Enter ROM menu in arcade games

[fonzman]

Back in Recalbox 3.3 I could enter the ROMs unique menu by pressing hotkey + menubutton. This was necessary to change the number of available players or coin chutes in some arcade games.
In Recalbox 4.1 if I press hotkey + menubutton (default "B") I only see the retroarch menu, but not the ROM menu.

Any suggestions what I am missing here?

In FBA, you can set a certain button configuration in the RetroArch menu, for example holding the Start button, to access the ROM menu. In MAME, you should be able to enter the ROM menu by pressing either L2 or R2.
