@poppadum Exiting games like MAME arcade titles on Recalbox is a common question, but the process is straightforward once configured properly. The most reliable method is using Hotkey + Start simultaneously, which acts as a universal exit command. By default, the Hotkey is mapped to the Select button, so pressing Select + Start together should bring you back to the main menu.
If this doesn’t work, it’s worth rechecking your controller settings. Navigate to the controller configuration in Recalbox and ensure the Select button is assigned as the Hotkey. For those with a keyboard connected, the Esc key is another quick solution to exit a game visiting this link https://forum.recalbox.com/topic/30720/how-do-i-exit-out-of-all-games-especially-mame-arcade-games/bitlifegame/.
Pro tip: Take a moment to familiarize yourself with the Hotkey mapping; it’s a game-changer for navigating Recalbox seamlessly!
