- HLSL now uses NPOT sized target surfaces (breaks compatibility with
graphics cards based on R300/R400/NV30 and older)
- HLSL target surfaces now have the size of the screen canvas
- removed HLSL pre-scale factor
- HLSL now uses a sharp bilinear interpolation to pre-scale textures to
screen canvas size, based on [Themaister's] implementation
- improved overall performance (based on the previously required
pre-scale factor, you might notice a 5-50% speed-up depending on your
graphics card, more if you used a higher pre-scale factor)
- improved shadow mask quality (pixel-perfect) in screen-mode
- fixed half source texel offset of bloom level alignment
- removed ./hlsl/artwork_support folder
- all shaders after pre-scale are now based on screen coordinate
(workaground, till both raster and vector pass can work on texture
coordinates)
- disabled distortion shader for more than one screen and for artworks
in full mode, does not affect artworks in copped mode (workaground, till
both raster and vector pass can work on texture coordinates)
- moved compute_texture_size() from texture_info to texture_manager (nw)
- fixed target dimensions of bloom levels, which results in a much
better alignment especially for game with very low resolution (therefore
current bloom settings might look a little less intense than before)
- small cleanups (nw)
- changed the amount of scanline darkness, a setting of 1.0 now becomes
fully black (to get the same result as before half your current setting)
- scanline height now depends on the brightness of the underlying color
- the amount of the scanline brightness and overdrive now depends on the
scanline darkness
- renamed 'Scanline Screen Height' to 'Scanline Screen Scale' and
'Scanline Indiv. Height' to 'Scanline Height'
- 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)
(MESS) CPUID.ASM (Bob Smith 1985) suggests that in situations where
m_no_interrupt is 1, (directly after POP SS / MOV_SREG), single step
IRQs don't fire. [Karl-Ludwig Deisenhofer]
(although not knowing much about the intv I'm a bit confused by this patch, it looks almost like it's adding fake controller support, which doesn't seem desirable?)
