Chrono Tales: a browser world viewer built from decoded GBox2 archives

Chrono Tales reconstructs part of the 2012 MMORPG as a three.js browser world viewer using terrain, scenery and a character decoded from the original GBox2 archives. Its Python toolchain extracts .gpak archives, decodes game formats including maps, meshes and animation clips, and exports glTF assets. A format specification records findings from static analysis of chronotales.exe.
