1. Game Rom Cartridge(B Board): This cartridge is in working condition tested as you can see in the pictures.

I have not replaced the built-in battery.

The cartridge of CPS 2 does not work when the battery is empty.

And I do not know when the battery will be empty.

It worked normally when I tested it, but I do not know if the cartridge will work correctly when it arrives at you.

Please purchase only those who have the technology to replace batteries.
