• Start: Automatically begins the timer upon pressing "New Game" or loading a save.
• Split: Cuts the segment exactly when a level ends, a boss dies, or a fade-to-white occurs.
• Reset: Stops the timer if you die or load a wrong save.

Why 2021 mattered: By this year, game developers began shipping "speedrun modes" (e.g., Cuphead, Hades). However, for the thousands of indie and retro titles lacking native support, GitHub was the only lifeline for automation. The LiveSplit Server (Discord): The source code for
