I've been fixing this issue for ages on Wonderswans. The underside of the button is just a black conductive carbon pad. These tend to get dirty and wear out over time, but can be easily fixed by using a Nickel Conductive Pen to re-coat the pad in a new conductive layer. It's a super quick and cheap fix and and as long as you let the layer dry properly before playing, will last for many years.

Considering that at best they are 16y/o battery, they are all dead even "brand new"/"unopened" one..
Haven't found a clean way to open they. I fear that opening them would be a destructive action.
The best would be to make a new shell using 3d printing that use the same type of battery ("gumstick" one: https://www.amazon.com/Gumstick-1400-mAh-NiMH-Battery/dp/B003F9UWTM )
