I've got my system working - Attract-Mode (v2.5.0) on RetroPie (4.4.3) on Raspberry Pi (3.5B+). I'm using this setup for ARCADE Games (MAME).
I was able to get the CATVER.INI and NPLAYERS.INI to work...but I cannot get the CONTROLS.INI to work -- trying to populate the values for PLAYERS, CONTROL, BUTTONS romlist.
My research is showing that CONTROLS.INI is not supported in Attract-Mode - is that still true?
Any suggestions (step-by-step) on how I can populate those fields in the generated romlist file to be populated so that I can use them in the FILTER/RULE section?
Thanks, Scott (aka "Pinball")
