Arcade machines rely on modular input systems to provide players with intuitive and responsive controls. The most common types include:

1. Joystick Controls: A staple in arcade gaming, joysticks offer precise directional input for games like fighting or classic shooters.

2. Button Panels: These feature multiple buttons for actions such as jumping, attacking, or special moves, often arranged ergonomically.

3. Trackballs: Used in games like "Centipede" or "Golden Tee," trackballs allow smooth, rolling movements for cursor or ball control.

4. Spinners: Found in games like "Tempest," spinners rotate to control on-screen movement, ideal for racing or puzzle games.

5. Light Guns: These specialized inputs detect screen shots, popular in shooting games like "Time Crisis."

These modular systems ensure versatility and customization, catering to diverse gaming experiences. Whether for retro or modern arcades, choosing the right input system enhances gameplay and player satisfaction.
