I was wondering if any progress had been made regarding the "Community database" that would reference the controls mapping ? Has anybody started one ?
From looking around and reading this post, this is what i gathered (might be helpful for people like me just starting to look) :
SirPoonga's Controls.dat
http://controls.arcadecontrols.com/
This seems to be based on Mame 0.141 so quite outdated
Mame's portname plugin
https://github.com/cracyc/mame-portnames/tree/master
Last updated in 2018
Progetto snaps command.dat
https://www.progettosnaps.net/command/
Seems to still be updated
Contains also some move lists, cheats and others
I am more interested in arcade controls so i have not looked around for any other type of database but i might have missed something.
