This is the only way to get Wiimotes working under Android now.
This, just like the Wii U Gamecube Controller Adapter, completely goes around Android's limitations and talks with the device directly through USBManager.
Couple notes.
Continuous scanning must be enabled otherwise the Wiimotes won't be seen.
The UI doesn't expose support for this yet. One must change the Wiimote source and continuous scanning settings manually.
Testing up to two wiimotes in Taiko No Tatsujin, no reason to believe all four won't work.
This is because Google decided it was in their best interest to update eglext.h for android-21/arch-arm only and completely neglect all the other
architectures.
Sucks to suck.
This is being implemented here first under EGL since the infrastructure is already in place for this due to the Android code requiring some bits.
The rest of the interfaces will come in a little bit.
This will be required for threaded shader compiling in the near future.
Clients have no need to send their configuration information on start and the server straight out ignores it.
Not to mention it shouldn't try sending a struct as a null terminated string.
Cleans up how the server sends the configuration slightly as well.
Previously we would iterate through every GC adapter plugged in to the PC and steal ownership of it.
This causes issues all over the place in the implementation if this happens.
Break on the first adapter we can get access to.
The dumb wxAUI stuff isn't fully implemented for GTK. So the wxAuiToolBar doesn't properly deduce the size it needs to be when it contains a
wxSearchCtrl object.
Force the manager to set its minimum size to something reasonable.
No way to properly enable it from an end user perspective yet.
Doesn't require root.
This same sort of system can be used for the Dolphinbar in the future for real wiimote support.
Dolphin has supported the recalibration shortcut (X+Y+Start) for quite a long while. So if someont's axises are terrible, you could easily
recalibrate.
Games even get the initial calibration upon boot(Most of the time).
While changing over the GCAdapter code, I was testing to make sure the reset and calibration shortcuts still worked, turns out they didn't work at
all.
Looking in to the problem, we capture the combination properly, and we wait three seconds until we actually fire that off recalibration.
The problem is for Nintendo's SDK to properly handle recalibrating, we need to send back data saying that it needs to recalibrate.
On hardware this is done as part of the 64bits of data the controller sends back to us.
On holding of the controller, bit 61 of the return value is set, which the Nintendo SDK catches, and then signals immediately afterwards a CMD_ORIGIN
command in order to recalibrate the controller.
We were outright ignoring this bit, so the library wasn't ever recalibrating. I suspect in the past the class itself used to use the calibration data
to to offset the data, but somewhere along the lines it got munged out of existence.
The Gamecube adapter does this shortcut in a bit of a unique way, instead of sending the command and having the library support it and what have you.
Once holding the shortcut for the amount of time, the adapter reports back that the controller has actually been disconnected. Then when you let go of
the combination, the adapter states that a new device has been connected to that port, and the recalibration happens because a new device is
"connected."
This fixes controller calibration for both emulated GC controllers and also the Wii Gamecube Adapter.
The Wii U Gamecube controller adapter setup has always been a bit weird. It tries to be as automatic as possible to make the user experience as easy
as possible.
The problem with this approach is that it brings a large disconnect in the user experience because you have the Gamecube controller setup with regular
gamepads and then for some reason below that you have a "direct connect" option which will cause the Gamecube Adapter to overwrite the regular inputs
if something was connected.
While this works and allows the user to only click one checkbox to get the device working, it breaks the user's experience because they don't really
know what "direct connect" means and won't look it up to figure out what it is. Just expecting the device to work (At least one occurence of this in
the IRC channel in the last week).
This way around also had the terrible nature of making the code more filthy than it needed to be. The GCAdapter namespace was parasitic and hooked in
to the regular GC Controller SI class to overwrite the data that it was getting from the default configuration.
Now instead we have a specific SIDevice class for the Wii U Gamecube adapter. This class is fairly simple and is a child of the regular SI Gamecube
Pad device and only reimplements what it needs to.
This also gives the ability to configure controllers individually, which allows the user to configure rumble individually per pad input.
Overall the code is cleaner, and it fits more in line with how the rest of Dolphin works.
