Do you know what battery type is needed for older games like Pokémon Green?
There are no telling marks and it's notably smaller than the battery used for others I've fixed like Crystal or Red. I want to be sure I'm using the right replacement.
The older cartridges should use the CR2025 the gameboy advanced cartridges sometimes use the CR1616, I buy my batteries off of amazon with the soldering tabs on them
When you change a Gameboy Cartridge battery, do you lose the currunt game save , THX
Yes, anytime power is lost to the volatile memory the save is wiped.
The purpose of the battery in the cartridge is to retain stored memory such as saved games so if you remove the battery for replacement or the battery dies it will delete the saved game. Sucks really hope this helps
