Certainly! If you're using Recalbox to play MAME arcade games, here's how you can exit out of games:

Press the designated hotkey combination on your gamepad. By default, this is typically "Select" + "Start" buttons.

This should bring up the menu, allowing you to navigate and exit the game.

Remember, the exact process might vary depending on your specific Recalbox setup and configuration. If you've customized your controls or settings, the hotkey combination might be different.
