iidx-db

iidx Chart Database.

iidx.directory is currently live with the data for Infinitas. Arcade data might be added in the future.

Obtaining the raw data

To obtain the raw song / chart info for Infinitas, we use Reflux which reads it from Infinitas memory.

In the Reflux config.ini while, we must set Debug.outputdb=true.

The output is written to the file songs.tsv which will exist somewhere inside the project build when run via Visual Studio.

By default, Reflux writes the song id, title, english title, artist and genre. We made a small edit to the code to write additional columns for the export. We also parse the unlock info before writing the tsv.

Utils.GetUnlockStates();

/* Primarily for debugging and checking for encoding issues */
if (Config.Output_songlist)
{
    List<string> p = new List<string>() { "id\ttitle\english_title\tartist\tgenre\tlevel\tnotes\tfolder\tbpm\tunlockType" };
    foreach (var v in Utils.songDb)
    {
        p.Add($"{v.Key}\t{v.Value.title}\t{v.Value.title_english}\t{v.Value.artist}\t{v.Value.genre}\t{String.Join(",", v.Value.level)}\t{String.Join(",", v.Value.totalNotes)}\t{v.Value.folder}\t{v.Value.bpm}\t{v.Value.type}");
    }
    File.WriteAllLines("songs.tsv", p.ToArray());
}
