Nintendo DS Lite White & Green ニンテンドーDSライト　白＆緑 All functions, including game startup, button operation, and the D-pad, are working perfectly. Regarding discoloration, it's not entirely absent, but I believe it's minimal. I've included photos showing the actual appearance of the LCD screen and gameplay from different angles, so please refer to them when considering your purchase. The item will be carefully packaged with bubble wrap and other protective materials, and will be made waterproof before shipping. *The game cartridges used for the photos are not included in the sale.
