General (SP and DP)

BemaniWiki 2nd (Japanese)


De facto standard place for all BEMANI related information. IIDX.org owes a lot to BemaniWiki.

textage (Japanese)

IIDX tier list (len-ch.com) (Korean)


Replacement for insane.pe.kr (which is no longer maintained). This one is being actively updated. Tier lists for SP12H/SP12/SP11H, DP12/11/10.

INFINITAS Rank Table (Korean)


Replacement for insane.pe.kr but this one is focused on Infinitas song list. Tier lists for SP12/11/10, DP12/11/10, DBR.

iidx.me (English)


Score tracker that pulls data from e-amusement.

statistik (English)


User-submitted difficulty rating for charts. Useful for seeing what options other people used. Ratings aren’t super helpful - use other tier lists from below.

remywiki (English)

Notes Radar bot



Data sheet for charts that contribute to the player radar (for CHARGE, CHORD, NOTES, PEAK, SCRATCH, SOFLAN).

FOV Calculator (English)


This is used to calculate FOV values for various racing games, but it can also be used to figure out the screen distance for your home IIDX / BMS setup, in case your monitor is smaller or larger than cab monitors.

For example, Lightning Model cabs have (approximately) 42” monitor at 67cm away from bottom edge of the control deck, which gives RBR value of 0.960. To get an equivalent experience with a 32” monitor, you would put the screen at 51cm away.

Z-i-v Arcade locator (English)


An interactive map of arcades worldwide.
