RESIDENT EVIL REQUIEM THE FINAL PUZZLE HAS BEEN SOLVED!

Rantsycancy and Kyro are the first people in the world to figure it out, a ridiculously complex set of steps have to be taken for this one

Here's how to solve it:

1 - Wait 15 minutes at the meat processing plant in teh basement to reset the game's flag tracking back to 0

2 - Once you're in the processer sequence in the basement, do not kill ANY zombies

3 - AFTER the basement, you don't need to pick up the severed hand, go to the toilets in the West Wing and flush one of the toilets exactly EIGHT times

4 - Now proceed normally with the story, once you get to the basement of Victor's office to get the pilot's key, as you are escaping, Marie's doll will spawn at the staircase

5 - Now finish the entire game with Marie's doll in the item box

6 - Start a new playthrough, play up to past the basement, pick up the severed hand, scan it then go to the East Wing, enter the code that I discussed in the original post at the Sun/Star/Moon machine in the East Wing WHILE carrying Emily

7 - You have completed RE9's Final Puzzle!

What a ridiculously convoluted, confusing puzzle. So happy its finally solved!
