This is the most critical technical distinction.

MAME ROMs are stored in ZIP archives. To save space, emulation communities created three packaging methods: Mame 2003-plus Reference Full Non-merged Romsets Download

| Type | Description | Pro | Con | |------|-------------|-----|-----| | Split | Parent ROM contains the main files; each clone only contains the files different from the parent. | Smallest file size. | Clones won't work without the parent ZIP present. | | Merged | Parent + all clones compressed into a single ZIP file named after the parent. | Organised for archival. | Browsing clones is confusing; large individual ZIPs. | | Non-Merged | Every game (including clones) is fully self-contained. Each clone has all the files needed to run, even if the parent is missing. | Plug-and-play. You can grab one ROM and it works standalone. | Largest total size (about 30% larger than split). | This is the most critical technical distinction

Why choose Non-Merged for MAME 2003-Plus?
Because most retro handheld users do not want to manage parent files. You want to put sf2.zip (Street Fighter II - Champion Edition) on your SD card and have it run, even if you deleted sf2.zip (the parent, World Warrior). Non-merged gives you that freedom. | Smallest file size

Once you have your .zip files (hundreds or thousands of them), here is how to deploy them.
