Fixes#833
## Description of change
Last couple PRs - such as #820#827#828 - made the native touch hook &
touch injection using `InjectTouchInput` the default path, since it
performs much more reliably with both real touch screens and mouse (or
any other synthetic source).
However, user has reported that WINE lacks `InjectTouchInput` which
means this won't work.
As a fix, revive the old wintouchemu code. Native touch is still the
default, but under following circumstances:
1. if `-touchemuforce` is set, or
2. if any of the required Windows touch APIs are unavailable
then we fail over from native touch to wintouchemu code.
For Linux, condition #2 would be hit during init, and gracefully switch
over.
Caveat: the poke code for IIDX and Nost will continue to require native
touch, I do not want to maintain two paths for this. This means that
iidx poke will stop working on Linux, unfortunately.
## Testing
Tested on Windows with `-touchemuforce` set. This is mostly reverting
Linux code path back to where we were last release, so this should just
work with wine.

Touch piano mode. Allows piano keys to be played with the touch screen.
Since the touch screen is still needed for menu navigation (including
during songs) a toggle switch is added so that the user can flip between
navigation mode and piano mode.
The touch targets are pixel-perfect. Don't let the game's piano
animations fool you.

## Description of change
Remove iidx/sdvx/popon `native touch` options.
Remove dead code in wintouchemu that deals with these games.
Native touch is now at feature-parity with wintouchemu. Native touch
options work better with touch screens, while rawinput-based wintouchemu
has compat issues on some touchscreens. For these subscreen games
deprecate the usage of wintouchemu and make them use native touch stack
by default.
### For future consideration
Gitadora - not sure what to do with this one. We only use wintouchemu
for the single window case. For all other configurations, the game
accepts mouse and touch input without any hooks, so perhaps nothing
needs to be done here.
Nostalgia - consider moving away from wintouchemu and adopt native touch
hook here as well.

## Description of change
Sometimes the game moved the main window after `CreateWindowExA`
returned but before D3D initialization called
`graphics_capture_initial_window`. During this gap,
`GRAPHICS_HOOKED_WINDOW` was not set, so the placement hooks could not
identify the main window and preserve its monitor override. GITADORA
main, LEFT, and RIGHT windows are now registered immediately after
creation so later placement calls cannot undo their overrides.
This also adds `-gdwsmallsize` and `-gdwsmallpos` for explicitly setting
the SMALL window size and position. Explicit values override the
corresponding monitor-derived geometry, allowing the SMALL window's
10:16 aspect ratio to be preserved instead of stretching it to fill a
monitor.

Add a new option that paints touch targets and touch points for jubeat;

Also, simplify the `improved` algorithm to simulate a finger and trigger
nearest-neighbor for the AC dimensions. In terms of touch performance
this is near identical to what we had before, but it allows us to draw a

Fixes#697
## Description of change
Adds aspect-ratio compensation for raw input touch handler.
This addresses the problem with playing rawinput touch games - namely
jubeat and reflec beat - on a display that is not 16:9, and user chose
to preserve the aspect ratio. This happens a lot on:
* 16:10 touch screens
* touch screen laptops (which range from 3:2, 16:10, and so on).
Root cause is a **Windows Raw Input limitation**. Unlike
`WM_POINTER`/`WM_TOUCH`, where the OS already maps digitizer coordinates
to screen space (applying the display's calibration/scaling), Raw Input
delivers the HID digitizer's *raw* logical coordinates, spanning the
whole physical panel, with **no calibration or display-mapping data
attached**. We have to reconstruct that mapping ourselves.
When a game runs at a display mode whose aspect ratio differs from the
panel's native resolution, Windows scales the image with
letterboxing/pillarboxing (black bars). That is standard OS/GPU
behavior. Because Raw Input gives us no mapping to account for those
bars, touches land off-target. This change detects the mismatch and
remaps each touch from panel-space into the displayed image region;
touches inside the black bars are treated as released.
Adds new launcher option **`-rawtouchaspect`**.
Notes:
- Native resolution is the largest-area mode from `EnumDisplaySettings`
on the **primary** display, consistent with the existing primary-only
touch pipeline.
- Math assumes centered, aspect-preserving scaling; only one axis is
ever inset.
- A small epsilon (0.01) makes near-matched panels (e.g. 1366×768 vs
true 16:9) a no-op.
- If the user forces a stretched image, then the touches will be off
again. In this case, the user needs to use the `force off` setting.

