# Harvest Moon: Back to Nature: a byte-matching PlayStation decompilation

> Harvest Moon: Back to Nature reconstructs the USA PlayStation release SLUS_011.15 as matching C source. It rebuilds the executable and 13 overlays byte for byte, and can check a full disc image against SHA-1 hashes when supplied with the user's disc. The build records one SDK-word patch and original padding bytes as exceptions.
