c5fa470 made the extension check discard directories, but
only in the new code that currently only is used on Windows.
Let's add an equivalent check in the old code so that the
behavior is consistent across platforms.
This seems like an oversight in the old code, because
what's the point of loading user files if the titles
in them are going to be ignored for nearly all games?
This commit fixes the issue by making the first LoadMap
variant not overwrite entries and making the constructor
do everything in the opposite order. An alternative solution
would be to make the second LoadMap variant overwrite entries.
This fixes the global-static fifo object causing infinite hangs in some
cases. Notably, failure to initialize a graphics backend would result in
BlockingLoop::Prepare being called but never executing Run(), leaving the
object in a bad state.
The sanity check runs *before* finalising the import, so at that time
the whole title directory is still in /import and not in /title.
This means we should check for contents there, not in /title. Whoops.
The efficient function (that is nearly the same as
https://graphics.stanford.edu/~seander/bithacks.html#DetermineIfPowerOf2)
replaces one loop based instance (which also reused the xx variable
afterwards, whereas it should have used htabmask instead) and one
instance using the population count a.k.a. Hamming weigth.
This one verifies bitmasks where low bits are set to 1 (hence the name).
Any stray 0 among the lower ones or any stray 1 among the higher zeros
renders the mask invalid.
The edge cases of all zeros and all ones are considered valid masks.
It uses an efficient implementation. It's the counterpart of
https://graphics.stanford.edu/~seander/bithacks.html#DetermineIfPowerOf2
Simpler, and puts the call to CheckIntegrity right where it should be,
instead of being hidden somewhere in a thread class.
This also makes it more obvious what we're getting from the async task.
Oh, and coincidentally, this fixes a random crash that could occur
during the check. I'm not sure why.
This adds a check to ImportTitleDone to make sure all required contents
that are listed in the TMD have been imported before allowing to finish
the import. Not checking for this could allow titles to be left in an
inconsistent state.
There seems to be a race condition between a peripheral device
connecting to the bluetooth controller and it being ready to use.
It's very short and it depends upon the controller, some appear to
connect synchronously and block until the device is ready, others
report the device upon discovery but do not allow communication straight
away. I don't know which is the correct behaviour, or whether it depends
on the peripheral, controller or both. Anyway, Dolphin waits for a
remote to appear and immediately attempts to open the communication
channels, this can fail because the device isn't ready yet, delay, try
again, and it works.
There are other (unlikely) chances the device is busy at random
moments after this initial race condition so it loops around try to
reconnect.
This was inspired by an earlier patch, see here:
https://bugs.dolphin-emu.org/issues/5997#note-20
I can confirm that it works perfectly for me on a bluetooth
controller where otherwise it's impossible to connect (Dell 380
Bluetooth 4.0).
So, a FifoRecorder instance is instantiated as a file-local variable and
used as a singleton (ugh). Most users likely don't regularly use the
FIFO player/FIFO recorder, so this is kind of a substantial waste of
memory.
FifoRecorder's internal RAM and ExRAM vectors are 33554432 and 67108864
bytes respectively, which is around 100.66MB in total.
Just on the game list view on a clean build with nothing loaded, this
knocks debug build memory usage down from ~232.4MB to ~137.5MB, and
release build memory usage down from ~101MB to ~5.7MB.
The GameCube IPL sounds the same when using the free ROM as it does when
using the official ROM (and in Audacity, I couldn't visually distinguish
between the waveforms). It has a reference to an unimplemented function
at 0x8644 which seems to only be used in an inlined version of the CARD
ucode.
This allows the user to go through the Wii Menu first boot setup
screen when they launch the System Menu for the first time.
Most useful on a clean profile, after doing a full system update,
to configure settings like the console country.
