War of the Lions/BOOT.BIN

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.

.text

Section Offset	Length	Name	C Signature	Description
0x000000	0x98	_EntryPoint	void (void)	BOOT.BIN entry point
0x00B940	0x18	strlen	uint32_t (const char* str)	Get the C string size in bytes
0x0BEDC0	0x0C	GetItemDataMasked	ItemData* (uint16_t item_id)	Fetch the data pointer matching an item ID, masked on the lower 9 bits
0x214600	0x4C	GetItemData	ItemData* (uint16_t item_id)	Fetch the data pointer matching an item ID
0x214DC0	0x80	IsItemInvalid	bool (uint16_t item_id)	True if the item ID is zero, larger than the maximum item ID, 0xFE or 0xFF

.data

Section Offset	Length	Name	C Signature	Description
0x00EC90	0x408	gNewItemTable	ItemData[86]	The item table for the PSP items
0x0DD16C	0xC00	gOldItemTable	ItemData[256]	The item table for the PSX items
