| ← | D-Pad Left | Move left |

These bindings cover the 6-button Mega Drive controller. Most older titles only use buttons A/B/C; the extra X/Y/Z buttons matter for Street Fighter II and other 6-button fighters.
Rebind any key from the EmulatorJS in-game settings menu (gear icon → Controls). A connected gamepad auto-maps to the same buttons.
