The side portions of the top screen of my Nintendo DS turned dark and I have spare replacement screen. Anyone know anywhere I can send them for the replacement as removal and soldering required? Thanks

Best bet to try Shopee or Lazada but the prices for new units are inflated. I rarely ran into any game shop now selling new 3DS consoles. Most are modded versions. A number of 3DS games were ported to Switch actually so give it some time and you would have the same library in Switch eventually - the latest I remember is the Katrielle "Kat" Layton game (coming soon).
