    Yes, TR1/TR2 are the pass-through amp transistors for the Sega CD.
    They pass the YM3438+PSG+32X through to the Sega CD.
    What this means is, if you remove these transistors only Sega CD PCM and...

    Recapping that VA2.3 won't fix those kinds of problems.
    Instead, try adding an 18pF capacitor to C13 and see of that helps any.
    Some VA2.3s with 315-5786 ASICs need an 18pF cap there (it's a...

    Made in Indonesia, serial # AD42005043.
    315-5786 ASIC. KA2195D encoder, big surprise. (At least they give way to CXA1645M's with comparatively little effort.)

    This might win the Captain Obvious award, but... you've made sure your cabling is good and the connectors on both the console/S-video jack and the cable are clean, right?

    I wish I had a working one to trade to you.
    But I did chip in my two cents on that thread you started about trying to fix your cart. After OCRing the datasheet and running it through Google...

    The transistor is a PST529F, that's a bit different from the nebulous 'PST529' that that eBay auction claimed the USSR-made part replaced. In fact there *is* no 'PST529', it's PST529C/D/E/F/G/etc,...

    Scammers will try to ensure you get so fed up you'll just let them get away with highway robbery.

    Not sure what the actual term for the functions I was talking about is, I've heard FM emulators referred to as cores back in the dark ages of emulation. Guess it kind of stuck.

    I thought we all left all the '____tard' baloney behind when we left high school.

    As for me? I just enjoy playing games on real H/W. It's just part of the experience for me, not necessarily...

    But wasn't there that issue with the erratic Total Level values? Or is that fixable outside of the driver?
    Actually I'm a bit curious: was this driver used in any other games other than this...

    I'm really liking the improvements made to this unreleased game so far.
    Any chance you can simply rip that faulty sound driver out and replace it with something like GEMS?
  17. Sega left off a crucial resistor that was needed...

    Sega left off a crucial resistor that was needed to prevent excessive pixellation. In the schematics of the 32X's technical manual, this resistor (R48) was listed but marked 'DO NOT USE'. Putting a...
  18. Tech Rant: Fix the NTSC VA0 32X's fugly composite video

    Myth: The 32X cleans up composite video.
    Reality: The 32X makes the composite video, regardless of encoder that may be present in the system, look little better than a KA2195D. It's dark, blurry,...

    One conclusion I can take away from this, is when programming for the 32X *always* try to buffer your stuff in RAM, avoid thrashing the ROM/cartridge space.
    Also Kega Fusion's 32X timing needs some...

    I don't notice any such glitches through composite video on my CXA1645M fitted VA2.3 Model 2 Genesis on Streets of Rage 2.

    2V is required for the /SRES line to work properly. On the VA0~1.8 the encoder's regulator provides this voltage, but the CXA2075 doesn't provide an external regulator.

    These are two reasons why I...
