The character byte's high nibble is usually <code>8</code> (<code>80</code>, <code>81</code>, etc.) but appears in some places as <code>0</code> (<code>00</code>, <code>01</code>, etc.) Not sure yet of the significance of this.
The text position nibble can be either <code>0</code> or <code>8</code>. <code>0</code> vertically aligns the text with the middle of the character picture, and <code>8</code> aligns the text to its top.

Notes

Dialog text has prefix of two bytes and 0E, and is null-terminated. The first byte is the text position and character that speaks. The second byte is the color index for the text. For example: 

82 02 0E 72   6F 6C 6C 2C   20 66 6F 78  ....  6E 20 72 6F   6C 6C 2C 00

text position

The text position nibble can be either 0 or 8. 0 vertically aligns the text with the middle of the character picture, and 8 aligns the text to its top.

Color obviously depends on the palette.

Text is mostly ASCII. # is used as a period.
