The Play-Yan (trademarked PLAY-YAN) is a media player for the Nintendo DS and Game Boy Advance. It uses SD flash memory to play MP3 audio files and H.264/MPEG-4 AVC video files. It can also play 13 bonus mini-games, all of which are available freely on the Nintendo website in Japan. It is designed for the Game Boy Advance SP and also compatible with the Game Boy Micro. Due to its power requirement, use with an original Game Boy Advance system is not recommended. Sales of the Play-Yan were discontinued on September 11, 2005. An updated version, the Play-Yan Micro (trademarked PLAY-YAN micro), known as the Nintendo MP3 Player in Europe, was released two days later alongside the similarly branded Game Boy Micro, with features such as MP4 and ASF support built directly into the hardware. Play-Yan Garage Games are not supported in the Play-Yan Micro.
