Implementation details and use of Plus hardware

  • Mode 1 is used throughout
  • Multiple plus raster interrupts are used to make the shading in the sky
  • Plus sprites are used for the Gremlin logo on the title screen (this actually overlays a smaller, software sprite Gremlin logo), and for extra colours and scenery in the game.

(Sprites are x2 in X and x1 in Y, which give a mode 1 equivalent pixel size)

  • Plus screen split is not used
  • Plus pixel by pixel hardware scroll is used.
  • Plus DMA is not used

The game engine seems to be re-used for Striker in the Crypts of Trogan/Stryker and the Crypts of Trogan as the same programmer did both games.
