I have a CPS-1 with bad sound.
I say "bad sound" instead of "no sound", because it does play some sounds nice and clear.
It does not play any music.
The A PCB is the 89626A-4 12 mhz DASH model.
The B PCB is a Daimakaimura (Japanese Ghouls n Ghosts) reproduction.
In the test menu, it will play some of the sound effects, but none of the music.
No sound is made when inserting a credit.
When the opening scene plays out (after pressing start), only 2 sounds are played (no music), when the 2 characters are cut down by the demon.
When the game begins, 1 sound is made. That sound kind of echoes and then there is nothing but silence until the power is cycled.
I have created a video that demonstrates the issues I am describing: https://youtu.be/f1tHsWFhHc0
Does anyone know what may cause this issue?
My searches have revealed it could be the z80 but I do not want to just start replacing parts (although that may be required).
Thanks for your time.