* checked that jubeat squares align correctly

## Description of change
This new option, `-wasapishared`, detects when the game opens WASAPI
Exclusive stream and forcibly opens a shared mode stream instead on the
real device.
#### Benefits of this:
1. No need for `force wasapi shared` patches
2. No need to change sample rate of audio devices before starting up
games
3. Adds ability to boot in shared mode even for games that do not have
shared wasapi changes (old GITADORA, popn HC)
As a result, this option is strictly better than `shared wasapi` patches
available for many games.
#### Downsides:
1. OS resampling will add a small latency, but not big enough to be
noticeable.
2. Using shared mode instead of exclusive mode adds latency, of course.
(If you cared about latency, you would use the low latency option, or
use exclusive or asio)
Basically it's the "make things work" button for audio that should work
for almost all games that we support.
The option has no effect if the game opens in shared mode.

## Description of change
Create three distinct layers for the overlay:
1. Bottommost persistent layer - non-interactable layer that is always
on. This was only for notifications, but now the FPS widget lives here
as well.
2. Overlay windows layer - most interactable windows go here.
3. Topmost main menu - this is reserved for the main menu (escape key)
and this is a modal dialog that occludes the layers below.
Why?
- `toggle overlay` behavior with FPS widget *also* toggling on/off was a
bit confusing (now they're two separate keys)
- FPS widget is popular, but it caused the entire overlay to be active,
which affects how input is handled
- the main menu being a standalone window was a little awkward (now it's
a modal)

Create `WrappedAsio`, similar to how we wrap `IAudioEndpoint`
So far, the wrapper does these things:
1. logging (for diagnosis, since iidx and gfdm don't produce any logs
when asio succeeds)
2. iidx32+ hack to work around refcount mismatch issue
3. sdvx valk cab hack to force 2-channel audio ("downmixing" by taking
only the front channels)
4. honor volume boost
As a result of `#2` the mempatch was removed from `iidx.cpp` since we
can tackle it cleanly in the hook. `#3` also removes the need for manual
patches.
Real downmixing is hard & expensive on the CPU so it was not
implemented.

## Description of change
Resampler:
Implement resampler for exclusive mode streams, as we are seeing more
and more devices - not just laptops but onboard audio devices - that
only support 48khz and not 44.1khz. Should work with volume boost (gain
calculated inside resample) and also downmixer (hands off intermediate
scratch buffers).
Buffer size increase:
By default many of these games request a tiny buffer when in shared mode
(TDJ uses 3ms). On some audio setup this results in crackling due to
underflow. Add an option to forcibly increase the buffer size.
## Testing
With resampler set to 48kHz and buffer set to 20ms I can reliably boot
and play IIDX on my display port monitor's speakers; previously this
wasn't possible. IIDX is event-driven.
Tested SDVX7 as well at 48kHz, which opens timer-driven streams.

Fixes#717, fixes#647
## Description of change
Adds an option to downmix surround sound (5.1, 7.1, etc) down to stereo
(2 speakers). This can be used in most WASAPI games, including Gitadora
and FTT.
How it works: when the game tries to open surround format (say, 7.1) we
create a fake buffer and tell the game that it is supported. In reality
we open a 2-channel stream with the real sound card. When the stream
begins, we downmix the channels down to two (using one of many
algorithms) and output to the sound card.
While we're here, implement an option to boost the game volume by some
decibel value, which is a feature often requested by SDVX players. This
was needed since downmixing can sometimes result in quieter audio.
## Testing
Tested GW Delta and FTT.
Downmix doesn't work on IIDX (32 bits) but volume boost works.

## Description of change
Adds a way to automatically use the PIN Macro for P1, P2 or both when
Auto Card Insert is used.
### Launcher changes:
- Added a checkbox to enable/disable the feature
- Added a textbox for each player to set what to look for in the logs.
### How it works:
The feature requires Auto Card Insert and PIN Macro to be enabled and
set.
It uses the Auto Card Insert value to enable the feature for P1, P2 or
both, with a "master" checkbox to completely disable the feature. It
then relies on the current PIN Macro code to send the PIN to the games.
The games logs send a message when a new scene is loaded with the name
of the scene. By hooking on the logs, we can see when a PIN is required
and send the relevant macro. Games have different scene names, and
sometimes one for each player, so the field is configurable per game per
player. These could be hard-coded in a lookup table but I didn't want to
recompile the project every time I wanted to test, and I don't have all
the games to get this info from.
The PIN Macro thread is used to hook to the logs and check if the
defined string appears, which triggers the PIN macro just like a button
press would.
Setting nothing for the log trigger disables the feature for that
player. It's useful if someone wants to have Auto Card Insert enabled
for both players but only Auto Pin on 1 player, but is mainly there so
the check won't happen if nothing is set.
## Testing
I used SDVX and DDR to have a single and a two player test with the
feature both enabled and disabled. I also tested multiple combinations
of PIN Macro settings and Auto Card Insert settings with no apparent
issues. The PIN is automatically entered as soon as the game requests
it.
## Discussion
I know that hooking to the logs might not be the best solution. I'm very
open to discussions about this, and understand that this might be a deal
breaker for this feature. I made this to use with my setup and thought
I'd try opening this PR to see if the feature would be useful for
others.
I haven't found another way to make sure we're on the correct screen to
launch the PIN Macro, and sending the macro every time the Auto Card
Insert finishes had sync issues where the end of the PIN would actually
be registered by the game.
It would also be much more convenient for the users to hardcode a lookup
table for every games' log-trigger but I don't have the games currently
so I can't check the logs to see what would be best.

