@jgeibel My pleasure. Some years ago, I used AM on my Linux PC and laptop before I got my Pi 3b and discovered RetroPie, which seduced me with its all-in-one-package simplicity.
But I still have my MAME 0.185 setup with AM, and I'll never forget this my "first love" among emulation frontends with its unparalleled customisability. 😍
