Find your next chart for AstroDX.

AstroDX is a community-built simulator for maimai-style rhythm-game charts. This site, the ADX Chart Archive, is an unofficial index of AstroDX charts with metadata, cover art, and download links.

maimai DX is SEGA's arcade rhythm game, and AstroDX charts recreate its play format. The catalog groups charts by maimai DX versions such as FESTiVAL, PRiSM, BUDDiES, and UNiVERSE.

Open any chart's detail page and use the on-site download button to fetch the chart package built from the remote AstroDX directory.

The .adx you download here imports as-is — no extracting. On iOS, use the Files app to move it into the AstroDX folder itself (not the levels folder inside it). On Android, tap the .adx and open it with AstroDX, or long-press and share it to AstroDX. Launch the game once before your first import. Full walkthrough in the guide.

The archive currently lists 1934 charts across 28 maimai DX version branches, and is updated as the remote directory changes.
