A note on old versions
For the old bases (97d, 0.99B and 1.0) we only read tables whose columns are documented in the file itself. In the Season 7 and Season 11 bases, items, monsters and skills are stored with Korean names and were not read. In all these cases “—” means "not read", not "does not exist". The documented 97d base comes from a customized server.
