- MOTHER 3 Funland is a modular hacking tool for the game, similar to PK Hack for EarthBound. It can edit most of the uncompressed data in the game, including items, enemies, shops, battle backgrounds, and minor text. Works with both the original Japanese version of the game, as well as the English translation patch.
- The MOTHER 3 Save Editor can be used to hack battery save files.
- The MOTHER 3 Sprite Editor can edit the game's overworld sprites.
An English patch for the game was released on October 17th, 2008. The patch fully translates the game into English. Many of the game's resources were shuffled around in the ROM for various reasons, such as making room for new code or inserting recompressed graphics that didn't fit in their original space. As such, a separate ROM map exists for each version of the translation:
There have also been translation patches released for the following languages:
Miscellaneous hacking information
The ROM uses 32 MB, which is the maximum size for a GBA game; consequently, the ROM cannot be expanded to allow for more/larger resources. Unfortunately, there is very little unused space in the ROM, which severely limits the freedom to hack variable-length data, including dialogue and compressed graphics.
Many parts of the game's RAM are managed dynamically, meaning they shift around unpredictably, making it difficult to come up with a complete, static RAM map. The RAM map, therefore, contains only data blocks that are known to be static.
MOTHER 3 uses the M4A sound/music engine, commonly referred to as "Sappy".
The battery save format can be found at the SRAM map.
The game uses a number of named data structures.
