【First Generation Game Boy Bros. Yellow DMG-S-YA】Tested and Working This listing is for the console only; no accessories are included. As shown in the images, the console has been tested and is working. Contrast adjustment and sound are good. (The game cartridge used for testing is not included.) It works correctly with both batteries and an AC adapter. The screen has fine scratches and some wear. There are also some minor stains and scratches overall. I have performed maintenance, cleaning, and parts replacement, but this is an old, used item. Please understand the above points before considering a purchase. Shipping will be via Yu-Yu Mercari Mail Yu-Packet Post. The console will be waterproofed, wrapped in bubble wrap, and shipped in an envelope.
