MM2 buebeam damage transfer

[Wiki blurb from 2017]

When a Crash Bomb is exploding it's possible to apply it's damage to other nearby enemies by taking damage yourself within a certain distance. In the speedrun this is utilized to kill an extra turret in buebeam trap. The allowed distance from the original explosions depends on certain values in memory that get set whenever you take damage. The general method is to take damage in a specific way that is known to produce good values, then apply the damage in another specific place where you know those values will suffice. There are theoretically a large possible of possible specific setups (which you can explore with this FCEUX script[http://tasvideos.org/forum/viewtopic.php?p=255844#255844]), but two are commonly seen in RTA.

The easier and slightly slower one is to stand close to the upper one of the two turrets on the right wall, place a bomb inside it, then jump and fall on it while touching the wall. This will set the damage transfer distance to 30 pixels horizontally and 105 vertically, letting you damage transfer from the bomb you just set to the bottom turret.

For the faster one, in the beginning of the fight after the initial wall+turret kill, place a bomb next to the middle turret without killing it, and stand on the middle platform facing right with your left foot one pixel over the ledge (TODO image). Wait for the turrets to shoot, and taking damage from the bullets here will set the damage transfer distance to 80 pixels horizontally and 32 vertically. Proceed as normal, until the wall double kill (or top right wall kill if you miss the double). Now if you managed to avoid damage and still have the values you set up earlier, you can transfer the damage from the wall kill to the top right turret.
