PITFALL! for the Atari ST
Port of Activision's Pitfall! (Atari 2600, 1982, David Crane)
By Tim Kovack 2026
================================================================

Files
  PITFALL.PRG    run from the desktop
  PITFALL.ST     720K disk image. PITFALL.PRG is in the root and in \AUTO,
                 so it starts automatically when you boot from the disk.

Requirements
  Any ST/STE/Mega ST with 512K or more and a colour monitor (low resolution).
  The program switches the display to 60 Hz and restores everything on exit.

Controls
  Move           W A S D or cursor keys or joystick (joystick port 1; the
                 mouse port is ignored)
  Jump           Space or fire button
  Start          fire starts a game when none is running
                 (also restarts after game over)
  F1             Game Reset          F2   Game Select
  F3             Colour              F4   Black & White
  F5 / F6        Left difficulty A / B
  F7 / F8        Right difficulty A / B
  Esc            Quit to desktop

How it works
  The 2600 game logic is statically recompiled from the original 6502 code
  to 68000, so it plays exactly like the original (verified against a 2600
  reference emulator: identical game RAM after 3,000-5,000 frames of play).
  The 2600 display kernel was rewritten natively. Game logic runs in the
  vertical-blank interrupt, always at the 2600's 60 frames per second;
  the picture is redrawn as fast as the 68000 allows (roughly 25 updates
  per second during play, more when little moves), skipping only display
  frames, never game frames. Sound is translated from the TIA to the YM2149.
