shows: LEFT for 2 frames, DOWN for 2 frames, then nothing: Pac-Man walks left to the wall at the corner and stays there.

observations:
  Frames are counted from power-on (frame 0). Memory bytes are named by their address; the meanings are working labels
  (Stages C6 and C7, docs\CONTROLS.md and docs\CAPTURES.md), not yet confirmed (Phase F). Every number below was read from the trace.
  - Game Reset on frame 240 starts a game (lives counter reads 3 from frame 240).
  - Play begins on frame 367 (pause flag clears); Pac-Man stands at (76,60), the start place.
  - Joystick on frames 367-369: nothing.
  - Joystick on frames 370-371: LEFT.
  - Joystick on frames 372-373: DOWN.
  - Joystick on frames 374-479: nothing.
  - Pac-Man moves left from (76,60) to (64,60): 12 pixels, first step on frame 371, last on frame 391; frames between steps: 2,2,2,1,2,2,2,1,2,2,2 (2 x 1 frame, 9 x 2 frames); 0.571 pixels per frame
  - Pac-Man took 10 pixel steps on frames when no direction was held (first on frame 375): it keeps going in its last direction.
  - How to check it against the real game: start a game, tap left, then tap down, then let go of the joystick (switch on, press Game Reset, wait for the start tune to end; the frame numbers are counted from power-on at 60 per second; the joystick moves are listed above).
