Hello,

I create my own console with 6 playable buttons + 1 insert coin + 1 start player 1 button to play ONLY mame games.
I want to have back the 80’s where I was going to an arcade house and stay there for hours.

I notice that some games I can use the InsertCoin button that is translated to “Selected Button” in RetoPie and some other games not!

Trying to resolve this issue I found that if I use the mame-mamelibretro emultator I could map TAB key where I can configure for each game the InsertCoin button and the all the other buttons.
First question: How can enable this option in Mame-mame4all???

The emulator mame-mamelibretro is not bad and for the games that I choose I found no issues, but, when I leave the game the button configuration is not persistent and I have to do all over again every time that want to play the game.
I try to find how can I save this configuration with no luck and that is why I’m asking you guys.
Second question: How to I persist the button configuration for each game???

tkx all for the help
