};

};
 
struct h3def_header {

Archive formats

Format LOD and PAC

struct h3lod {
	uint32_t magic; // always 0x00444f4c, that is, a null-terminated "LOD" string
	uint32_t type; // 200 for base archives, 500 for expansion pack archives, probably completely arbitrary numbers
	uint32_t files_count; // obvious
	uint8_t unknown[80]; // 80 bytes of hell knows what - in most cases that's all zeros, but in H3sprite.lod there's a bunch of seemingly irrelevant numbers here, any information is welcome
	struct h3lod_file[10000]; // file list
}
 
struct h3lod_file {
	char name[16]; // null-terminated, sometimes null-padded too, sometimes padded with, well, something after the null
	uint32_t offset; // includes the header size, no preprocessing required
	uint32_t size_original; // before compression, that is
	uint32_t type; // what's in the file - probably not used by the game directly, more on that below
	uint32_t size_compressed; // how many bytes to read, starting from offset - can be zero for stored files, use size_original in such case 
}

Format VID

struct h3vid {
	uint32_t files_count;
	struct h3vid_file[files_count]
}
 
struct h3vid_file {
	char name[40];
	uint32_t offset;
}

Note: Archive VID doesn't contain information about file's size. For h3vid_file[x]:

Size = h3vid_file[x+1].offset - h3vid_file[x].offset.

If we read last file in archive:

Size = archive_size - h3vid_file[x].offset.

Format SND

struct h3snd {
	uint32 files_count;
	struct h3vid_file[files_count]
}
 
struct h3snd_file {
	char name[40];
	uint32 offset;
	uint32 size;
}

Note: For some reason entries in snd have format NAME(null)WAVRUBBISH....
