These are the default keys. Every arcade board has a different number of buttons and means different things by them. The rows above are buttons 1–6 on the board: on Neo Geo boards (The King of Fighters and friends) A/B/C/D are buttons 1–4, Metal Slug uses only 1, 2 and 4 (shoot / jump / grenade), and Pac-Man uses none at all. Six-button fighters with three punches and three kicks (Street Fighter II and the like) get a different layout from the core: light punch U, medium punch I, heavy punch Q, light kick J, medium kick K, heavy kick E. Click the gamepad icon 🎮 in the player toolbar, then “Remap keys” to open the emulator’s own control settings (keyboard and gamepad, saved automatically). Gamepads are detected automatically. On phones you get on-screen buttons.
