Two skins over one game. 1979 is the machine as it was; the remaster is the same rules in cel-shaded vector art with a modern palette. The simulation is untouched - only the paint differs - and the toggle sits under the set. The street is now driven by the game. Before prices are in, the number of people walking on comes from the forecast; afterwards it comes from the glasses that actually sold, so the report shows the crowd you earned. A heat wave has them fanning themselves; a downpour leaves one figure hurrying past under an umbrella. Selling no longer snaps straight to the books. The stand trades for a few seconds first, tally climbing and till filling, which is where that crowd animation pays off. Skippable. The synth grew a kit (pitched-sine kick, snare with body, hats), a sweeping resonant lowpass for the bass, chords and a shuffle - enough for a funk band. The chiptunes stay for the 1979 skin. Boot is now a cassette load, which doubles as the gesture browsers require before audio will play. Fixes found on the way: the picture scaled about its centre while flex auto-margins collapsed to zero on overflow, which pushed the report's buttons off the bottom; and the validation line moved the button when it appeared, so it is now reserved and faded. Sibling tabs in one browser also keep their score tables in step.
