Since there seems to be some slight activity here now, I thought I'd share my simple auto splitter script I made when I first started running the game: https://pastebin.com/bMnytwX5

Save this as an .asl file, go to "edit layout" in LiveSplit, Add > Control > Scriptable Auto Splitter, and add the file you just made.

Time automatically starts right after you select which mode you're playing on, it splits on every "saving" screen, and time ends on the save screen after you kill the final boss. Makes things a bit easier, and makes your splits way more accurate.
