The problem with the tool, sadly, is that it is highly unstable and most of its usefulness has been outdone by CoilSnake, which we recommend you use. This tool, written in Java, allows you to edit almost all data available in the EarthBound ROM.

PK Hack was the premier EarthBound hacking utility available anywhere. In order to do any tile and map editing with CoilSnake, you will also need to download EbProjEdit version 1.3.1. Be sure to check out the Tutorials section below for information on just how to use this thing. This basically allows for bigger, yet cleaner modifications to the EarthBound ROM, and it’s all neatly placed in a project folder. CoilSnake automatically takes care of sorting the new data through the ROM and changing pointers to refer to the new data.

When done, you can import the data back into the ROM. You can then edit this data with your favorite text and image editors. CoilSnake avoids PK Hack's data overwriting by just taking the data out of the ROM. As its description would imply, CoilSnake can extract and insert data from the EarthBound ROM, such as images and table data. CoilSnake is a new data extraction/insertion utility for EarthBound written in Python.
