A wrap-around shot involves firing a beam shot diagonally off the far right side of a room to open a door that is on the far left side of a room.
Any variation of Charged Wave should be able to perform this technique, although whether or not Spazer or Plasma are involved will affect what positions the beam can be fired from to still connect with the target door.
It experiences the most use in categories involving a large amount of item collection, such as 100% Items, 100% Map, and Reverse Boss Order. The two rooms where this is primarily performed are the Landing Site, to open the door leading to the Gauntlet Energy Tank so that Samus can shinespark through towards it, and Crocomire's Room, to open the door leading to his Power Bombs so that Samus can shinespark or Space Jump through towards it.
Beams disappear as soon as they are off-screen, so the beam must be at full width as it reaches the edge of the screen in order to trigger the door. You should hear the sound of the door opening if performed correctly.
Generally, this does not work in reverse order (firing a beam shot diagonally off the far left side of a room to open a door that is on the far right side of a room), but it might be possible under extremely specific circumstances.
