Introduction

This is a stable release (from the master branch).

(the previous stable release was 24th December 2021)

Improvements (Highlights)

  • New NTSC artifact code allows much more accurate emulation of CGA artifact colours which allows the 8088 mph demo to run. Uses code by reenigne, one of the authors of that demo. This code requires a multicore processor and is currently supported on Pi zero 2W, Pi 3, Pi 3+, & Pi 4. Currently not working on Pi zero, Pi 1 and Pi 2 which revert to the old code.
  • Add feature for SW3 to cycle NTSC artifact quadrant phases.
  • Improved support for CGA and Hercules PC cards
  • Fix incorrect Spectrum palettes
  • Fix Apple IIGS 14/16 Mhz auto pixel clock switch
  • Fix grey screen standby not working on c0pperdragon boards
  • Fix erasing of write protected CPLDs (may also require cutting of JP links on underside of board while reprogramming)
  • Various other minor profile tweaks and fixes

Additional Profiles

  • Add 50Hz Intellivision profile
  • Add Harlequin 128K profile (Also Nuvo profile)
  • Add Commodore Pet CRTC profile
  • Add Philips Videopac C52 profile
  • Add Amstrad CPC+ profile
  • Add TRS80 model IV profile
  • Add EGA Wonder 800+ profile
  • Add Spectrum 48K c0pperdragon RGB interface profile (bright colours work)
  • Add Spectrum 128 and +2(grey) profile on analog interface (previously only digital interface)
  • Add proposed commodore 64 lumacode profile for future c0pperdragon board.
  • Add support for PETSCII Robots custom mode on 60Hz C128
