A "merged" set consolidates these files, hiding clone variations inside the parent zip file to save space. A "split" set separates them. A "nonmerged" set, however, is the most user-friendly but space-heavy format. In a nonmerged set, every single game—whether it is a parent or a clone—is packaged as a completely standalone zip file. This eliminates the detective work required to figure out which dependencies a specific game needs to run. For the end-user, a nonmerged set offers a "plug-and-play" experience; if you have the zip file, you have the game.

However, the ethical and legal shadows surrounding this search query cannot be ignored. While MAME itself is a legal tool for preservation, the ROMs it runs are copyrighted intellectual property. The distribution of "full nonmerged romsets" via direct links is generally a violation of copyright law. This places the preservation community in a difficult bind.
