Arcade game hardware has relied on various microcontrollers over the years to deliver the fast-paced, responsive gameplay that players love. Among the most common types are the Zilog Z80, MOS Technology 6502, and Motorola 68000.

The Z80 was widely used in classic arcade games like *Pac-Man* and *Space Invaders* due to its simplicity and efficiency. The 6502, known for its role in early home computers, also powered arcade hits such as *Donkey Kong*. Meanwhile, the 68000, with its 16/32-bit architecture, became a staple in more advanced titles like *Street Fighter II*.

These microcontrollers were chosen for their balance of performance, cost, and reliability, making them ideal for the demanding environment of arcade gaming. Even today, they remain iconic in the history of gaming hardware.
