the ad says, "consistent Super Nintendo / Nintendo 64 / Nintendo Gamecube" against it by the cable does not seem to agree, the colors are pale and lose greatly in detail. I can not allow myself to judge its effectiveness when connected to a SNES or Gamecube but I absolutely do not recommend it for use with a Nintendo 64. it is increasingly difficult to find shops that know what they sell and the seller there simply makes the task more difficult.
