• Resize the sound filter. This should reduce high pitch noise.
• Rework the sleep() code. A new option timerstep has been added to the config file. (See details in there.)
• Some ULA cleanup.
• Some CRTC fixes.
• Added missing formats to the documentation and help strings.

• Renamed some options so they are clearer: --crt renamed to --scanlines, --scanlines renamed to --interlace.
• Added screen rendering modes to CPC: --nodoublescan, --scanlines, --interlace, --average options should work now on CPC models.
• Added palette support.
  • Options --green, --amber, --bw added both to Amstrad CPC and ZX Spectrum.
  • Custom palettes can be loaded now. Any file with extension .pal, containing the colour descriptions in 32-bit RGBA8888 format will be understood, as long as it contains the correct number of colours (16 for ZX Spectrum, 32 for Amstrad CPC).
• Removed unused wz_ register from the Z80 code.

Note that much of these changes were very hastily written, so things may fail.

Improve the sound quality by better adjusting the delay on each frame.

ZX Spectrum 48K late timings implemented so that TimingTest-48K recognises late timings and passes with no errors.
Fixed MEMPTR/WZ value for RET CC instructions.
Improved sample skipping code for accuracy and simplicity.
Rewrote/simplified bus access code for all machines.

Refactor SoundChannel to avoid crashes on MacOS.
Remove --sync for MacOS. This option is unreliable and fails to give a smooth framerate.
Make dark scanlines brighter in --crt mode.

Small fixes.
Moved keyboard update not right before the interrupt. This fixes Blava demo crashing.
Added --crt option which adds darker scanlines (not interlaced)
Documentation strings updated.

PZX format support.
Bugfixes.

Reimplement sound filters to use accumulators.

Fix stuttering sound on MinGW builds.

Added read support for snapshot formats: Z80 and SNA.
