There are three revisions of the 1CHIP motherboard: SNS-CPU-1CHIP-01, SNS-CPU-1CHIP-02 and SNS-CPU-1CHIP-03. The “03” revision does not have csync run to the multi-out. You can use these consoles without a modification, simply by using an RGB SCART cable that gets sync from luma. I’ve been able to restore csync on these consoles by using a simple jumper wire, however that doesn’t seem to be the best solution, as it’s missing circuitry found in the other 1CHIP revisions: http://www.retrorgb.com/snescsync...
If you have a 1CHIP-03, you’ll want to consider using a sync-on-luma cable, restoring the entire circuit on the motherboard, or using an RGB bypass board that includes the full csync circuit.
