base is an unsigned variable, so we can make things little more
consistent by making the loop index unsigned so we aren't doing bit
arithmetic with signed types.
MemoryInterface already does this, so we can leave it alone.
No behavioral changes, just a consistency thing.
This was added in 385d8e2b15, but became somewhat redundant with Do in 4c7bbd96e4, and completely redundant now that std::is_trivially_copyable_v is well-supported.
This adds about a frame of latency, and since most games don't change
VI registers during scanout, we can get away with outputting the XFB at
the start of scanout. WWE Crush Hour is the (only currently known)
exception, which has flickering problems when doing it this way.
This adds a path to perform the output at the end of scanout, and gates
it behind an option which defaults to using the latency-reducing
pre-scanout path.

I must've only tested the frame counter with an earlier version
of the PR that broke this, not the final version...
It used to be the case that frame advance skipped duplicate frames
(i.e. it would take 30 frame advances to get through one second
of emulated time in a 30 fps game), but this broke in 9c5c3c0.
Skipping duplicate frames making TASing less annoying.
This wasn't changed when halfline counts were changed to 0-based. Also
included is a diagram showing an understanding of how the values in the VI
timing registers maps to the video signal.
Datel's Wii Freeloaders set m_PictureConfiguration.WPL to 0 for
a while. Not sure if the fix in this commit is a proper fix or
just a hack, since I'm not very familiar with this code.
With this change, it's possible to run a Wii Freeloader if you
are running an old enough version of the Wii Menu, but the
"coloured bars" that Datel reference in their documentation
never show up. The screen just freezes for a few seconds instead.
- Re-organize VideoInterface::Update() to count half-lines starting at 0 instead of 1
- Use horizontal position when checking if we should assert some display interrupt
- Add some more descriptive comments
With the SI poll line count fixed, pretty much all games are polling
twice per frame anyways, making this option superfluous. Since it's a
bit of a gross hack and makes DTMs incompatible with console, let's
just bin it.
Nowadays that Dolphin detects regions of discs properly and doesn't
force programs with unknown regions (such as homebrew) into running
under a certain region, the "Force Console as NTSC-J" option is
practically useless for making anything run correctly. Enabling it
is however an easy way to totally break many non-Japanese games.
Settings that come from the SYSCONF are now included in Dolphin's
config system as part of the base layer. They are handled in a
special way compared to other settings to make sure they are only
loaded from and saved to the SYSCONF (to avoid different, possibly
contradicting sources of truth).
