While discussing ROM set sizes is a matter of data science for preservation, remember that downloading copyrighted 3DS ROMs is illegal in most jurisdictions unless you are dumping your own physical cartridges.

When collectors refer to a "complete set," they are almost always referencing the database. No-Intro focuses on "perfect" dumps of cartridges—meaning they are bit-for-bit identical to the original game card, stripped of copy-protection wrapper code but preserved without modification.
Games for the 3DS vary significantly in size, from a few megabytes to several gigabytes. The size of each game's ROM can depend on several factors, including the game's complexity, graphics, sound quality, and whether it's a single-player or multi-player experience.
