Pausebuffering

Pausebuffering is a technique where inputs are done via repeated pausing and un-pausing of the game.

This allows you to input frame perfectly if done precisely.

You cannot immediately pause again after unpausing and must wait a while, here are the frame timings for repeatedly pause buffering a single input

You unpause on frame 0, it takes in total 10 frames before control is returned.

Frame	Status
0	Starting to unpause. Control is removed.
1	No control
2	No control
3	No control
4	No control
5	No control
6	No control, first frame you could buffer pause (start holding it) and inputs (you can hold both they should be accepted)
7	No control, second frame of buffer
8	No control, third frame of buffer
9	No control, fourth frame of buffer
10	Control returned; first frame of gameplay resumed, fifth frame of buffer
11	First frame that you can pause if the button is held down.

Since you can start holding pause from frame 6 till 11 the buffer window for a pausebuffer is 6 frames (5+1).

This works because pausing is instant and the game will pause on frame 11 before executing the frame of gameplay.
