About the routine text from right to left(RTL)

I wanted to add last night that the main entry point for dialogue display and decoding seems to be $C0814C. There are call to code before and after this offset. Here is also some RAM values from the FF6 wiki that could help:

Code:

$BA-$BC Dialog Window
---------------------
    $BA Enable Dialog Window ($01 = open, $80 = close)
    $BB Dialog Window Size ($00: smallest, $05: fully open)
    $BC Dialog Window Top Y Position ($01: top, $12: bottom)

$BD-$D3 Dialog Text
-------------------
    $BD Current Dialog Character
    $BE Next Dialog Character
    $BF Text's Current X Position on Dialog Window ($04-$E0)
    $C0 Width of Current Word
  + $C1 Pointer to Next Tile in VRAM (+$3800)
  + $C3 Pointer to Current Tile in VRAM (+$3800)
    $C5 Text Graphics Needs to be Copied to VRAM
  + $C6 Unused (set to #$0700)
    $C8 Max X Position on Dialog Window (always $E0?)
++ $C9 Pointer to Current Dialog Character
    $CC current region of dialog window that needs to be cleared in VRAM (starts at 9, decrements once per frame)
        9 = none, waiting for keypress
        +-----------+-----------+
        |     8     |     7     |
        +-----------+-----------+
        |     6     |     5     |
        +-----------+-----------+
        |     4     |     3     |
        +-----------+-----------+
        |     2     |     1     |
        +-----------+-----------+
        0 = none, no text displayed (or map name displayed)
  + $CD Character to Display (top byte is for extra characters from FF6j)
    $CF eppppppp
        e: text buffer is empty
        p: dialog text buffer position (+$7E9183)
  + $D0 Dialog Index
    $D2 -
    $D3 Keypress State (decrements when button is pressed or released)
        0 = not waiting for keypress
        1 = waiting for keypress
        2 = waiting for key release
