For parts Vampire Hunter and Vampire Savior CAPCOM CPS2 Cartridge set-g0513-

Both cartridges do not work because of the runout of the inner batteries. 

1. Game Rom Cartridge(B Board): This cartridge is not 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.
