My childhood GameBoy Advance SP. Heavily worn and not tested with a cartridge, but it charges, holds battery well for its age (fully charged two weeks ago and still working), and the sound works. Buttons do not stick. As pictured, there are a few marks, including a dent to the top-right of the screen, along with further scuffs and marks — it has been heavily played. Sold with a heavy heart, but I highly doubt I will ever use it again.
