Howto open a MVS cardridge

My cardridge of FATALFURY 3 has lost his sounds, in the beginning after a couple of restarts the sound was back on, but now the
sound is gone.
I think that some contacts (of "wire" ?)is lose.
Does anyone know how to open a MVS cardridge
without dammaging the cassette?

Thanks in Advance,

?Umm, MVS carts have regular screws, so you you should have no problem removing them. You can try using eraser to clean your contact as well.

Unscrew the 4 screws, pull apart the plastic case. Make note of the orientation of the 2 boards so you do not swap them when they go back in/

Thats it. Much easier to open a MVS cart than a Home cart.

Also, there should not be any wires inside, you probably just need to clean the contacts as suggested above.
