Beatmania | CHD errors

[ignition-one]

Alright, so I've got all the things I need, including the CHD dumps, but I am not 100% clear on to how to I have to order the hierarchy of files.

From what I've been told, this is how I should have it set up (and I do):

But, now, this is where I get confused. MAME(MacMAME) shows two sets for each Beatmania Mix:

While I'm not sure which I'm supposed to load, both give me the "xxxxxx.chd not found", which clearly isn't the case.

Is this an issue with MacMAME or have I mislabeled something? Thanks!

MAME just show the clone sets which you miss some CHDs, this is usual when you got other sets of the same game (driver).
I think your CHDs and ROMs are placed right, whenever "Bemani" is one of your rom paths and the CHDs match with that set/folder
