To use, download the file and save it somewhere, right click on LiveSplit > Edit Layout > Add > Control > Scriptable Auto Splitter > Browse and select this file from wherever you saved it. Then right click LiveSplit again > Compare Against > Game Time. This script should automatically start livesplit upon starting a new game, pause the timer on all loading screens and cutscenes, as well as autosplit on every map change. (does not stop on main menu, or if the game is closed). Unfortunately it cannot autosplit the end split of the run, but it will pause the timer on the ending cutscene, so you can manually split there.
