# EKIY / Melis reverse engineering: emulating display firmware and decoding UI resources

> EKIY / Melis reverse engineering runs the original home-screen firmware of an Allwinner F133-B display in a TypeScript application-level emulator. It documents the observed DATAV1.0 UI format, provides tools to read and rebuild UI packages, and records firmware-specific modification findings using a dump supplied by the user.
