Timer starts when confirming modifiers after selecting New Game and ends on the final hit of Wily. Overall options & modifiers must be shown at the start of the run.
MM4 (Roll, Normal, Default) rules: Played on the Normal difficulty as Roll with default gameplay options/modifiers. This means no fast screen transitions, turning off boss intros, full arsenal, air sliding, burst chaser, etc. Music & control options are excluded from this as they don't impact gameplay.
