Famicom Mini is a series of classic Famicom games that were ported to the Game Boy Advance and the Japanese counterpart to the Classic NES Series. A couple of them were only released in Japan and were not developed by Nintendo, Mappy being one of them. The main difference between the original Famicom port is that the Famicom Mini version runs with much less lag due to better hardware.
