This adds a function to get the emulated or real Bluetooth device for
an active emulation instance. This lets us deduplicate all the
`ios->GetDeviceByName("/dev/usb/oh1/57e/305")` calls that are currently
scattered in the codebase and ensures Bluetooth passthrough is being
handled correctly.
This also fixes the broken check in WiimoteCommon::UpdateSource.
There was a confusion between "emulated Bluetooth" (as opposed to
"real Bluetooth" aka Bluetooth passthrough) and "emulated Wiimote".
When a save state is loaded, the IOS device serving bluetooth
is cast as BluetoothEmuDevice. If, however, a real Wiimote
with BT passthrough is used, this caused the game to crash.
Now the proper device class is used.
21c152f added a small hack to DVDInterface to keep WBFS and CISO
files working with Nintendo's "Error #001" anti-piracy check.
Unfortunately I don't think it's possible to support WBFS and
CISO without any kind of hack or heuristic, but what we can do
is replace the 21c152f hack (which applies regardless of file
format) with a hack that only is active when using WBFS or CISO.
This change is similar to 2a5a399, but the disc size is
calculated in a different way.
Whether the custom RTC setting is enabled shouldn't in itself
affect determinism (as long as the actual RTC value is properly
synced). Alters the logic added in 4b2906c.
I'm not entirely certain that this is correct, but the current
code doesn't really make sense to me... If we need to force the
RTC bias to 0 when custom RTC is enabled, why don't we need to
do it when custom RTC is disabled? The code for getting the
host system's current time doesn't contain any special handling
for the guest's RTC bias as far as I can tell.
When reading a reply from a message sent to the data socket there is
the possibility that the other side gets sent multiple messages
before replying to any of them, which can lead to multiple replies
sent in a row. Though this only happens when things time out, it's
quite possible for these timeouts to happen or build up over time,
especially when initiating the connection.
This change makes sure to flush any pending bytes that have not been
read yet out of the socket after a successful POLL reply is received,
since that is the most common time when backups occur, and as well as
using the exact number of bytes in an expected reply, to ensure
the received data and the message it's replying to do not get out of
sync.
Some of the device names can be ambiguous and require fully or partly
qualifying the name (e.g. IOS::HLE::FS::) in a somewhat verbose way.
Additionally, insufficiently qualified names are prone to breaking.
Consider the example of IOS::HLE::FS:: (namespace) and
IOS::HLE::Device::FS (class). If we use FS::Foo in a file that doesn't
know about the class, everything will work fine. However, as soon as
Device::FS is declared via a header include or even just forward
declared, that code will cease to compile because FS:: now resolves
to Device::FS if FS::Foo was used in the Device namespace.
It also leads to having to write IOS::ES:: to access ES types and
utilities even for code that is already under the IOS namespace.
The fix for this is simple: rename the device classes and give them
a "device" suffix in their names if the existing ones may be ambiguous.
This makes it clear whether we're referring to the device class or to
something else.
This is not any longer to type, considering it lets us get rid of the
Device namespace, which is now wholly unnecessary.
There are no functional changes in this commit.
A future commit will fix unnecessarily qualified names.
