An emulator. An emulator is a computer program that duplicates the function of another system. For example, MAME is an emulator application designed to recreate the hardware of arcade game systems in software.
Other than the emulator a ROM image, or simply ROM, of the game is required. The ROM is a computer file which contains a copy of the data from a read-only memory chip, often from a video game cartridge, a computer's firmware, or from an arcade game's main board.
Owning and distributing MAME itself is legal in the US, as it is merely an emulator. The situation regarding ROM images of games is less clear-cut as most arcade games are still covered by copyright.

Emulators are a software emulating another computer. For example, an NES emulator is a software that is ran on a desktop PC to look like the NES (Nintendo Entertainment System), whereas you can play NES titles (Cartridges emulated as ROMs) using your keyboard or a controller for the NES controller. However, emulators are not just for other computers. Technically, an emulator is a piece of software that allows foreign (different language or setup) hardware or software to interact with the current system. The NES example is a good one. An example with software is like installing windows software on linux. It cannot be done due to language conflicts. An emulator solves this problem.
Best Buy does not sell Sega Saturn emulators. Emulators are software programs that allow one computing system to behave like another, and they are typically available for download online. While you can't buy the emulation software itself at a major retailer like Best Buy, they do sell some retro gaming accessories that can be used with emulators, such as controllers.
If it is a game, certain emulators could run it. If it is a show, episodes can be downloaded and played with software such as VLC, MPC-HC or Windows Media Player.
