EarthBound/ROM map

This page needs to be formatted a bit differently. The general information on ROM maps should go on its own page.

The ROM Map is a linear breakdown of the hard-coded data in the EarthBound ROM. For the purposes of this database, it serves as a jumping-off point to more specific documents regarding each identified block of code.

Notes on the ROM Map

Reading the data

The ROM Map breaks down the entirety of EarthBound's raw code into specific block by function and type of data. The start address and the end address of each block are given, plus a total byte size (shown in parentheses). All addresses are raw hex format, assuming a 24 Mbit headered ROM. Following the location and size is a brief description of the data contained within. The descriptions are linked to seperate topics with details on each block.

Categorization of blocks

Note that the categorizations below are meant strictly as a means of demarking various areas. The label given does not neccessarily mean that all the data is logically grouped in that category. For example, music and sound data are scattered throughout the ROM. Please take any seeming incongruities between actual data and the categories in stride.
