The Play-Yan is advertised as offering sixteen hours of MP3 playback and four hours of MPEG-4 playback on a fully charged Game Boy Advance SP. In addition to multimedia playback, the Play-Yan offers support for mini-games, which could be downloaded from Nintendo of Japan's website.

The new version is compatible with all the same systems, and it looks and works the same as the original, but there are a few noticeable differences. The Play-Yan Micro has the added functionality of MP4 and ASF playback, and it has an updated user interface and improved sound quality through its headphone port. Minigame support, however, was removed from the Play-Yan Micro. The Play-Yan Micro was only available through Nintendo of Japan's online store, and for an additional 1,000 yen, it came with a computer application on CD called "MediaStage Ver. 4.2 for Nintendo" for managing music and video files on a PC. Appearances in the other games The stick figure seen in the Play-Yan's interface also appears in the Japan-only GBA game Rhythm Tengoku, and its arcade version, in the rhythm game Night Walk. It was later used as a visualization in the Nintendo 3DS's Sound feature. The character also made cameo appearances in Rhythm Heaven and has reappeared in the Nintendo 3DS game Rhythm Heaven Megamix.
