This tutorial is for changing the Braille writings on the rocks

or maybe even adding ones

It will be a short tutorial,so here we go:

You got to find the Braille writings you want to change,I'll use the English Sapphire ROM.
First, open Advance Map, and go to the event on these rocks, and find the script location...
Aus Ini => SIEGELKAMMER => SIEGELKAMMER 24.71
Let's check the signature on X: 4 Y: 6,
The script is in 15F0BC(h)
Ok,let's open an HexEditor, and jump to the script's offset.
You'll find these Hex numbers: 69 78 DF 52 1C 08 6D 73
Now,we'll follow after the pointer in there,which is DF 52 1C 08 => switch it back
to an Address,it will be 1C52DF, let's jump to this address.
Hex numbers that were found: 09 06 13 0D 0C 09 01 05 03 FF => FF always means end.
Ok,here's what every byte does:
[Position of the left side of the box from the left edge][Position of the upper side of the box from the top edge]
[Position of the whole box on the screen - X axis - starts: left][Position of the whole box on the screen - Y axis - starts: top]
[Position of the Braille signs on the screen - X axis - starts: left] [Position of the Braille signs on the screen - Y axis - starts: top]
[First Braille][Second Braille][Third Braille]

A little explaination:
[Position of the left side of the box from the left edge] - If you put 00,it will stretch from the left side of the screen til'
the box screen position. If you put 01,it will move in one pixel from the left to the right,and will stretch til' box screen
position. the more you're adding numbers,the more the left side of the box will get shortened to the right side of the screen.
[Position of the upper side of the box from the top edge] - the same,only this time,it will start from the top edge,and it will keep
stretching to the downside...
[Position of the whole box on the screen - X axis - starts: left] - what is the position of the box you have built on the screen
from left ot right,starts from left,the more you add numbers,the more it will go right.
[Position of the whole box on the screen - Y axis - starts: top] - the same as above,only this time it's at the Y axis...and starts
from the top
[Position of the Braille signs on the screen - X axis - starts: left] - this is where the Braille signs will be on the screen,
from left to right.
[Position of the Braille signs on the screen - Y axis - starts: top] - the same as above,only from top to bottom
[First Braille][Second Braille][Third Braille] - brail signs by numbers,here is the table of what every number means
as a Braille sign:

Structure: [letter][hex number] - you can find how does every letter look in Braille with this picture:

Note: there are unused Braille signs. (I guess these were used in Japanese)

Dots with no meaning,plain dots (00)
A (01)
B (05)
C (03)
D (0B)
E (09)
F (07)
G (0F)
H (0D)
I (06)
J (0E)
K (11)
L (15)
M (13)
N (1B)
O (19)
P (17)
Q (1F)
R (1D)
S (16)
T (1E)
U (31)
V (35)
W (2E)
X (33)
Y (3B)
Z (39)
Period (.) (2C)
Comma (,) (04)
Unused: 02,08,00,0A,0C,10,12,14,18,1A,1C,20,21,22,23,24,25,26,27,28,29,2A,2B,2C,2D,2F,30,32,34,36,37,3A,3C
3D,3E,3F - 40 is just rubbish and so on...

If there's something to fix (unless it's my English lol) in this tutorial,please,let me know,if something is not clear enough.
Enjoy changing Braille!
