Arcade game machines, known for their fixed hardware and software, traditionally limit player-created content or mods due to their closed-system design. Unlike PC or console games, arcade cabinets often lack built-in tools for modding, as they prioritize stability and uniformity across locations. However, some modern arcade systems or emulated platforms allow limited customization through firmware hacks or community-developed tools. Enthusiasts sometimes modify older machines by swapping ROMs or adding external hardware, though this can void warranties or violate copyrights. Dedicated communities share mods for games like "Street Fighter" or "Pac-Man," but widespread adoption remains niche. Ultimately, arcade modding thrives in retro scenes, where players repurpose hardware for creative expression.
