Famiclone

A Famiclone or Famicom clone is a type of clone hardware designed to replicate the workings of the Family Computer or Nintendo Entertainment System. The earliest type of clones were nearly one to one copies of the Famicom but later clones starting around the late 90s incorporated the hardware onto one chip, known as Nintendo-on-a-chip (NOAC). Most Famiclones originate in China, but many have been released worldwide.
