The port reads the game's files from data/ rather than from a disc. dcdata reads the ISO 9660 tree itself (the PAL prototype's UDF bridge does not parse), or a directory already holding DATA.DAT and DATA.HD2, parses the index as PAL's InitCDFile does and writes every file under its lowercased path. Files already present at their size are kept, so a rerun is cheap, and the index is copied alongside for the game to cross-check. The core is a header so the port's tests and data reader can use it without linking the tool.
