Multi system emulators focus on emulating many different systems under one program. They can be focused on a single company's systems because of the similarity of the systems, or may have systems from many different companies.
To be defined as "multi-system" an emulator has to emulate two or more distinct systems. For the purpose of this list, Addons (eg. Sega CD, 32x) are not counted as a separate system.
