If its been used its pretty clapped out at this point. The glue on my gameboy lcd panel failed which required frequent regluing whenever that old dab of superglue would also eventually fail. I bet if I took it out of the drawer right now it would be loose again and need another dust off and glue job. The buttons also go. My gameboy color is sadly basically unplayable because the buttons aren't very responsive anymore. I'm sure that is coming for my ds as well. My switch joycons are already shot. None of my original game cube controllers really work anymore and the system itself has stopped reading disks (thankfully new oem controllers are still built for that for the japan competitive smash market at least).
