About This Site
ADX Chart Archive is an unofficial AstroDX chart archive. It indexes a remote AstroDX directory and serves per-song metadata, cover art, difficulty constants, alias search, in-browser chart previews and one-click downloads for a large library of maimai-style charts.
The site is run at minimal cost with one goal: stay stable and stay around. The catalog updates continuously alongside the upstream directory.
