I’ve been trying to use my old gameboy again, but it hasn’t been charging right. It can’t hold a charge and only can be played when connected to a charger, but I have to repeatedly turn it off and on to make it turn on.
Hi, Try replacing the battery in your GBA SP. Even rechargeable batteries have a life span. Here is a link to the Ifixit guide on how to replace the battery. Nintendo Game Boy Advance SP Battery Replacement. Here is a link to just one supplier of the battery. This is not a recommendation to use the supplier, it is just shown to give an idea of the cost of the battery. There may be other suppliers online. Just search for X77BN battery. https://www.amazon.co.uk/Rechargable-700… Hopefully this is of some help.
