I'm not really sure its required because every time I TRY to do it, it just fails. If it is required, then I'll just have to try something else to get it to work.

i don't know what that is but if it has anything to do with livesplit then no because you are required to use the in game timer for runs

oh ok

A) do not announce submitting runs, B) No, using splits.io is NOT required for ANY speedgame, including the FNaF games.

Sorry. Thanks for the advice though

You're quite welcome.
