It's Raining Ki [Vega]

This code will make all Ki Blasts rain in from above, like a meteor shower. There are two different configurations to this code. 1st config effects both 1P & 2P/COM. 2nd config makes you choose between 1P or 2P/COM via the X value.

X values (2nd config only):
0 = 1P
1 = 2P/COM

1st config

32-bit RAM Write (present on both configs, so it will only be listed here):

At Unused EVA address 0x800007D8, single float value of -1000 is written. By applying this to the Ki Blast's normal Y starting coordinate, it will make the starting location rise up toward the sky. Enough to where, you can' see it in Split Screen regardless of how far away players are from each other. Thus it makes the appearance of Ki Blasts drop down like rain/meteor showers.

#Hook notes; Hook only executes once for initial Ki launch.
#Also note, at this when Hook is executed. Ki Current XYZ (2nd line in struct) is same as Start XYZ (1st line of struct). To make effects take place in game, we need to write to the Current XYZ, NOT the Start XYZ. 

#r31 = points to start of KiXYZStruct
#f0 and f1 safe for use
#r3 safe for use if used before Original Instruction

#Load Ki Blast Starting Y Coordinate (we can load it from line 1 or line 2 of Struct, it doesnt matter, we'll do line 2)
