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.
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.
This updates the maker data to (mostly) mirror that of the Wiki:
https://wiki.dolphin-emu.org/index.php?title=GameIDs
Only maker ids from that page are now included in Dolphin. This
means no homebrew/unofficial makers.
Also, separate multiple maker names with a slash