#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] fs with 4 monitors?

#694
## Description of change
Before this change, we have it set in the executable manifest to always
ask for UAC elevation.
This change removes that and instead attempts to prompt for elevation
when we launch, depending on the new developer option that is being
added here to run as current user instead of elevating.
The default behavior continues to run as admin. This is still the safest
in terms of regression risk.
A bit of history on this: while spicecfg never technically needed to
elevate, we continue to do so to avoid difference in behavior when the
game is launched. For example, if the user is using an input remapper
running without elevation, it would inject input into spicecfg running
as user but fail to do so if the game runs elevated.
WinXP builds are unaffected (there is no UAC).
Some features will straight up fail without elevation so this will
remain as a debug option. To name a few (not a complete list):
* reboot/shutdown of PC
* running at realtime process priority
* `-nvprofile` option
* ...

Fixes#681
## Description of change
`Sleep` and `sleep_for()` can be very inaccurate and varies depending on
what the OS gives us...
### `timeBeginPeriod(1)`
On boot, we are now calling `timeBeginPeriod(1)`, which affects the
whole process but makes `Sleep` more accurate. There is some risk here
if any game was relying on doing things like `Sleep(1)` and expecting it
to run for 15.6ms. Most games already call `timeBeginPeriod(1)` in the
game engine, though not the whole time, so I'm hoping that this is not
too impactful.
### Opt out of Win11 power throttling
Ensure that timer resolution change above is respected even when the
window is occluded / minimized by opting out of throttling via
`PROCESS_POWER_THROTTLING_IGNORE_TIMER_RESOLUTION`.
### Use Win10 high resolution timer instead of Sleep
On Win10 1803 and above, there is a new OS-level API for high resolution
timers; if this is available, use it
(`CREATE_WAITABLE_TIMER_HIGH_RESOLUTION`). Worth noting that WINE
doesn't support this currently.
If not, fall back to `Sleep`, which is significantly better than
`sleep_for()` in my experiments.
Callers of Sleep / sleep_for were replaced with this new timer. Most of
them anyway; calls to Sleep() with more than 100ms+ was left alone.
### Add an option as a chicken bit
To opt out I'm adding a new option called `Use Legacy Timers` which will
revert to behavior before this PR. The code paths that switched from
`sleep_for` to `Sleep` will remain in place though, not affected by the
option.
## Expected changes
In some I/O emulation modules, poll threads may run more frequently,
resulting in lower latency.
It also means that spice overall may use more CPU resources and power.
If you don't like this, you can always enable the option to opt out;
e.g., if you're on old arcade cab PC.

## Description of change
Adds a flat-C, headers-only library for writing DLL plugins with spice.
This is meant to be an alternative to writing applications over spice
API which doesn't suit some scenarios like writing custom
high-performance I/O modules.
All you have to do is:
1. Create a 32-bit or 64-bit DLL with `spice_sdk_entry_point` as a
DLLExport
1. Include `spicesdk.h`, and optionally `spicesdk_io.h` (see
`extras\sdk\include`)
1. `spice_sdk_entry_point` will be called when hooks get initialized.
Call `init` with valid parameters.
1. When `init` returns, `SPICE_SDK_V0` will be filled out with a series
of function pointers; your DLL can now start calling into it.
1. Compile your DLL and add it as a DLL hook (`-k`) in spice when
launching the game.
See `v0_cpp.cpp` for an example.
V0 implements the following functions:
```
log;
get_game_info;
get_avs_info;
get_button;
set_button;
get_analog;
set_analog;
get_light;
set_light;
set_touch;
clear_touch;
insert_card;
set_keypad;
```
V0 is focused on providing common utility functions needed in a lot of
DLL hooks (get AVS info, log messages to file), and implementing I/O.
In the future, we could have more interesting things like:
* scanning and modifying memory
* installing DLL hooks
* having direct hooks into I/O emulation modules
* getting full tape LEDs
* having a callback into DX9 `Present` call
* drawing an ImGui window
More detailed documentation is coming soon in form of a wiki page.
