I am a new speedrunner, I was about to submit my first speedrun but there's a RTA and LRT. I cant understand what these mean and are they really important or not. So can anyone explain these to me. Another question if I have issues using timer applications, can I just use a greenscreen timer from Youtube which is aligned with the video. thanks

You don't need a timer on screen to submit, we retime every run anyway.

LRT basically just means removing the time you'd spend waiting for the game to load. We do NOT time any runs using LRT, so you should leave that empty. We just cannot remove the option for LRT because of src.

RTA is just the default timer you probably used anyway, so fill that in.
