Just wanted to say, installed this board in my SNES (SNS-CPU-GPM-02).
Previously had tried the following:
SNES -> CSYNC SCART -> OSSC -> Sony X900E -- video with garbled audio, frequent video drop out
SNES -> CSYNC SCART -> OSSC -> Sony STRDN1080 -> Sony X900E -- no video or audio
With dejitter board installed:
SNES -> CSYNC SCART -> OSSC -> Sony X900E -- video and audio both working, video drops sporadically and frequently, maybe every 10-60 secs
SNES -> CSYNC SCART -> OSSC -> Sony STRDN1080 -> Sony X900E -- same results as without the AV receiver in the chain
So there's definitely an improvement, but the X900E still appears to be a really fickle TV -- playing with the settings on the OSSC showed some promise and could make the video drop outs more or less frequent, so there may be some combination of settings that stabilizes this. When I have more time I'm going to dig into this.
I've got a second board and I'm waiting to install this in a NES-001 with NESRGB -- has anyone done this and have any instructions or guidance?
Is this problem strictly with the RGB signal from the SNES?
I have a Sony 4K TV of roughly the same vintage as the one in the above reply (X720E). It seems to handle 240p decently (as 480i, but with proper transparency, flashing images, even resolution switches on PS1 on PS2 like Chrono Chross) over the YPbPr port directly. With RGB/YPbPr cables like RGC or HDRetro's connected to a Sega 240p console (Genesis Model 1, Saturn Model 1), no issues with what it displays.
As for the SNES, I have been mostly using S-Video transcoded to YPbPr (now using Koryuu, was using RetroTink 2X > Cheap HDMI to Component converted Mike Chi demo'd in a video), which as far as I know is still 240p (OSSC says so). Direct feed of that to the TV has no issues.
In OSSC I can go all the way up to 5X, whether I'm going through my Blackbird 4K 5x1 Presentation Switch or directly into an HDMI port in the TV using the transcoded S-Video.
However, with the HD Retrovision cables I have some weirdness:
Direct feed into the Component port results in repeated "blinking" of the image, like it repeatedly drops sync.
Connecting it to a RetroTink, directly into an HDMI port results in stable 480p.
Ditto with the OSSC, albeit at 2X.
The only way to get OSSC above that is to go through the Blackbird.
Only thing I can come up with is that it's because of the RGB signal, even though that's not an issue with other 240p sources, even using HDRetro cables.
