LEGO Star Wars: The Video Game (PlayStation 2)/ROM map

The following article is a ROM map for LEGO Star Wars: The Video Game (PlayStation 2).

This ROM map covers the functions and instructions of the game code. Addresses are from the US release.

This page's format will change as more content is added and documented. There will be a list of hexadecimal addresses, and for each address or range of addresses, there will either be a function header written in C-like pseudocode, a link to more detailed function information when available, and/or a brief description.

Some information about the source code--specifically the names of certain functions and which C file they were located in--can be ascertained from logger messages left in the code. These functions with "official" names will be in bold.
