The old implementation always polled the local 1st Wiimote and used that as input for the Wiimote that is mapped to the player. But the reporting mode for Wiimotes can be different, even when using the same extensions. So an input for Wiimote 1 with a data size 4 could be used for Wiimote 2, which actually requires data size 7 at that time for example.
The 2nd problem was that the code added a dummy input into the buffer, when the reporting mode changed. But when the data from the other player hasn't arrived yet, the data in the buffer is out of order. Well, i think this is the problem, i'm not 100% sure, because i don't fully understand how the buffer works. But on the other hand, i'm pretty sure this will just force sync the players on reporting mode changes, instead of allowing them to be apart.
Pros:
- No more desyncs caused by big bugs in the code.
- Can use different extensions for different players.
Cons:
- Higher latency, because instead of polling 1 controller per player at once, all controllers are polled in order, send to the other players, before the next is processed.
- Have to setup the Wiimote, which the player is going to use, instead of the 1st one.
Now, if the controller config could temporarily be overridden with the one from another slot, the 2nd problem could be fixed. But at the same time, we would lose the ability to use different extensions. (unless we hack around it somehow, or properly send the used extension to the other players)
Specifically, don't make any assumptions about what effective addresses
are used for code, and correctly handle changes to MSR.DR/MSR.IR.
(Split off from dynamic-bat.)
This makes the device ID assigning code common to all backends, by
moving it to AddDevice() instead of copy-pasting or replicating
the logic in the backends.
Also, to prepare for hotplugging, instead of relying on a name usage
count, the new ID assigning system always starts from ID 0 and tries
to assign the first ID that is not used.
At first there weren't many enums in Volume.h, but the number has been
growing, and I'm planning to add one more for regions. To not make
Volume.h too large, and to avoid needing to include Volume.h in code
that doesn't use volume objects, I'm moving the enums to a new file.
I'm also turning them into enum classes while I'm at it.
CScript must be run as 64-bit regardless of the MSBuild bitness. Otherwise it won't find 64-bit Git installations.
However the "Sysnative" redirector is not available for 64-bit processes. So a fix is needed when 64-bit MSBuild is run.
The "ProgramFiles(x86)" Macro is only set for 64-bit, otherwise it is empty. Therefore it can be used as condition to check whether the current MSBuild process is 32 or 64-bit.
This moves back the WiimoteScanner:Update() call to where it originally
was, since according to a comment it is intended to be called only when
"when not looking for more Wiimotes", and calling it too often causes
the Bluetooth module to be loaded/unloaded a lot of times.
The Setting class was used for both numeric values and booleans, and
other parts of the code had hacks to make it work with booleans.
By splitting Setting into NumericSetting and BooleanSetting, it is
clear which settings are numeric, and which are boolean, so there is
no need to guess by checking the default values or anything like that.
Also, booleans are stored as booleans in config files, instead of 1.0.
The values are expected to be in the 0.0-1.0 range (as indicated by the
comment), and other parts of Dolphin also expect it to be in that range
since the "full" axis has a -1.0 to 1.0 range. However, this is not
always the case and fvalue can end up being outside of the range. This
clamps fvalue to always be in the 0.0 and 1.0 range.
- Externals/soundtouch/CMakeLists.txt: add -w (since it's not our code) to
silence an unused variable warning
- Source/Core/Core/NetPlayClient.cpp: Work around a Clang/libc++ bug where
initializing a std::array the way the standard says you're supposed to produces
a warning. (libc++'s implementation of std::array, like any sane
implementation, has a C array as a field, so the most explicit form of
initialization would use two braces, one for the struct and one for the array.
Clang has a general warning for not being explicit with braces, which is
usually sane. But the standard only guarantees that initializing std::array
works with a single pair of braces!) There are other places in Dolphin that
incorrectly use double braces, presumably to avoid the warning, so maybe the
warning should just be turned off, but in any case here I just switch to an
equivalent .fill().
