The old implementation of this was not able to distinguish between
a title that had the common key index set to 1 because it actually
was Korean and a title that had the common key index set to 1 due to
fakesigning. This new implementation solves the problem by
decrypting a content with each possible common key and checking
which result matches the provided SHA-1 hash.
The problem that the old implementation causes has only been reported
to affect a certain pirated WAD of Chronos Twins DX (WC6EUP), but it's
possible that the problem would start affecting more WADs if we add
support for the vWii common key (which uses index 2). Adding support
for the vWii common key would also prevent us from using the simpler
solution of always forcing the index to 0 if the title is not Korean.
...in addition to the existing function CreateVolume
(renamed from CreateVolumeFromFilename).
Lets code easily add constraints such as not letting the user
select a WAD file when using the disc changing functionality.
This lets us convert CalculateVertexElementSizes() from a function using
an out pointer into one that simply returns the array data as a return
value.
It also lets us dehardcode some values, as we can just query
std::array's size() member function instead.
At its only usage point, its return value is stored into a u32, and the
default implementation returns 0xFFFFFFFF (-1), which would be an
unsigned integer. Given all of the bits are used to determine a color,
it makes slightly more sense to treat this as an unsigned value as
opposed to a signed one.
We're allowed (by the standard) to forward declare types within
std::vector, so we can replace direct includes with forward declarations
and then include the types where they're directly needed.
While we're at it, we can remove an unused inclusion of <cstring>, given
nothing in the header uses anything from it. This also revealed an
indirect inclusion, which this also resolves.
Previously u32 was being used for part of the interface and unsigned int
was being used for other parts. This makes the interface fully consistent by
using only one type.
We opt for u32 here given they communicate the same thing (for platforms
we care about where int is 32-bit), while also being less to read.
While we're at it, we can also default the constructor and destructor of
inheriting classes in their respective cpp file to prevent the
construction and destruction of non-trivial types being inlined into
other regions of code.
This was in DolphinWX but not DolphinQt. It's useful for telling if
users who post screenshots have an up-to-date version of Dolphin.
The old implementation of this prepended the version in DolphinWX code
rather than Core code, but I thought it'd be simpler to do it in Core.
IOLinux.cpp should include <sys/select.h> as it uses select() functionality.
On certain platforms it's included implicitly by other headers, which is why
it compiled before. This makes it also work on musl platforms.
libusb transfer callbacks might be called immediately during transfer
submission in some cases. (libusb doesn't even specify what thread
the callback is invoked on.) In other words, it is possible to reach
the transfer callback from the CPU thread, and not just from the
USB event handling thread.
So CoreTiming::FromThread::NON_CPU is incorrect and should instead
be ANY.
