	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 
}
