Dolphin assumes that content 0 is opening.bnr, without checking
whether content 0 exists or if it is even supposed to be there (it's
only there for channels). This results in sometimes reading garbage.
This adds a check to only try to read names from content 0's header
if the title is a channel (channel, system channel or game channel).
The Tools > Load System Menu option displays the version of the
installed Wii Menu. This commit changes the way we display that
version, like so: "Load System Menu 514P" -> "Load System Menu 4.3E"
The numbers are from http://wiibrew.org/wiki/System_Menu
5.0-2712 made ES's code for setting the game ID use the
title ID converted to hex (except for disc titles) instead
of using a 6-char game ID like before. Then, 5.0-2830 made
us use that code even when loading game INIs. This breaks the
expectations of both users and the game INIs we ship with.
This commit makes Dolphin use 6-char game IDs for all
titles (unless the 6-char ID would contain unprintable
characters, which is the case with e.g. the Wii Menu).
I'm also putting unprintability checks in VolumeWad
for consistency.
Advantages:
* Simpler code in general
* No extra volume objects created
* Now actually notices if the disc or partition gets
changed while the core is running
* No longer picks up on disc access done by the GUI
(it used to do so as long as the core was running)
* Gets rid of a Core dependency in DiscIO
There are two performance disadvantages:
* FileMonitor is now a bit slower when used with VolumeDirectory
because FileMonitor now always uses the FileSystemGCWii code
for finding filenames instead of VolumeDirectory finding the
filename on its own and directly hooking into FileMonitor.
But this isn't such a big deal, because it's happening on the
DVD thread, and my currently unmerged file system PR will make
FileSystemGCWii's file finding code about as fast as
VolumeDirectory's.
* FileMonitor's creation of the file system object is now
done on the CPU thread instead of the DVD thread, and
it will be done even if FileMonitor logging is disabled.
This will be fixed in the next commit.
There's no point in creating a volume without a blob,
since essentially all the functionality of a volume
requires a blob to be used.
Also, VolumeCreator doesn't support creating volumes
without blobs (it can't even figure out the volume type
unless it gets a blob), so it's currently impossible
for a volume to be created without a blob.
Most of the Volume code was written before this
convenience function was added. Let's use it more.
Also deleting m_pReader nullptr checks that are
unnecessary because of Read (which ReadSwapped calls)
already having a nullptr check.
This moves all the byte swapping utilities into a header named Swap.h.
A dedicated header is much more preferable here due to the size of the
code itself. In general usage throughout the codebase, CommonFuncs.h was
generally only included for these functions anyway. These being in their
own header avoids dumping the lesser used utilities into scope. As well
as providing a localized area for more utilities related to byte
swapping in the future (should they be needed). This also makes it nicer
to identify which files depend on the byte swapping utilities in
particular.
Since this is a completely new header, moving the code uncovered a few
indirect includes, as well as making some other inclusions unnecessary.
This changes ES to keep track of the active title properly,
just like IOS:
* It is NOT changed on resource manager open/close.
* It is reset on IOS reload.
* It is changed by ES_DIVerify and ES_Launch.
IOS stores the active title in a structure like this:
struct ESTitleContext
{
Ticket* ticket;
TMD* tmd;
u32 active;
};
With this commit, we also do keep the Ticket and TMD around. This
makes some of the DI ioctlvs (which return data about the current
active title) trivial to implement in the future.
This fixes the System Menu not being able to see update partitions
and also allows us to change Dolphin's active game info in the future.
We already have a TMDReader, so let's actually use it.
And move ESFormats to IOS::ES, since it's definitely part of IOS.
This adds a DiscIO dependency on Core which will be fixed in a
follow-up PR.
This prevents Dolphin from writing to /sys/uid.sys (on the host; root
partition) when installing a WAD before starting emulation, because
the session root is not initialized at that moment.
Incidentally, this also gets rid of a singleton.
This fixes a regression from 5.0-1556, but I don't know why
the regression occurred or why this fixes it. (Many games
failed to fully boot - I tried Metroid Prime and Twilight
Princess (both GC), and they never got to the title screen.)
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.
Instead of needing different switch cases for
converting countries to regions in multiple places,
we now only need a single country-to-region switch case
(in DiscIO/Enums.cpp), and we get a nice Region type.
We can't rely on the OS returning files and directories
in a deterministic order, so we should sort them on our own
if we want VolumeDirectory to work for movies and netplay.
These disc images are encrypted and signed using a different set of keys.
