you can try running livesplit in administrator mode

thats a good question matte, I can't seem to find a way.

here is a .rar file with the levels: https://drive.google.com/file/d/0ByiSZcL8lyyFZ3plZ1dZYW9ZN0U/view?usp=sharing

If these sound fun to you don't let that stop you from trying them regardless if there is a leader board for them. I think it would be a lot more likely to see these categories on the leader board if there were more people running them.
