About

The README tracks status per area: the executable is in progress, images and localization files are largely done, Digimon stats, profiles, evolutions and maps are done, while video and many other files are not started.

Getting started

The project is built with zbuild (version 0.1.9), which builds the game's bin/cue files into a build folder, and a compare command checks file checksums. The README warns that building needs several licence files, such as the PS-EXE licences for Europe or North America and an ISO Sony licence, placed in a licenses folder. The final bin/cue is not yet checked because the tool used to build it cannot reproduce the original ISO exactly.

Additional notes

Map tools
A script is provided to stitch the extracted map tiles together into complete maps.
