Document description

This document is for the NES version of SMB3. It basically explains how to change the data of the level pointers so that you can make Mario go to any level you want from any level you want. This document provides you visually easy-to-understand data. This includes the Hex values for the numbers 0 to 255; the data for every map and level in the game (including the original number of 3-byte objects, 4-byte objects, and enemies in each level - this includes the Lost Levels as well); and step-by-step instructions on how to convert between Decimal (Base 10) and Hex (Base 16), as well as what you need to know and do to be able to change a pointer in a level.

This document was created in the hopes that people who are just beginning to ROM hack will easily understand what they need to do when it comes to SMB3 hacking. It can also hopefully provide those who have hacked SMB3 before a useful resource in the situation that they need a reminder with certain information on a specific level.

UPDATE: August 27, 2008 - I only just realized that there is a minor error in the World 2 data table. Instead of “P 2 End 2″, it should read “P 1 End 2″. I won't bother changing this since it was just the name that was wrong and if you really want to, you can fix the number yourself to prevent confusion.
