There are two different types of data structures in MOTHER 3, fixed-length and variable-length. This is the same case in EarthBound, and as we know, PK Hack can edit both of those things. The difference is the premise upon which those things may be edited: in EarthBound, when you change something that’s variable-length, you simply expand your ROM and repoint the data. Easy, right?

Not in MOTHER 3! Nope. Whereas EarthBound may be expanded from 3MB to 6MB, MOTHER 3 is already the maximum possible GBA ROM size. Furthermore, there is hardly any unused space in the ROM to work with; anything that’s already there is currently dotted with data chunks from the English translation. Therefore, it is inherently not feasible to repoint variable-length data in MOTHER 3. This is something that’s not likely to ever change.

Anything that’s compressed is automatically variable-length data. A lot of text banks are also variable-length. The following things are variable-length and thus not editable:

* Maps
* In-battle enemy sprites
* Main text
* Item, enemy and skill descriptions

Supports version 1.2 of the fan translation.
