The Super SD System 3 (SSDS3) is a revolutionary device that allows for PC Engine CD and Turbografx CD playback from an SD card on read hardware. It also includes a circuit to allow for RGB output. Though the first hardware revision of the device had some problems with video noise, it seemed like they got everything right in the second revision. However, there is a small issue still extant on the first run of the second revision: the tantalum capacitor on the composite video line is backwards (this is being corrected in production going forward):
However, this isn’t an issue if you don’t use composite video, and even if you do, it’s not likely to cause many problems. Refer to this episode of the Retro Roundtable (46:50 mark) for an excellent and thorough explanation of the issue.
So this isn’t a critical issue, but I was already rewiring a SCART cable for the owner and it is a really simple fix, so I went ahead and did it.
If you’d like me to fix this for you, I can do it for $5, or for free with any other order/service.
