Dear John

For Mame and FBA Libretto games you can change the settings in Retroarch Menu.
You access to this Menu by pressing Hotkey + B

Choose Options and Cabinet in this section you can choose C**ktail or Upright

You have to do this for each rom who supports c**ktail Mode

Regards

Merci pour vos retours.
Je vais attendre un peu et lorsque j'aurai le temps, je testerai sous recalbox.

@ian57 Thanks Ian, I appreciate the quick response.
