There's two separate pointer processing routines for the dictionary and dialogue. Both are very similar, however, the dialogue pointer routine supports pointers for a 1 MB PRG mapper.

Note:
There's for pointers before 0x0x001CC5. Some are for the title screen graphics, some are used for the credits, screen adjustment screen dialogue, etc. The screen adjustment text is uncompressed.

Pointer structure

Although typically for SNES games, this game uses three byte pointers; however, this game adopts a space saving measure by storing a dialogue entry's length within a pointer. The dialogue's pointers have the length bits zeroed out because it uses a delimeter. The dictionary's pointers use these bits because 0x00 is used for control codes.

Note:
The Stardust translation violates this pointer structure. A handful pointers for the dialogue menu options use the dictionary pointer structure.


Address layout (in bits)

There's two separate pointer processing routines for the dictionary and dialogue. Both are very similar, however, the dialogue pointer routine supports pointers for a 1 MB PRG mapper. It accomplishes this by using a bit used for the dictionary length. The final release uses a 0.5 MB PRG mapper and could have used one pointer reading routine. 

a, b     = length bytes
x, y, z  = Address bytes

a1 a2 x1 x2 x3 x4 x5 x6      y1 y2 y3 y4 y5 y6 y7 y8     b1 b2 b3 z1 z2 z3 z4 z5

Length   = 		-  -  - a1 a2 b1 b2 b3
Address  = 
     
     Dictionary:
     cccccccc =  0  0  0  0  0 x1 x2 x3
     dddddddd = x4 x5 x6 z1 z2 z3 z4 z5
     eeeeeeee = y1 y2 y3 y4 y5 y6 y7 y8
     
     Dialogue:
     cccccccc =  0  0  0  0 a2 x1 x2 x3
     dddddddd = x4 x5 x6 z1 z2 z3 z4 z5
     eeeeeeee = y1 y2 y3 y4 y5 y6 y7 y8
    
     Final PC address = cccccccc dddddddd eeeeeeee
