CAVE PGM conversion audio quality

[Arcade-Projects]

I have some of the conversion carts for CAVE games, finally getting around to testing things. Now that I have legit and PGM ESPGaluda side-by-side, the only difference I really noticed is that audio on the PGM cart is pretty uh, noisy. It doesn't sound as good. Is that something with the conversion or something with the motherboard?

I have one or two legit carts I haven't tried yet, that's the next thing I'd do. From a collector standpoint I'd prefer to keep the legit boards but from a business standpoint I'd be better with the PGM carts. Audio quality won't really matter in an active environment, but I'd like to get it fixed if I'm playing at home.
