[ATARI] Altirra x86 i x64 3.20 test X

Nowa wersja testowej Altirry, emulatora ATARI XE/XL/5200. Altirra została wzbogacona o modyfikację wyświetlanego obrazu - czyli psujemy krystaliczny obraz LCD, tak aby wyglądał on tak, jak 30 lat temu na naszych telewizorach;)

Ostatnia pełna wersja tego emulatora, jaka publicznie została udostępniona to Alirra 3.10 z 12 sierpnia 2018 r.

Super Huey (1984, Cosmi). Najbardziej zabezpieczony program na Atari - bez oryginalnej instrukcji wystartowanie graniczyło z cudem. Ten, który zakupił na giełdzie grę z ksero był mistrzem;)

  • Display: Added option to acceleration some screen effects using shaders when Direct3D 11 is enabled.

  • Debugger: Mini-assembler no longer emits ROR opcodes as LSR.
     

Author's Comment:

Initial support for hardware accelerated screen effects:

Test Screen (new screen filter).

 

This is an early version, so there are still some bugs, but these are the changes:

  • Gamma/color correction can now be accelerated on the GPU. For plain displays, this was done for free through the palette, but any effect that forced 32-bit rendering incurred extra cost for this. In particular, color correction about doubled the CPU cost of NTSC artifacting, which this brings back down. The main intention is to make it reasonably cheap to switch color correction on in the default NTSC color profile for more accurate default colors.
  • Scanlines are also accelerated on the GPU and rendered with better quality: full resolution instead of double vertical interpolated and computed in linear space instead of gamma space. This reduces moiré effects. GPU scanlines can also be rendered in interlace mode, though you need at least an FHD resolution display to do so (>960 pixels vertical).
  • PAL artifacting (chroma blending) can now be GPU accelerated. (NTSC and PAL high artifacting still cannot.)
  • Barrel distortion and bloom/glow simulation is now supported. These are tuned through a new dialog in View > Adjust screen effects.

Caveats:

  • Screen effects currently require DirectX 11 and a shader-capable graphics card (DX9-class or above). DX11 must be enabled in Options > Display and thus this won't work on Windows XP. I should be able to reimplement these for DX9 (needed for Windows 7 as well as XP) but don't want to maintain two code paths just yet.
  • GPU acceleration of existing effects requires checking an enable in Configure System > Emulator > Display. Barrel distortion and bloom don't, those require GPU acceleration to work. Some features like video recording will disable accelerated effects.
  • Screen position dependent features like text selection, light gun, etc. are not currently barrel distortion aware and will ignore it.
  • There are some known issues with artifacts along borders.
  • Most of the effects should be pretty cheap on any graphics card that can run them, but the bloom in particular may cause slowdowns if you have a very weak graphics card. The slowest DX11-capable GPU I have is an Intel Graphics 520 (Gen9/Skylake), which gets up to around 40% when rendering all effects at 2560x1440.

I would like to get NTSC high artifacting accelerated so the full NTSC display pipeline can run on the GPU, but the algorithm is a pain to convert. It'd either be a very heavy pixel shader or a very ugly compute shader and it may require a higher GPU spec than the rest of the effects.

Also, a couple of miscellaneous fixes:

  • Fixed a case where auto NTSC/PAL high artifacting wasn't the same as selecting the specific mode: the sharp bilinear filter wasn't adjusted the same way.
  • Fixed ROR instructions assembling as LSR in the debugger's miniassembler.

Author's Comment:

  • Rewrote hook for loading BASIC tapes. It now uses CIO hooking for injecting the CLOAD and RUN commands like the BASIC program loader does, for better speed and reliability.
  • Fixed a bug in the ROM validator for WarpOS 32-in-1. Haven't seen failures of this in the wild.

  • Cartridge: Manually inserted BASIC cartridges are now persisted across runs of the emulator.
  • Cassette: References to tapes mounted directly as .zip files without a direct reference to a file within the zip are now persisted properly across runs.

Author's Comment:

  • Fixed regression in ANTIC display text selection.
  • Manually attached BASIC cartridges (File > Attach Special Cartridge > BASIC) now restore correctly on next run.
  • Added option to detect whether a tape starts with a BASIC program. If so and this option is enabled, the emulator bypasses holding the Start button, enables BASIC, and types CLOAD.

  • ATBasic 1.56: Fix for crash that occurred when hitting Break prior to startup banner.
  • Fixed Input State and Console controller types not activating in input maps in 5200 mode.
  • Added copy/paste escaping support: special keys like Invert and arrow keys can now be pasted with escape syntax in braces, i.e. {invert} and {left}. There is now also a copy escaped command that will use these escapes to produce keystrokes that can re-type those characters. ^ and + prefixes mean control and shift, i.e. {^tab} and {+tab}.
