How do you get a speedrun timer?

How do you get rick rolled?

How do you install a tas on chromebook?

1. Install Livesplit - http://livesplit.org/

2. Be an idiot

3. I don't know much about TAS speedruns, I'll learn more.

For the timer you can just have a stopwatch (like the google one) in a different window

If you want to retime runs, use either of these retiming tools: https://slashinfty.github.io/yt-frame-timer/ https://github.com/Slush0Puppy/retime

Also https://somewes.com/frame-count/ it's mostly for SMB1 and SMB2J speedruns but it can just be used for retiming speedruns in general
