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.
Fixes a critical regression where 95945a0 made us unable to
start emulation on Android 10 and newer. Android is restricting
direct access to /dev/ashmem starting with the new SDK version,
but we can use the new (and simpler) ASharedMemory API instead.
We have to keep using the /dev/ashmem approach on old versions
of Android, though.
This modifies GCMemcard::TitlePresent() to match my findings of how the GC BIOS and various games behave when you alter the fields in the directory entry.
It looks like for a save to be recognized by a game, the following have to be true:
- Game code and maker code must exactly match what the game expects.
- Filename is only checked up to the first null byte. All bytes afterwards can be whatever.
The BIOS itself does a full compare of the filename when checking for whether it should allow copying a file from one card to another, but behaves oddly in some cases when there's non-null bytes after the first null. See the big comment in `HasSameIdentity()` for details.
This could cause read errors if chunks were laid out a certain
way in the file and the whole chunk wasn't being read at once.
Should fix https://bugs.dolphin-emu.org/issues/12184.
I believe the value returned by value() resets when we call
setValue() with the maximum (due to auto-reset). I have been
unable to test this because I can't reproduce the issue, which is
described at https://bugs.dolphin-emu.org/issues/12158#note-9.
The functions with "UTF" in the name use "modified UTF-8" rather
than the standard UTF-8 which Dolphin uses, at least according
to Oracle's documentation, so it is incorrect for us to use them.
This change fixes the problem by converting between UTF-8 and
UTF-16 manually instead of letting JNI do it for us.
This function does *not* always convert from UTF-16. It converts
from UTF-16 on Windows and UTF-32 on other operating systems.
Also renaming UTF8ToUTF16 for consistency, even though it
technically doesn't have the same problem since it only was
implemented on Windows.
