In a split set, a clone game or regional variant contains only the files that are different from the parent game. To play the clone, the parent ROM must be in the same folder. Merged Sets

You cannot easily delete clones you don't want without breaking open the archive. Non-Merged Romsets (The Gold Standard) The parent game is in one

| Format Type | How It Works | Advantages | Disadvantages | |---|---|---|---| | | The parent ROM and all of its clones, region variants, and bootlegs are combined into a single ZIP file. | Saves significant disk space (e.g., a 20MB parent might have a 2KB clone). | If the parent is missing or corrupted, none of the clones work. Large ZIP files for each game family can be inefficient for management. | | Split | Each clone or variant is stored in its own ZIP file, but it only contains the files that differ from the parent. The parent ZIP file must also be present for any of the clones to work. | Saves space (smaller clone ZIPs) while keeping each game name separate. | Easy to break: moving a clone without the parent will cause the game to fail to load. | | Non-Merged | Each game is stored in its own ZIP file containing all the required files to run that game, including any ROMs that would normally be in a parent ZIP. However, you may still need a separate BIOS ZIP file (e.g., neogeo.zip for Neo Geo games). | Truly standalone for each game. No need to track parent ZIPs. | Takes up more disk space compared to merged and split formats. | | Full Non-Merged | The same as "Non-Merged," but BIOS files are also included within each game's ZIP file . Every ZIP in the collection is fully complete and can be used entirely on its own, without needing any separate BIOS ZIPs. | The ultimate plug-and-play format. Every game is an independent, fully-functional archive. | Largest file size, as BIOS data is duplicated across hundreds of games that require it. |

The most common format. Clone versions of games (e.g., Street Fighter II: Champion Edition ) do not contain the core files of the Parent game ( Street Fighter II ). To play a clone, you must have both the clone zip and the parent zip in the same directory.

Every single game zip file is entirely self-contained. The clone file contains all the parent data it needs to run independently.

Configure ClrMamePro to use "Non-Merged" mode and disable "Separate BIOS Sets" (this tells the tool you want a Full Non-Merged output). Point ClrMamePro to an existing "Split" or "Merged" MAME set (even a newer one) and tell it to "Rebuild" into a new folder. ClrMamePro will automatically combine and copy only the necessary files to create a perfect, custom Full Non-Merged set.
