In a non-merged set, every single game zip file stands entirely on its own. It contains the parent game files as well as all necessary clone, regional, and BIOS files needed to run that specific version.

| Type | How It Works | Pros | Cons | | :--- | :--- | :--- | :--- | | | Every single game (including all its variants, known as "clones") is stored in its own self-contained ZIP file. | Maximum Simplicity : Just download the game you want and play it. Easy Management : You can add or remove individual games without worrying about breaking anything. | Largest File Size : This set contains the most data, as many files are duplicated across hundreds or thousands of ZIPs. | | Split | The "parent" ROM (the main, original version of a game) is a complete set, while "clone" ROMs (regional variants, bootlegs, etc.) contain only the files that are different from the parent. | Smaller Than Non-Merged : Reduces file duplication, saving significant disk space. | Dependency : A clone won't run if its parent ROM isn't present. If you delete a parent game, all its clones become unusable. | | Merged | All clone ROMs are stored within the parent game's ZIP archive. | Most Space-Efficient : This is the smallest possible set. | Difficult to Manage : It's the most complex format and is generally not recommended. | Download the latest official release of MAME from
