# doubutsu-no-mori: an early N64 Animal Crossing decompilation

> doubutsu-no-mori is an early matching decompilation effort for the Japanese Nintendo 64 Animal Crossing game. It uses splat to split a user-supplied ROM and builds a decompressed ROM for comparison; the author also planned a byte-matching compressed ROM build.
