    Hey guys,

    Bit of a weird one here. Had a saturn hooked up with an RGC scart and would experience intermittent drops, but could never really put my finger on the issue. I recently got an RGB modded NTSC N64 and, by complete chance, seem to have been able to replicate the issue reliably. In goldeneye on the Dam level, there’s a red alarm box early in the stage, if I walk up to it and look at it, the OSSC loses sync. I then tried a number of other games and if I can get the majority of the output taken up by a red object, the OSSC loses sync again until it leaves the screen. The OSSC itself is losing sync, as the LED goes from green to red. The issue occurs regardless of the H-PLL Pre-Coast/Post-Coast and the output settings. I’m not particularly well-versed in the OSSC settings beyond hours scratching around on forums and the internet in general, so please excuse any entry-level errors. Has anyone experienced anything like this and would potentially be able to point me in the right direction?

    Can you try a console with 240p test suite on the entirely red screen?
