The current implementations do many things wrong but work well enough to
run the Dragon Quest X installer until the very end. The game itself
crashes when being launched from its System Menu channel unfortunately
so it is hard to verify whether the install properly worked or not.
There are plenty of "TODO(wfs)" sprinkled around this codebase with
things that are knowingly done wrong. The most important one right now
is that content extraction is done by buffering everything into memory
instead of properly streaming the data to disk (and processing
asynchronously), which causes freezes. It is likely to not cause any
practical issues since only the installer and the updater should use
this anyway.
Without this, attempts to savestate std::set will fail with an error
about dropping the const qualifier.
<Lioncash> leoetlino: I'll try to break it down: So, when you do a
ranged-for on a container, it's essentially syntactic sugar over begin
and end iterators. std::set is an associative container where the key
type is the same as the value type, and so it's required that all
iterator functions return constant iterators. If this wasn't a
requirement, it would allow changing the ordering of elements from
outside of the set's API (this is bad).
This attempts to make some bit arithmetic more self-documenting and also
make it easier during review to identify potential off-by-one errors by
making it possible to just specify which bits are being extracted.
Functions both support the case where bits being extracted can vary and
fixed bit extraction. In the case the bits are fixed, compile-time asserts
are present to prevent accidental API usage at compile-time.
e.g. Instead of shifting and masking to get bits 10 to 15,
Common::ExtractBits<10, 15>(value) can just be done instead.
There are several things wrong with this implementation. The first being
that since we still don't have a proper ticket/tmd handling library, we
hardcode offsets once again to fetch TMD fields. The second being that
we don't stream data to the disk and we buffer everything in memory. The
third being that we don't properly fetch the content index for
decryption, which is prone to breaking.
But hey, it works well enough to install the DQX channel!
This library implements basic parsing support for some of the IOS ES
formats we need to extract data from. Currently only implements TMD
functions, but some ticket handling functions from DiscIO should likely
be moved here in the future.
These two functions load either a signed ticket or a raw ticket from the
emulated NAND.
The ticket signature skip is refactored out of the ticket writing in
order to be usable by the raw ticket reading function.
Refactor the existing DiscIO::AddTicket to not require the caller to
pass the requested title ID. We do not have the title ID in the ES case,
and it needs to be extracted from the ticket. Since this is always a
safe operation to do (title ID is always in the ticket), the
implementation is made default.
This constant isn't particularly helpful, mainly because it's not
applicable to all DSP instructions. Some instructions don't have encoding
space for registers, and not all instructions that do encode registers
have one at the first five bits.
This change also has the benefit of removing all includes to the
interpreter within the JIT code, which keeps them fully separate from one
another. Changes to the interpreter header won't require some of the JIT
code to be rebuilt.
Dolphin is able to generate one with all correct default settings, so
we don't need to ship with a pre-generated SYSCONF and worry about
syncing default settings.
Additionally, this commit changes SysConf to work with session SYSCONFs
so that Dolphin is able to generate a default one even for Movie/TAS.
Which SYSCONF needs to be touched is explicitly specified to avoid
confusion about which file SysConf is managing.
(Another notable change is that the Wii root functions are moved into
Core to prevent Common from depending on Core.)
