EBM

This document describes the EBM file format used in the Ragnarok Online client.

Contents

EBM files contain compressed image data and are used exclusively to represent guild emblems.

Layout

The binary layout is irrelevant in practice: They're Bitmap (BMP) files compressed with the standard zlib DEFLATE algorithm.
