# ChronoRET: matching 65816 reconstruction of Chrono Trigger

> ChronoRET reconstructs the US SNES release of Chrono Trigger as labelled 65816 assembly. Its build extracts remaining data from a user-supplied ROM, assembles a complete image and compares it byte for byte with the original; progress records separate code matching from data coverage.
