VolumeDirectory doesn't support necessities like TMDs,
so thanks to 5.0-2172 (18968ab), EmulatedBS2_Wii crashes
when the inserted disc is a VolumeDirectory.
This commit fixes that.
This commit makes our DOL booting code very similar to our
ELF booting code. One exception is that the DOL booting
code still always calls SetupBAT. (Note that EmulatedBS2_GC
calls SetupBAT even if no disc is inserted.) I'm not sure
if there's a point to the difference, but I thought I'd
better avoid changing it so that I don't break anything.
For thread safety reasons, the currently inserted volume must
only be accessed by the DVD thread (or by the CPU thread if it
calls DVDThread::WaitUntilIdle() first). After this commit,
only DVDThread.cpp can access the volume, which prevents code in
other files from accessing the volume in a non-threadsafe way.
Direct access to the WAD bytes is required to read contents with proper
padding data (since they can sometimes end up being outside of the
data app section). Allowing the whole buffer to be accessed directly
would be error prone, so this commit adds GetContent() to WiiWAD
for getting raw content data by index.
These cannot be booted, so it is bad UX to show them in the UI as if
they were regular titles, and yet have different behaviour for them.
And technically, there is no reason to allow them to be used to boot
in the first place.
Another reason they should not be shown is that Dolphin fails
spectacularly with WADs that have a valid boot content index, but are
not PPC titles (e.g. IOS WADs). The only reliable way to avoid this
is to check for the title type and only show channels, just like
the Wii System Menu.
Mistakenly used the wrong TMD to clean up the import.
The original TMD is the one that is supposed to be used when
cancelling an import, but I forgot it's in the /import directory after
starting an import.
This exposes all ES title management ioctlvs to avoid duplicating IOS
code everywhere and to make it easier to reuse (since this way it's
not unnecessarily tied to the PPC IPC mechanism anymore) and unit test.
Some functions were also renamed for consistency with the other names,
*and* with official names.
It's better to just let the calling code provide a volume
object instead of needing one SetVolume for each way of
creating a volume. This simplifies InsertDiscCallback and
is needed for the following commits.
