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.
Fix up the calculation of the length fields and check that the returned
response is the expected length. This touches many files because it
converts a parameter name from the SI_Device interface from 'length' to
'request_length'. Prior, this field seemed to be used as request length
sometimes, as response length sometimes, and usually just totally ignored.
Different address spaces can be chosen in the memory view panel.
* Effective (or virtual): Probably the view people mostly want. Address
translation goes through MMU.
* Auxiliary: ARAM address space. Does not display anything in Wii mode.
* Physical: Physical address space. Only supports mem1 and mem2 (wii
mode) so far.
Dolphin has traditionally treated the SI IO buffer (128 bytes) as a set of
32 little endian u32s. This works out fine if you only ever read/write
using aligned 32bit accesses. Different sized accesses or misaligned reads
will mess it up. Byte swapping reads/writes will fix this up, but all the
SI devices that use the SI IO buffer need to be adjusted.
This option completely disabled the DCBZ instruction. Users are toggling
this option in dolphin forks and using that same problematic config when
launching dolphin. Removing the option from dolphin will let the config be
ignored.
Paired single (ps) instructions can call asm_routines that try to update
PowerPC::ppcState.pc. At the time the asm_routine is built, emulation has
not started and the PC is invalid (0). If the ps instruction causes an
exception (e.g. DSI), SRR0 gets clobbered with the invalid PC.
This change makes the relevant ps instructions store PC before calling out
to asm_routines, and prevents the asm_routine from trying to store PC
itself.
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.
Baten Kaitos allocates its XFBs from a tagged heap
structure. With the old calculation, too many lines
were being written so the tag of the allocation
after the XFB was being corrupted. Fixes crash

When calculating the size of the undisplayed margin in the case where
fbWidth != fbStride for RealXFB for displaying in the output window,
we do not scale by IR - RealXFB is implicitly 1x.
When AIDMA begins, the first thing it does is load the source address
and length into internal registers. It then triggers the AID interrupt.
Some begin the AIDMA process without all the data necessary for the
interrupt callback being set up already - they require a few more cycles
to set it up (the delay between the DMA being set to begin and the
interrupt firing). The value of this delay was approximated by tests on real
hardware.
