Map Buffer

Map Buffering is a technique that can be used to buffer inputs and/or cause a few frames of lag.

It is done by opening the map, going to the 'world' map, selecting an area that you are not currently in, and then closing the map.

Buffered inputs must be held all the way until control of Samus has been restored.

This can be used to shorten the length needed to store a shinespark as well:
