Hello, I'm interested in starting speedrunning this game and I see that other people are using autosplitters with livesplit or something. Are the videos I'm seeing with these splits just edited in post or is there an autosplitter available for this game with an emulator or something?

Which video(s) do you think use an autosplitter? I personally just use livesplit on my laptop while playing on DS.

Oh okay. I didn't really realize manual splitting was a done thing. I was mostly going off ILoveSMB's Any% run https://www.speedrun.com/nsmbds/run/zn8jddvz and now that you mention it it does look like the splits aren't frame perfect (no offense :)) and are all in the middle of loading screens so manual splitting actually fine.

Thanks :)
