You were right
I was confused because in recalbox it works a little different
scummvm
| - Monkey Island.scummvm
| | - monkey.scummvm
"Monkey Island" appears in the frontend and the game begins pressing the button
In batocera works as you said
scummvm
| - Monkey Island
| | - monkey.scummvm
"Monkey Island" appears in the frontend, pressing the button leads to the file "monkey" and pressing again the game starts
Thanks friend
