Here is a new core for the MiST, the Mattel Aquarius:https://github.com/sebdel/mist-cores/tree/master/aquarius
Latest binary: https://github.com/sebdel/mist-cores/raw/master/aquarius/binaries/core_160908_112119.rbf
The Aquarius gamepads supported 6 buttons and 16 directions so as you can imagine, sacrifices have been done. You are left with up/down/left/right, A=K1, B=K4, Select=K3, Start=K2. K5 and K6 are not so common according to the gamepads overlays that are available here: http://www.geekvintage.com/mattel-aquarius-software.php
I mixed the output of the Aquarius with the AY8910 output so this core has 4 audio channels, unlike the original machine where it was a either/or situation. That does not affect any games and allow to support both audio solution easily.
As far as I know, the AY8910 was never fully exploited back in the days. Nowadays we know better, so... https://drive.google.com/open?id=0ByKxevpwe6i9UXhCQWRhbmJhX1E
