This is a PlayYan Micro for Game Boy Advance software. This is a cartridge-only listing. I believe the cartridge is in good condition with no noticeable scratches or stains. (There are small scratches on the back from inserting and removing the cartridge.) I have confirmed that it works and that the music on the SD card plays normally. I will include the SD card I used for testing. *The PlayYan Micro only recognizes SD cards up to 1GB, and it may be difficult to find one that size as of 2026.*
