This is great . While a little time consuming - saves me a lot of space instead of having multiple separate states of Demul set up per system (Naomi, atomiswave, dreamcast) - let alone per game game. Honestly, I must have had over 20 separate folders with separate Demuls set up for different control configurations.
I was able to take you steps to copy both the demul.ini and the pad.ini (controls) in the same instruction so general settings and specific controls can be setup per game (especially useful for Naomi).
Thanks for the detailed explanation - just a note in step 4 - choose the folder not the .ini files itself in the last bit of code or it will open the document up. I know you do clarify in the next step- but for those like me that don’t read things properly it might be worth pointing out. Thanks again.
