-5v pin jamma harness in my Blast city?

[pcornejo]

Hello, I noticed that my blast city jamma harness has not -5v pin because the blast city powe suply has no -5v output

Cretain games like blood bros uses -5v for sound, the question is how could I add -5v to my blast city? Do I have to change the power suply? Anyone has the same issue?

THANKS
