BOOT.BIN is WotL's main executable file. It's an elf32-little MIPS file with .text, .data and .rodata sections.
This file contains most of the game code, as well as a large number of data tables.
Because of the way the new content has been patched on top of the old PSX data, a lot of tables are split into old and new versions, with small functions providing an abstraction, making them appear as an united whole to the rest of the game.
The offsets presented here are from the U version.

To get the runtime address of a symbol, simply add the virtual address of it's section to the symbol's section offset. Same for the file offset.
