- The defocus pass is now switched off when defocus_x and defocus_y are zero, allowing finer-grained performance tuning.
- Removed YIQ convolution from the main color-convolution shader and replaced it with a full composite encode/decode pass. This is slower, but looks amazing(ly like a terrible TV) and can be turned off.
- More authentic NTSC dot crawl and bandwidth limiting.
- Potential fix for some crashing reported by John IV
- Split color convolution and deconvergence into separate shaders for potential GPU savings down the line
- Added light and heavy variants of the color convolution shader, the former with YIQ colorspace removed
- Re-worked defocus to occur prior to shadow mask application, as it would be on a real monitor.
- Removed Edge Detection, as it was just for fun and can easily be added in by users if desired.
- Split "pincushion" into "Pincushion" and "Screen Curvature", the former affecting the only the displayed image and the latter only affecting the shadow mask.
Part II: Artwork.
aperture.png: Based on Aaron's aperture_4x6 mask but with more prominent notching to bring out the "brick" pattern that was used on many period colour monitors, including the Commodore 1702 - which was, admittedly, not an arcade monitor, but it looks believable and can be changed.
white.png: Default 8x8 255,255,255,255 texture.
Focus: 8-sample blur that averages 7 samples around a center sample.
Phosphor: Not currently used, treated as a pass-through by drawd3d.c, but could be used to implement additional convolutions in a second pass.
Pincushion: Used (when commented in in drawd3d.c) to pincushion an entire full-screen texture but not otherwise apply any convolutions.
Post: The meat and potatoes. It does scanlines, it does aperture masking, it does dot crawl, it does chroma subsampling, it does YIQ colorspace convolution, it does RGB colorspace convolution, it does pincushioning, it walks, it talks, it does the dishes, it'll screw your wife for you, and if you don't have a wife it will find one for you, get you married to her, and screw her for you, IT IS THAT GOOD, LADIES AND GENTLEMEN.
Primary: Simple passthrough for UI and artwork.
Remove the old tokenizing helpers. Add basic classes for ports, fields,
settings, and dip locations as a first step. These will be fully cleaned
up later. Added machine() method to field to hide all the necessary
indirection. Changed custom/changed handlers into generic read/write
handlers, and added wrappers to convert them to device read/write
lines. [Aaron Giles]
MDEC is now an internal device of the PlayStation CPU [smf]
PlayStation DMA uses delegates so devices can be hooked up.
device_t::siblingdevice() uses device list on mconfig() so it can work before the machine is constructed.
moved unused console code back to mess.
Note that msm8251 would be nice to have on emu section but it depends of serial.c which needs to be rewritten in order to be useful. Also upd765 is used only by MESS and it's pain to keep it in emu since it is not yet bug free.
Converted PlayStation DMA to an internal device to the CPU core. DMA to external devices can be set in the machine config, the old calls are still there until the rest of the code is converted. [smf]
The following MAME core changes have been required to allow internal devices to be configurable by the main machine config & to work with internal memory maps.
device.machine_config_additions() are now processed as soon as the device is added, so sub devices can be configured straight away.
replacing or removing a device removes any devices owned by the device being removed, as now they are added straight away.
device_t::subdevice() uses the machine config device list instead of the machine to find the device as the machine is not created until after all the devices have been created.
devices in an internal address map are assumed to be owned by the CPU, while devices in a standard address maps are assumed to be siblings of the CPU.
A code review and regression test would be a good idea.
