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).
VideoInterface::Preset was not initializing all registers, this is a problem
because it leaks register settings across games. Xenoblade Chronicles does
not like m_DisplayControlRegister having random bit patterns in it.
The NES games on the Zelda Collecters Edition disk use a XFB which is
only 256 pixels wide, but has a stide of 640 pixels.
This fits our definition of a interlaced xfb, as a second line of data
could fit in the extra space. The solution is to check that we are
actually in a interlaced video mode before activating the force
progressive hack.
They are now based on signal timings rather than pixels, as it
didn't make a lot of sense to do things with pixels.
Now handles all 240i/240p/480i/480p modes without any special
casing.
Despite the diffrent equaions, this should result in the exact same aspect
ratio as the previous code.
The "Force NTSC-J" option was broken by 480dbb22f2
(i.e. field-timing). A side effect of this was that it exposed a bug
where the JP region bit of VI's DTV reg was not automatically set for wads
from the JP region.
Gets rid of magic numbers in cases where the array size is known at compile time.
This is also useful for future entries that are stack allocated arrays as these
functions prevent incorrect sizes being provided.
Based on advice from tueidj we implement this method based on how
TVs actually determin the field order.
Removes spammy messages about "Invalid field order"
