Nintendo entertainment system clones are hardware clones of the Nintendo Entertainment System and are rarely licensed. Nintendo has been cracking down on their production. Most of these consoles are manufactured in east Asia and are only sold in certain stores depending on their legality level. For example,a clone with pirated software built in is only sold at places like malls and flea markets. Ones that have original software built in are sold in places like dollar stores and pharmacies. Consoles that have no software built in and are intended to be a non-collector alternative to retro gamers are sold at used game stores.
