changes

  • Debugging symbols and debugger scripts are now only automatically loaded when the debugger is active.

features added

  • Debugger: #comments can now be used in .atdbg files.
  • Debugger: @(...) within an expression causes that subexpression to be evaluated immediately.
  • Debugger: .diskdumpsec now dumps phantom sectors for a virtual sector.
  • Disk: Added support for physical sector size chunk in ATX images.
  • Display: Added new overscan mode for typical widescreen displays.
  • Display: Added controls for scanline intensity and scaling overall display intensity.
  • Display: Optimized standard NTSC artifacting algorithm.

bugs fixed

  • Disk: Improved emulation of FDC not ready bit ($80).

Author's Comment:

  • Breaking change: Debugger scripts (*.atdbg) are no longer automatically loaded for images unless the debugger is enabled (/debug or via menu).
  • /portabletemp runs off an INI file but doesn't save any changes back to it, for testing.
  • Added support for ATX physical sector size tagging.
  • Fixed disk Not Ready status bit updating inconsistently in some cases.
  • Rotational delays are skipped for disk drives that have a ready signal -- 1050 emulated modes no longer have long delays reading from uninserted disks.
  • Fixed Not Ready being signaled for drives that don't support it (810).
  • Optimizations to ANTIC emulation and NTSC standard artifacting.
  • @(...) in debugger expressions evaluates the subexpression immediately. Example: bx pc=@(pc+100)
  • The .diskdumpsec debugger command now shows all physical sectors associated with the given virtual (logical) sector.
  • Added 'widescreen' overscan mode for the horizontal area commonly shown by modern widescreen LCDs. The visible area is 176 color clocks.
  • Added setting for scanline intensity.
  • Added intensity scale setting.

The intensity scale setting allows the entire display image to be easily scaled up or down without adjusting the rest of the controls. This could be done previously but required moving several controls in sync. The reason for this is to make it easier to darken the image produced by the emulator and turn up the physical monitor brightness for better color reproduction. This is especially useful when trying to match the colors from an 800, which naturally produces a dimmer and highly saturated image. Without this adjustment, the colors are warped due to hitting the limits of RGB space:

Turn the image down to 66%, and the purple turns to blue:

changes

  • nw

features added

  • UI: Added a GUI option in settings for switching between portable and registry mode.

bugs fixed

  • Disk: Full disk emulators now report address CRC errors properly ($E7).
  • Disk: Improved accuracy of disk errors from XF551 full drive emulation.

Author's Comment:

  • There is now a command in Options to switch between Registry and portable mode for settings. Portable mode has been supported for a while, but this automatically moves the settings over as well.
  • Address CRC errors are now reported correctly for full disk drive emulators, and fixed error reporting issues specific to XF551 full emulation.
