NextDAAD Authoring Kit v0.5.0

0.5.0 - 12 August 2026

New

• The 80 column text display can now use the full Spectrum Next palette
• INK n, PAPER n and BORDER n now take any value from 0 to 255,
  not just 0 to 15. 0 to 15 are the classic Spectrum colours, unchanged;
  16 to 255 are the standard Next colour of that number, the same
  RRRGGGBB convention used for Layer 2 artwork. See
  customising.md for the arithmetic and worked examples.
• PAPER 8-15 now renders bright rather than folding to the dim hue,
  matching the Spectrum's own BRIGHT semantics more closely. A game
  that used those values expecting the old dim fold will look different.

Fix

• A GAME.DDB compiled for another computer - CPC, C64, MSX, PC and the
  rest - is now refused at boot with NextDAAD: DDB wrong machine - E4
  rather than loading and then behaving strangely. The kit compiles for
  the Spectrum already, so this only bites on a database that arrived
  from elsewhere. See getting-started.md for the full
  list of boot messages.
