How do you remove load times when submitting a time? Does PC Autosplitter do that?

Yes, the PC autosplitter linked in the resources is a load remover, too, but the timer you use must be pausable to remove the load times. You could also use the autosplitter in Livesplit, which you can download via the splits settings when you set the game to Rayman Legends. That is a autosplitter and load remover, too. To be exact, the Livesplit Autosplitter is technically not a load remover, it uses ingame time, so it should be more precise.
