Rainbow Arrows

On the Subject of Rambunctiously Automating Rainbow Arrows

I will solve this module with the power of friendship and this gun I found!

See the original manual for instructions related to the module.

N

Use the right digit of the display as the column, and the last digit of the serial number as the row.

0		1		2		3		4		5		6		7		8		9
0	SE	0	S	0	SE	0	S	0	E	0	NE	0	NW	0	S	0	S	0	SW
1	NE	1	NW	1	SW	1	E	1	NW	1	SE	1	N	1	S	1	W	1	W
2	W	2	SE	2	NE	2	NW	2	S	2	N	2	W	2	NE	2	SE	2	S
3	NW	3	NE	3	N	3	NW	3	SW	3	W	3	W	3	SW	3	NE	3	S
4	N	4	N	4	NW	4	NW	4	NW	4	SW	4	NW	4	S	4	N	4	SW
5	S	5	NE	5	NW	5	SW	5	E	5	NE	5	S	5	NW	5	NE	5	E
6	S	6	N	6	N	6	N	6	W	6	W	6	SW	6	E	6	N	6	E
7	SW	7	NW	7	W	7	NE	7	W	7	S	7	W	7	SE	7	NW	7	S
8	S	8	NE	8	N	8	SW	8	E	8	W	8	SE	8	NW	8	SE	8	NE
9	SE	9	N	9	N	9	N	9	W	9	W	9	S	9	NE	9	N	9	SW

NE

Press the arrow that is n steps clockwise from white, where n is the column number of the range containing the display.

0	1	2	3	4	5	6	7
0–5	6–16	17–28	29–39	40–50	51–61	62–73	74–84
85–95	96–99

If this is the 4th rule, press the opposite arrow (NE <> SW, etc.)

E

IF BATTERY HOLDERS >= PORT PLATES:

Ind	Display % (Batteries + 1) = 0				Else
	Par or Ser		Else		Par or Ser		Else
	Diag	Else	Diag	Else	Diag	Else	Diag	Else
0	NW	W	SW	S	SE	E	NE	N
1	NW	NW	W	W	SW	SW	S	S
2	NW	SE	NW	SE	W	E	W	E
3	NW	SW	SE	NE	NW	SW	SE	NE

ELSE:

Ind	Display % (Batteries + 1) = 0				Else
	Par or Ser		Else		Par or Ser		Else
	Diag	Else	Diag	Else	Diag	Else	Diag	Else
0	NW	W	SW	S	SE	E	NE	N
1	SE	SE	E	E	NE	NE	N	N
2	SW	NE	SW	NE	S	N	S	N
3	W	S	E	N	W	S	E	N

Par or Ser: Is a parallel or serial port present on the bomb?

Diag: Has a diagonal arrow been pressed yet?

Ind: Number of total indicators

SE

If this arrow is white, press it.

Otherwise, starting from the last pressed arrow, go counter-clockwise until you reach an unpressed arrow.

Then, move clockwise a number of arrows equal to the number of arrows you’ve pressed, and press the arrow you end up on.

S

Assign each arrow to a letter from A–H, with the white arrow being A, and go clockwise from there. Create the string “ABCDEFGH” (“ABCDEFGH” if counter-clockwise) and modify it as follows:

Move any letters that are present in the serial number to the front, and put them in the order they first appear in the serial number.
If the last digit of the serial is even, move a number of characters from the end of the string, equal to the first digit of the serial, to the front of the string, maintaining their order. If the first digit is 9, use 1.
If there is an odd number of batteries, move the characters in odd numbered positions to the front of the string, maintaining their order.
If N or S are white, reverse the string.

Press the arrow that is assigned to the nth character in the string, where n is the digital root of the display, minus 1. If n is <1, use 1.

SW

Observe the below table. For each instance of a “[Module] Arrows” on the bomb, award the respective row one point. Compare each module name to the serial number, and award one point to the respective row for each letter in the name that appears in the serial number.

Press the arrow color in the row that scores the most points. If there is a tie, use the tied row closer to the top.

MODULE	LETTER DISTRIBUTION	COLOR
RED	Dx1 Ex1 Rx1	RED
ORANGE	Ax1 Ex1 Gx1 Nx1 Ox1 Rx1	ORANGE
YELLOW	Ex1 Lx2 Ox1 Wx1 Yx1	YELLOW
GREEN	Ex2 Gx1 Nx1 Rx1	GREEN
BLUE	Bx1 Ex1 Lx1 Ux1	BLUE
INDIGO	Dx1 Gx1 Ix2 Nx1 Ox1	PURPLE
PURPLE	Ex1 Lx1 Px2 Rx1 Ux1	PINK
DOUBLE	Bx1 Dx1 Ex1 Lx1 Ox1 Ux1	WHITE

W

For each letter in the serial number, excluding duplicates, look it up in the below grid. Award one point to each cell which contains the letter. If any cells are tied for the most points, use the one that comes first in reading order. This is the winning cell.

Observe the winning cell in the grid. Modulo the display by 26, and add 1. Locate the cell adjacent to the winning cell which contains the smallest number that is greater than or equal to the calculated number. If all numbers are smaller than the calculated number, use the smallest number. The grid does not wrap around.

Press the arrow that matches the direction you would need to move to get from the winning cell to this new cell. (If you prefer the way the original manual does this, the starting letter is underlined for convenience.)
