Reach 4 Player Local Co-op (Split Screen Glitch)

In my opinion this is one of the best glitches of all time, allowing for 4 buddies to play campaign and firefight on one xbox.
I have successfully been able to preform this glitch on my Xbox One, but I can only get it to work with 3 players. I can’t seem to get it to work with 4.
I remember getting it to work with 4 players many years ago (on the 360), and there are videos showing how to do it. I do also remember it being fairly difficult pressing A on the 3rd controller and then A on the 4th right after.

Can anyone else confirm if they can get this to work? (4 player on Xbox One)

Ha that’s cool should of used that glitch to play with my friends. I’ve always wanted to do that!

It’s a nice change of pace after my friends get wrecked when we take things online, haha.

Okay I got it figured out! Slightly press (A) on the 4th controller before the 3rd controller. Trial and error works wonders.

I think it has to do with the way the way the Xbox One emulates the 360 controllers
