Once nice benefit of fmt is that we can use positional arguments
in localizable strings. This a feature which has been
requested for the Korean translation of strings like
"Errors were found in %zu blocks in the %s partition."
and which will no doubt be useful for other languages too.
The new hash check catches essentially all desync problems
that VolumeVerifier can catch, so from the user's perspective,
such problems will result in Dolphin refusing to start the
game on netplay rather than actually getting a desync.
When I first made VolumeVerifier, I figured that the distinction
between an unsigned ticket and an unsigned TMD was a technical
detail that users would have no reason to care about. However,
while this might be true for discs, it isn't equally true for
WADs, due to the widespread practice of fakesigning tickets to
set the console ID to 0. This practice does not require
fakesigning the TMD (though apparently people do it anyway,
at least sometimes...), and the presence of a correctly signed
TMD is a useful indicator that the contents have not been
tampered with, even if the ticket isn't correctly signed.
It is my opinion that nobody should use NKit disc images without
being aware of the drawbacks of them. Since it seems like almost
nobody who is using NKit disc images knows what NKit is (hmm, now
how could that have happened...?), I am adding a warning to Dolphin
so that you can't run NKit disc images without finding out about the
drawbacks. In case someone really does want to use NKit disc images,
the warning has a "Don't show this again" option. Unfortunately, I
can't retroactively add the warning where it's most needed:
in Dolphin 5.0, which does not support Wii NKit disc images.
The constant DESIRED_BUFFER_SIZE was determined by multiplying the
old hardcoded value 32 with the default GCZ block size 16 KiB.
Not sure if it actually is the best value, but it seems fine.
A small, nonexhaustive set of warning fixes. The DiscIO Volume change
is a workaround for a GCC bug [1] that causes returning an unengaged
std::optional to emit annoying -Wmaybe-uninitialized warnings.
This last change alone fixes pages upon pages of warnings since
Volume.h is included from several files.
-Wstringop-truncation is another irrelevant warning for us, but
unfortunately there seems to be no way to disable it without
adding ugly pragmas wherever the warning appears.
string_view is a thin wrapper around C strings, so it's more efficient
for constant strings than C++ strings.
The unordered_set<> also adds extra runtime overhead. For small arrays,
a simple linear search works. For larger arrays, std::binary_search()
works better than linear but without the unordered_set<> overhead.
ShouldBeDualLayer(): Removed a duplicate "SK8X52" entry.
This happens if someone manually downloads a regular datfile from
redump.org and puts it where Dolphin stores datfiles. Dolphin needs
"special" datfiles that contain fields for serials and versions.
Before this change, all discs (except Datel discs) would show up as
"Unknown disc" when using a regular datfile.
This was making it impossible to use the Redump.org integration
without first manually creating a Redump folder in the Cache folder.
