I'm wondering how you record both IGT and RTA for the run upload. Can someone please tell me how.

can you explain a bit more what you mean? like record both IGT and RTA as in having them both on your livesplit? or something else

When uploading a run, I need both in game time and Time (RTA I guess) How do I get the second one? Do I just time it separately and use that number, or is there another way. Or is it not required?

the mods will time the RTA seperately for you. all you need is the IGT using the autosplitter
