Every single zip file contains absolutely all files needed to run that specific version.
: Arcade games rarely consist of a single chip. A complete MAME ROM is typically a compressed archive (such as a .zip or .7z file) containing multiple data dumps from the game's sound chips, graphics processors, and main CPU. index of mame roms
Are the files organized by popularity, genre, or manufacturer? Organizing Your Collection:
Unlike console emulators (such as Super Nintendo or Sega Genesis), where one file equals one game, MAME emulation is highly complex. Arcade machines were built using distinct, proprietary hardware configurations.
The MAME project itself exists in a state of careful separation: the MAME emulator software is legal and open-source. The ROMs it runs are not distributed with the emulator. The project’s license explicitly forbids distributing MAME with ROM images, as that would violate copyright law. Therefore, users seeking an “index of MAME ROMs” are operating in a space that, while widely practiced, exists outside of legal copyright frameworks unless the ROMs are specifically released as freeware or the user owns the original arcade hardware.

Games like Killer Instinct , Primal Rage , or Dragon’s Lair require both a standard microchip ROM zip file (to boot the motherboard) and a corresponding .chd file (which acts as an image of the hard drive or disc).
In the context of modern emulation, a "ROM" does not refer to a single file. Instead, a MAME ROM is a containing multiple files. These files are direct binary dumps from the physical integrated circuits on an arcade machine's printed circuit board (PCB). Inside a MAME ROM Archive
