A complete set—including arcade ROMs, CHD (hard drive) images, and software lists for home consoles—now spans several terabytes of data.
The size of a MAME Full Set ROMs can vary depending on the version of MAME and the number of games included. However, a complete set of MAME ROMs can be quite large, often exceeding 100 GB.

While we cannot link directly to ROM download sites due to the nature of the content, full sets are commonly distributed via BitTorrent, Usenet, or specialized archival sites like the Internet Archive.
