would lead to silent DTK audio.
I also added savestating to StreamADPCM.cpp.
Nowadays that Dolphin detects regions of discs properly and doesn't
force programs with unknown regions (such as homebrew) into running
under a certain region, the "Force Console as NTSC-J" option is
practically useless for making anything run correctly. Enabling it
is however an easy way to totally break many non-Japanese games.
The earlier code always tried to use TitleDatabase for getting
title names, but that didn't work for disc-based games, because
there was no way to get the maker ID.
Unlike VEN, the endpoint is determined by the value at 8-12.
If it's non-zero, HID submits the request to the interrupt OUT
endpoint. Otherwise, the request is submitted to the IN endpoint.
This commit changes HIDv5 to keep track of endpoints (like IOS does)
and use them when submitting interrupt transfers.
This implements /dev/usb/hid v5, found in IOS57, IOS58 and IOS59.
This is an initial implementation that ignores some differences
with VEN because I lack understanding of what IOS is actually doing
sometimes. These are documented on the WiiBrew article:
https://wiibrew.org/wiki//dev/usb/hid_(v5)
One major difference that this implementation handles is about IDs.
It turns out Nintendo has decided to include the interface number in
the top byte of HIDv5 device IDs, unlike VEN -- even though everything
else about ioctl 1 is otherwise the same!
USBv5 IOS resource managers share most of their code. Some ioctls
are even completely the same! So let's separate the common code
from the VEN specific stuff to make HIDv5 easier to implement.
The descriptor copy code is not actually the same in HIDv4 and VEN,
so it did not make a lot of sense to put it in USB/Common.cpp.
Separate and move it to HIDv4 and VEN.
This cleanup is important because there are even more differences
between HIDv4 and HIDv5.
Fix the device ID struct to reflect the actual structure used by IOS.
It turns out that offset 2 is the internal device index. The reason
that field seemed to be "0x1e - interface_number" is that IOS only
keeps track of 32 devices and always looks for free entries from
the end of the internal array. With each USB interface being exposed
as a separate USBv5 device, "0x1e - interface_number" was mostly
correct... but wrong!
We also made the assumption that the interface number can be
identified from just a USBV5 device ID, which is definitely not true.
VEN (and HID) keep track of the interface number in the internal struct
instead of "reconstructing" it from the device ID (which is normally
not possible if we were generating IDs correctly)
This commit fixes all of these inaccuracies.
Some lines of code in Dolphin just plainly grabbed the value of
g_ActiveConfig.iEFBScale, which resulted in Auto being treated as
0x rather than the actual automatically selected scale.
This reverts commit 1fc910b3ea,
replacing the old INI setting EFBScale with a new INI setting
called InternalResolution, which has a simpler mapping:
| EFBScale | InternalResolution
----------------- | -------------------- | --------------------
Auto (fractional) | 0 |
Auto (integral) | 1 | 0
1x | 2 | 1
1.5x | 3 |
2x | 4 | 2
2.5x | 5 |
3x | 6 | 3
4x | 7 | 4
5x | 8 | 5
6x | 9 | 6
All the fractional IRs were removed in f090a943.
It is not possible to tell whether DLC contents are supposed to be
present on the NAND or not, because they're treated as "optional".
So this commit changes the NAND check to not consider missing
contents for DLC titles as an issue.
"N/A" can be awkward to handle in translations.
I don't think there's much point in showing "N/A" rather than
leaving the description box blank, so let's just leave it blank.
Emulation needs to be running when the surface is destroyed, but we want
to pause in onStop. So call the surfaceDestroyed callback, as this
accomplished both.
The source Views don't need the transition name. We could get the name
from the sharedView via getTransitionName, but since the TV
ImageCardView isn't inflated in XML it would be to be manually set.
I'm not sure if that would be any cleaner than this.
called.
The user will get a brief system popup tutorial the first time it's
used, so we don't need to show them the menu every time. Once they
enable it by pulling down, hide again after 3s.
Use std::string(cstring, strnlen(cstring, max_length)) instead of
trying to remove extra null characters manually, which is a bit
ugly and error prone.
And indeed, the original code contained a bug which would cause
extra NULLs to not be removed at all if the string did not
end with a NULL -- causing issues down the road when constructing
paths for sub-entries.
Because the Wii NAND size is finite, mark titles that were installed
only for booting as temporary, and remove them whenever we need to
install another title (to make room). This is exactly what the
System Menu does for temporary SD card title data.
Also clean up the way the system menu label is updated. We don't want
to access the NAND while emulation is running, and especially not
that many times per second on an unpredictable timing.
This commit removes the last usage of NANDContentManager in IOS code.
Another cleanup change is that loading ARM (IOS) binaries is now done
by the kernel in the BootIOS syscall, instead of being handled as a
special case in the MIOS code. This is more similar to how console
works and lets us easily extend the same logic to other IOS binaries
in the future, if we decide to actually load them.
This removes the hack that enables directly booting from WADs
without installing them first for the following reasons:
1. It makes the NAND content handling much more complicated than what
it should be and makes future changes like permissions or booting
NAND titles without a WAD more annoying to implement.
Because of this hack, we needed an extra level of abstraction
(NANDContent*) which has to read tons of things from the NAND, even
most of the time it's useless. This in turn forces us to have
caching, which is known to break titles and requires manual cache
invalidations. Annoying and error prone.
2. It prevents the WAD boot code from being easily accurate. With this
change, we can simply reuse the existing launch code, and ask IOS
to launch the title from the NAND.
3. The hack did not work that well since it did not cover a lot of ES
commands. And it works even less since the ES accuracy fixes.
This results in Dolphin returning inconsistent results: a
lot of the ES "DI" commands will just fail because the active title
is not installed on the NAND. uid.sys is not changed, etc.
And I'm not even talking about FS stuff -- where this would still
totally fail, unless we add even more unnecessary hacks.
This is not just theoretical -- the system menu and the Wii Shop are
known to behave strangely because the hack damages the NAND
structure, and we've already had several users report issues.
This commit makes it so WADs are always installed prior to launching.
A future commit will remove any code that was there only for the hack.
The GameCube's sample rate is slightly different due to a hardware bug.
The exact numbers are (54000000 / 1124) for GameCube and (54000000 / 1125)
on Wii. I also modified 32KHz mode. This fixes audio desyncs in several
GameCube games and severe issues in Sonic Mega Collection.
