Preview limitations

The timing button switches between Original (~60Hz) and System (60Hz). Original preserves the cabinet clock. System slows the nominal update opportunities from 61.523 Hz to 60 Hz, with matching audio consumption; completed vector lists still follow the original scheduler. Your choice is saved for Space Duel.

Control-flow coverage is incomplete; an unimplemented path stops with a diagnostic fault. Vector timing, raster appearance and audio mixing retain documented approximations. High scores persist in this browser through an explicit host adaptation. Please report a fault with the output of render_game_to_text().
