Many games are "orphaned" (abandonware), but you should only download ROMs for games you physically own the arcade PCB for, or those released into the public domain.

In the sprawling digital archives of the internet, few artifacts carry as much mythic weight as the “MAME Full Set.” For the uninitiated, MAME (Multiple Arcade Machine Emulator) is a decades-spanning software project designed to preserve the hardware of arcade cabinets, from Pong to 1990s polygonal fighters. A “Full Set” is precisely what it sounds like: a complete, uncompressed collection of every game, BIOS, and device that MAME can run. At over 70 gigabytes and containing tens of thousands of ROMs, it is the ultimate act of digital hoarding. While the allure of possessing a complete arcade history is seductive, downloading a full set is ultimately a counterproductive exercise in curation, a storage nightmare, and a profound misunderstanding of what makes retro gaming meaningful.

First and foremost, the sheer volume of a full set is its own worst enemy. Of the nearly 40,000 unique ROMs in a complete MAME 0.200 set, the overwhelming majority are unplayable to the average user. A significant percentage are “non-working” dumps—games that MAME can boot to a title screen but cannot run due to imperfect emulation of custom protection chips or obscure graphics hardware. Thousands more are bootlegs, hardware test programs, or mahjong and gambling titles that never left Japan. Buried within the zip files are also dozens of identical clones and regional variants. The pursuit of a “perfect set” forces the user to wade through an ocean of digital detritus to find the few hundred genuine classics— Street Fighter II , Pac-Man , Metal Slug —that they actually want to play. It is akin to buying an entire library to read one book.
