This type of hardware clone, popular in North America and western Europe, is designed to hold all the console's hardware in the shape of a regular game console controller, usually the Nintendo 64's. Also known as "NES-on-a-chip" due to their extremely miniaturized hardware (relative to the original NES), these controllers usually shun or at least downplay a game cartridge interface in favor of storing games directly in internal memory chips. These Famiclones can often run on battery as well as AC power, making them popular for portable usage. These clones have become especially popular in the USA thanks to the new "TV-Games" fad of selling legitimately emulated classic arcade games in a traditional-looking controller. (Atari games are especially common.) Controller clones can usually be found in places like flea markets, mall kiosks, or independent toy stores, and most people who sell and buy them are unaware or don't care that they are in fact illegally made. In Brazil this type of console is commercialized with the name "GunBoy".
