I wanted to know if, for new game run, we have to count the run with time spent in menu and loading time or not ? because i downloaded the ultrakill livesplit setting that auto pause and split but it dont take the intro in count, knowing if i should bother to understand how it work to make it run and split for the intro or not :/

Prob not cuz like that’s not the actual game yknow

Please read the rules

Runs are timed with RTA or LRT.
Time starts upon pressing play after deleting the save file.

so yes menu time is counted however load time is not if you are using a load remover in livesplit.

you can also check what other runners are doing if you need an example.

I didn’t knew what LRT was but thanks

LRT just means load removed time. Its everything minus the loads.
