    • CAVE PGM conversion audio quality

      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.

    • Very likely the motherboard. Have you recapped it?

      I have all three versions of DPP:DOJ and I'd say the cart sounds the same as the PCB. PGM2 sounds better than both, but not a huge difference (and that won't help with Ketsui or Espgaluda anyway).
      On the hunt for: Dinoking, Mushiking, Love & Berry, Egret 29, Grand Am Q25, Capcom New Concept 2, and Naomi guncabs.
    • The conversions sounds a bit noisy for me too: I lowered the volume of the motherboard and it's better but replacing the caps might be a good idea. Anyone has a list ? ( the day after I've made an order @ greatplains electronic of course)

      Now speaking of that motherboard, @GC8TECH posted a picture of his pre modded boards and are the caps related to the sound just the 3 ones pointed?

      and is that sound mod just to output 2 RCA for "simili stereo" or is that preamped sound coming out ? if it's not, is there a way to get it before going to the amp?

      No.. its not just those 3. You need to do all the ones below it as well. The 7 below it in an almost straight line need to be replaced as well.....

      The Stereo out comes from the Left and Right Channel output from the DAC.
