SpecEmu v3.4 (build February 14th 2024)

Changes:
  1. Fixed an RZX recording bug. Unlikely to ever trigger it but really don't want to throw recordings away!
  2. Holding ALT when dropping tape images will flip the tape polarity for polarity sensitive loaders.
  3. Fixed a potential issue with loading stripe colours when ROM flash loading is disabled.
  4. Snow effect setting now defaults to enabled on new installs.
  5. Some minor bug fixes.

SpecEmu v3.3 (build June 07th 2023)

Changes:
  1. Added set intdiff n command to set an offset value to add to a machine's interrupt period (0 - 128). This offset is in addition to the late timings setting set in hardware options and the late timings flag saved in SZX (v1.4) snapshots.
