#477
## Description of change
By default the game needs 4 monitors.
With the new option to disable subscreens, you can now boot fullscreen
with a single 4K monitor, with subscreen overlay enabled. Side monitors
are not shown in the overlay; only the touch screen is emulated.
## Future work
- [ ] custom resolution (-forceres) doesn't work properly (hooking
ResetEx does allow the game to boot but will render incorrectly;
probably needs hex edits)
- [x] enable this automatically if the user has fewer than 4 monitors
- [ ] ability to boot with a 4k main screen + small subscreen (with no
side screens which do nothing gameplay wise), but this whole display
emulation is a nightmare to work with & test thoroughly so it'll have to
be in the future.
## Testing
Checklist:
- [x] fs on 1 monitor with option set
- [x] fs on 2 monitor with option set
- [x] windowed - default (4 windows, no overlay)
- [x] windowed - with option set (1 window, overlay)
- [x] fs with 4 monitors?
- [x] check popn hc for regression

## Description of change
Take the monitor hooks added for IIDX/SDVX #612 and apply it to popn as
well now that popn has a subscreen.
There is a debug option in game that actually uses three monitors, which
can be activated via hex edits. This will prevent that from working.
## Testing
Tested with 3 monitors, fs and windowed.

## Description of change
The game insists on having two monitors. Hook various DX9 and Win32
monitor APIs to fake a monitor if the user only has one. This correctly
convinces the game that it needs to draw two screens instead of just
one.
## Testing
WIP

## Description of change
Add overlay for subscreen.
Add an option for no subscreen window.
Use the same "force redraw subscreen" logic we used in SDVX to fix the
same issue.
Known issues:
* still crashing when running windowed if there is only one monitor
* having only one monitor causes sunscreen overlay to not work
(NumberOfAdaptersInGroup issue?)

## Description of change
Turns out running this with bi2x doesn't process buttons properly, so we
have to use bi3a.
## Testing
Seems playable now.

#618
## Description of change
The game expects the main display to be *not* HDMI, and at port 2.
Hooking DisplayConfigGetDeviceInfo allows us to boot the game on any
monitor.
Add basic I/O hook. It gets stuck in `USB I/O Checking...` for a couple
minutes but it'll eventually skip and boot to title screen.
## Testing
ugh.
