# Lufia II: portable semantic reconstruction of SNES game logic

> Lufia2Decomp reconstructs Lufia II: Rise of the Sinistrals game logic as a portable C library for SNES recompilation consumers. Its CPU-state and memory adapters preserve observable routine behavior, and a resource tool decodes compressed data from an owner's ROM. The author reports 2,305 functions marked verified by original-ROM differential checks.
