Hello, my friend rainbowism and I worked on an autosplitter for the Steam version of the game. Currently it only splits automatically when a boss reaches 0 HP, but we're hoping to also have it remove load times and start on character select (he had it working on his stream last night but it doesn't auto start for me as of this post).

Let me know if there are any issues and I'll see if we can get it fixed.

New version of the autosplitter, now removes loading times and starts when you select your character. (Selecting the character may be delayed by a little bit, so you may need to manually add in a small offset in LiveSplit to account for it.)
