Arcadeemulointi, or arcade emulation, refers to the process of recreating the functionality of arcade game hardware on a different platform, typically a personal computer or a modern gaming console. This is achieved through software known as an emulator. Emulators work by simulating the behavior of the original arcade machine's central processing unit (CPU), graphics processing unit (GPU), sound hardware, and input systems.

The primary goal of arcade emulation is to allow users to play classic arcade games on modern devices, preserving them for future generations. These games, often developed in the 1970s, 80s, and 90s, are no longer readily available on their original hardware. Emulation provides a way to experience these titles as they were originally intended, often with enhancements like save states, graphical filters, and controller remapping.

Developing an accurate arcade emulator is a complex undertaking. It requires extensive knowledge of the original hardware architecture and programming. Reverse-engineering the original arcade machine's ROMs (Read-Only Memory) containing game code and data is a crucial step. Legal considerations surrounding ROMs can be complex, as they are often copyrighted material.

Several popular arcade emulator projects exist, each focusing on different sets of arcade hardware. These projects are typically developed and maintained by dedicated communities of enthusiasts and programmers. The accuracy and compatibility of emulators vary, with some being able to run a vast library of games flawlessly while others may struggle with specific titles or introduce graphical or audio glitches. Arcade emulation plays a significant role in retro gaming and game preservation efforts.
