Metal Slader Glory/ROM map

The following article is a ROM map for Metal Slader Glory.

ROM

Note: * Size = EntryNumber * 3 - 1

* 0x001CC5 to 0x003D5B (02096) = Primary pointer table for the entire game's dialogue. Pointer entries are three bytes each. Text is scattered around the ROM haphazardly. Length bits in the address pointer are zeroed out for every entry. The byte 00 is used as a delimeter.
* 0x003D5C to 0x005F57 (021FB) = Primary pointer table for dictionary. Pointer entries are three bytes each. Text is scattered around the ROM in small patches. 
* 0x05485C to 0x07400E (-----) = Dialogue region.

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 the bit, because 00 is a valid CHR tile value.

Address layout (in bits)

The Stardust Crusaders translation uses the length bits to use the translation's expanded ROM space. This is only for the dialogue. The dictionary needs these bits.

a

x

, y , z = Address bytes

     dddddddd = x4 x5 x6 

z1 z2 z3 z4 z5

     eeeeeeee = y1 y2 y3 y4 y5 y6 y7 y8

     Translation:

     dddddddd = x4 x5 x6

     eeeeeeee = y1 y2 y3 y4 y5 y6 y7 y8

     Final address = cccccccc dddddddd eeeeeeee
