Editing the Storyboard
MANY YEARS AGO PRINCE DARKNESS GANNON STOLE ONE OF THE TRIFORCE WITH POWER. PRINCESS ZELDA HAD ONE OF THE TRIFORCE WITH WISDOM. SHE DIVIDED IT INTO 8 UNITS TO HIDE IT FROM GANNON BEFORE SHE WAS CAPTURED. GO FIND THE 8 UNITS LINK TO SAVE HER.
Each value generates four different colors and splits them among eight different letters. For example, the value B6 would result in this:
<Red><Red> <Blu><Blu> <Grn><Grn> <Red><Red>
If this hex value was applied to the first two lines of the original prologue above, it would apply color in this way.

Editing in-game text
The hex value 25 is a <BLANK> letter - if you start a message with a bunch of them, you won't hear the game typing out spaces, but you can still use them to center your message.
The hex value EC is interpreted as a period and tells the game to stop interpretation.
The game uses bitwise logic to interpret text bytes. The six least significant (rightmost; d5-d0) bits code for the letter/character tile to be utilized. This allows for a range of 64 characters, from $00-3F. The two most significant (leftmost; d7-d6) bits are used to tell the game to end that current line-write, and how to proceed from there:
00 = Keep writing on same line.
01 = Next character starts 3rd line.
10 = Next character starts 2nd line.
11 = Message end.
This creates four blocks of hex values: normal characters [00 to 3F], second line enders [40-7F], first line enders [80-BF] and overall message enders [C0-FF]. This means that if you write a message that is two lines long, the last letter of the first line has to be written using the [80-BF] set of letters so the game doesn't keep typing stuff offscreen. (You can make the second line of text appear where the third line would normally be by using a value from the [40-7F] set to end the first line.)
$2C = 00101100 = Normal period.
$6C = 01101100 = Second line-ending period.
$AC = 10101100 = First line-ending period.
$EC = 11101100 = Message-ending period.
If you programmed your table file to have capital letters be mapped to the first range and lowercase letters be mapped to the third range, the code from the RO< would read like this:
(ROM Offset 418B) <BLANK><BLANK>BUY MEDICINE BEFORe<BLANK><BLANK>YOU GO.
