Dreamcast – The Dreamcast’s unusual range of signals often causes problems for those of us wanting to integrate the console into our setup. With the OSSC, you can connect the Dreamcast to the SCART input or the VGA input and use both 15khz or 31khz signals without any issues. Theoretically, connecting via SCART should give better results since then you have all the benefits of the low pass filter, though in practise there didn’t seem to be a huge difference.
At 31khz the image is perfect as expected. Checking in the 240p suite showed a perfect result with the linearity test, showing that the image was not incorrectly squashed at all. My TV manages to slightly overscan 480p content, but since only a couple of rows of pixels are lost, I’ll take that over a squashed aspect ratio any day.
At 15khz the Dreamcast was perfect too, exhibiting a wonderful, stable noise-free image without any need to perform adjustments
