- merged YIQ encode and decode pass into one NTSC pass
- added options for most NTSC settings
- reduced sample count to 64
- changed default O value to 0
- fit NTSC signal jitter between a reasonable limit of 0 and 1
- fit A and B value between a reasonable limit of -1 and 1
- fit scanline jitter between a reasonable limit of 0 and 1
- added hum bar simulation based on [MooglyGuy's] GLSL port of the mame
shader pipeline
- added monochrome-chessboard.png
- added slot-mask-aligned.png (to simulate a TFT LCD)
- replaced shader parameters OrientationSwapXY xor RotationSwapXY by
SwapXY
- made shader parameters SourceDims, SourceRect, TargetDims, ScreenDims,
QuadDims and SwapXY available for all shaders
- color convolution, defocus and phosphor pass will now be skipped if
all influencing parameters are 0
- removed unused bloom_texture and bloom_target arrays from cache_target
class
- fixed half texel offset in prescale.fx
- added shadow mask type option to choose between "Screen" and "Source"
tile mode ("Screen" is the default as before)

color of the screen by the amount of the inverted alpha value
- added monochrome-matrix.png which can be used in combination with
"Source" tile mode and "Darken" blend mode to simulate a STN LCD, for
example
- fixed wrong detection of vector screen, which meant that a LCD screen
was also detected as vector screen
- re-enabled scan-line and other CRT related sliders for LCD screens
- screen adjustment (scale, offset) can now be handled by the respective
render API itself (default behavior is as before)
- D3D (if HLSL) is activated handles screen adjustment by itself within
the shader, which fixes the odd behavior of some effects (e.g. round
corners) when screen scale and offset is used
- added special post.fx and distortion.fx shader, which support enabled
artworks, but they cannot apply some of the previously implemented
corrections (e.g. bloom staircase artifacts when screen is curved,
elliptic rounded corners when aspect ratio is not 4:3)
- added distortion pass, which is applied after the bloom pass
- moved vignetting, curvature, round corners and reflection effect to
distortion pass
- disabled distortion pass for multi screens and activated artworks due
to not yet fixed misalignments
- disabled scanlines for vector rendering in post pass shader
- removed prescale knowledge from downsample, bloom and post pass shader
- fixed half pixel offset in most shaders
- fixed position of reflection effect when screen is rotated or flipped
- fixed roundness of round corners in any aspect ratio
- fixed shadow mask bleeding (nearly completly)
- added bounds() and screen_bounds() getter to layout_view
- added current_view() getter to render_target
- some cleanup and refactoring
- removed position offset in post.fx
- fixed texture offset caused by 0th level of bloom.fx
- fixed texture offset caused by focus.fx
- changed Passthrough parameter in phosphor.fx to boolean
- simplified defocus pass function and calling it twice
- removed CU_PHOSPHOR_IGNORE (Passthrough) uniform, which was only used
in phosphor pass function and is now directly set
- added CU_TARGET_DIMS (TargetDims) uniform based on the current render
target
- fixed missing Prescal parameter in downsample pass function
- some code cleanup
- added support for post pass effects for vector rendering (does not
work properly in full screen mode, yet)
- made texture_info::compute_size_subroutine() function public static
- fixed roundness of rounded corners; the default aspect ratio of 4:3
should not be stretched anymore when the source has another ratio
- disabled blurring of rounded corners
- some cleanup
- changed shadow mask implementation, shadow count XY now represent the
number of pixel the shadow UV sized tiles will take on the screen
- implemented rotation of the shadow mask texture depending on the
default landscape or portrait view of the screen
- removed prescale and pixel border of the shadow mask texture
- added option to change the shadow UV offset, to reduce the color
bleeding of the shadow mask
- adjusted presets to work with the changed mask implementation
- reduced defocus offset
- improved downsampling for better blurring
- improved alignment of bloom layers (raster and vector)
- applied bloom effect to the render output of screenshot and AVI
recording
- changed curvature effect to fit screen size
- changed scanlines to be not rendered into bloom layers
- changed shadow mask to be not rendered into bloom layers
- changed color floor to not light the bloom layers
- changed shadow mask to not dark the color floor
- added image vignetting simulation and option
- added round screen corner simulation and option
- added screen light reflection simulation and option
- made usage of unused brightness offset (additive)
- removed unused pincushion option
- removed duplicate shadow count Y options
- removed artwork/adapture.png
- added artwork/adapture-grill.png
- added artwork/shadow-mask.png
- added artwork/slot-mask.png
- added hlsl/simple.fx
- removed unused shaders::blit() function
- added shaders::screen_pass() function, which handles the
(raster-)rendering on screen, into screenshot and AVI recording
- added effect:set_bool() function
- HLSL changes: [MooglyGuy]
* Upped vertex buffer size to 64k verts, fixes assert in
starwars and alphaone, please include the printed error
message in any subsequent encounterings of the assert.
* Improved vector rendering (beam width 1.5 suggested)
* Ducked raster bloom default to 0.225 to reduce washout
openly, for there was nothing left to see with" [MooglyGuy]
* Enabled vector bloom and associated .ini controls
* Added raster bloom and associated .ini controls, each bloom "level" is the
linear weight of successively half-sized render targets
* Removed D3D8 mode
* Mass renaming in D3D renderer to use namespaces, initial planning step to
HAL-based renderer implementation on Windows (i.e., GL on Windows)
* Converted d3d_info, d3d_poly_info, and d3d_texture_info into classes
* Added batching of vectors for possible speed increase
* Minor cleanup of shader state setting
- Fixed set_vector functionality and simplified shaders as a result
- Fixed HLSL presets, 0 to 3, in increasing level of terribleness
- Reduced options footprint from RGB triplets
Next plan: Separate INI writing.
- Reworked default shadow mask settings, eliminating rainbow banding and matching reference shots more closely
- Moved color power to occur after shadow mask, as it is intended to simulate nonlinear phosphor response
- Added a variable-width notch filter to the Y channel in NTSC post-processing, eliminating luma banding on e.g. CoCo 2 and Apple II
Attempting to fix the HLSL 'blurriness' reported by a few people. Now HLSL will auto-prescale to the nearest texture size that is greater than the target screen size on both axes and is also an even multiple of the raw bitmap's size.
- Added the ability to render screenshots at arbitrary resolutions.
- Added the ability to record AVI videos (albeit with no audio) at arbitrary resolutions.
- Added a 43-tap-wide FIR-based NTSC filter with tunable Y, I and Q frequency response.
- Updated scanlines to have a user-tunable pixel-height ratio in addition to the current screen-height ratio.
- Fixed a VRAM leak that was causing many dynamic-resolution drivers to run out of memory mid-run.
- Switched to point-sampling through most of the shader chain to avoid non-intentional pixel smearing
- Corrected alignment and scaling on the shadow mask and scanlines; dramatically reduces rainbow banding at non-oversampled resolutions.
