# The Jungle Book: a Game Boy disassembly with level-analysis tools

> The Jungle Book project disassembles the Game Boy game into banked assembly and supplies tools to extract assets from a user's ROM. Its analysis utilities render level maps, decompress LZ77 data, inspect level objects, and export animation frames; the author reports a byte-exact rebuild when the extracted assets are supplied.