We only care about the master key, so we check the signature issuer. If
it matches the debug issuer, then we'll use the RVT-R key. Otherwise,
the previous set of common and Korean keys are used.
This would previously fail to compile when included in files that do not
include FileUtil.h due to lack of a type declaration.
This moves the constructor and destructor into the cpp file in order to
satisfy the requirements of unique_ptr construction and deletion. That is,
unique_ptr requires a concrete type at the point of construction and
destruction. If the constructor or destructor is left in the header, then
at the point of construction or destruction, IOFile will still be
considered an incomplete type, as unique_ptr's deleter will still only be
able to see the forward declaration, which it can't use.
These functions don't actually depend on any state from the class
instance, so they don't really belong in the header, and are just
an implementation detail.
At first there weren't many enums in Volume.h, but the number has been
growing, and I'm planning to add one more for regions. To not make
Volume.h too large, and to avoid needing to include Volume.h in code
that doesn't use volume objects, I'm moving the enums to a new file.
I'm also turning them into enum classes while I'm at it.
If banner loading fails once, it will very likely fail again.
Setting m_banner_loaded to true when banner loading fails
prevents LoadBannerFile from wasting time if it's called again.
Banner loading requires loading the file system, which takes a
noticeable amount of time, so this matters.
DriveReader::m_size was never initialized which was indirectly
causing CGameListCtrl to crash Dolphin when it tried to insert a
character at a negative index in a string.
Reading one sector at a time is very inefficient and appears to
be causing timing issues during boot so SectorReader has been
enhanced to support batching.
SectorReader has been given a working cache system.
instead, leave all the management with the NANDContentLoader.
for file data (directly on the NAND), this opens the file on-demand and
returns the requested chunk when asked for it.
for on-the-fly decrypted WAD data, we just keep the decoded buffer in
memory, like we've done before - except that we don't give away any objects
we don't want to.
Using the XPM format for images has become a maintenance problem because
people don't know how to create them. This commit removes all XPM images
and all C files that contain PNG images. DolphinWX now uses the PNGs
in the Resources folder instead, just like DolphinQt and DolphinQt2 do.
Callers can now check whether reads fail, either by checking the return
value or by setting the buffer to a known bad value and seeing if it stays
untouched. I've added error checks to FileSystemGCWii and Boot_BS2Emu,
but not to Boot since it doesn't check any of its other reads either.
Rather than rely on the developer to do the right thing,
just make the default behavior safely deallocate resources.
If shared semantics are ever needed in the future, the
constructor that takes a unique_ptr for shared_ptr can
be used.
If a disc image is malformed in a specific way, Dolphin
will try to allocate a lot of memory, making it crash.
To avoid that, this change adds an artificial limit for
the size of file systems that Dolphin will try to load.
The offset in a directory FileInfo is an FST offset, not a disc offset.
Treating it as a disc offset doesn't make sense. Directories don't take
up space outside of the FST, so they don't need to be marked as used. The
old behavior may have prevented some scrubbable areas from being scrubbed.
It's used by both the GUI to do things like install WADs and check up on
the system menu, in which case the global root should be used, and by
/dev/es, in which case the local one should. The latter isn't
*terribly* useful today, since no contents will ever be installed in
temporary roots (although it's still relevant for data directories), but
converting the whole thing makes sense because then it will Just Work
once the entire NAND is synced.
Because it would have been a bit of work to split it up (but I can if
desired), this commit also contains some basic cleanup of
NANDContentLoader:
(1) The useless interface class INANDContentLoader is removed and the
methods are changed to just return CNANDContentLoader (the only
implementation);
(2) CNANDContentManager is changed to use unique_ptr and cleaned up a
bit.
04fcb72 fixed an issue with reading the Wii FST size, but I found a second
issue when working on PR #2820 - the size must be shifted left by 2.
DiscScrubber and Boot already do this correctly using separate code.
read_size remained 0 when the "Read beyond end of disc" error occurs,
which made the while (nbytes) loop never end. As a fix, SeekToCluster
now explicitly sets available to 0 when the error occurs, and Read
checks for it.
GC games with long names store two variations of the name in
opening.bnr. This makes the shorter of those names available.
For volumes other than GC discs, prefer_long is ignored.
ISOFile and GameFile were using IsWiiDisc() and IsWadFile() to set
an enum value. The volume might as well return an enum directly.
I increased the Qt CACHE_REVISION because m_platform now is saved as u32
instead of int, but increasing the wx CACHE_REVISION is not necessary.
I tried to change messages that contained instructions for users,
while avoiding messages that are so technical that most users
wouldn't understand them even if they were in the right language.
