# Final Fantasy Tactics: a matching PlayStation decompilation

> Final Fantasy Tactics decompilation reconstructs the North American PlayStation release SCUS-94221 as C and assembly source. The author reports that its build reproduces the original disc byte for byte; build checks compare functions against stored hashes, and the repository includes architecture and game-mechanics documentation. It extends an acknowledged earlier decompilation.
