Hey, downgrade the ESP8266 Arduino core to a version < 3.

If you aren't sure which board you have, select "LOLIN(WEMOS) D1 R2 & mini".

Can you resolder your N64 mod to use sync on luma? That should work better. Csync often requires specific attenuation (resistors of the right sizes). Luma sync is less tricky.

I think there's some kind of problem, possibly on the GBS board itself. Do other consoles work fine?

Hm, tough luck there, but a learning experience for sure :) Let me recommend the HD Retrovision Genesis cable with the various console adapters. This is ideal in quality and...

Hey, yours is a very clean log, where I don't see any issues. Your video clearly shows sync losses though.

Yea, it's permanently unstable in these logs, while your video shows it would work otherwise. This is a failure of one of the sync parameters, like sync windows, etc. I...

On your ESP8266 devkit, you need a power input and a good ground connection. That is enough to make it work. Since you get some logs from the devkit, I...

Noise gets into the system, and due to it trying to synchronize source and output, the noise becomes a visible pattern like this. It can be hard to even find...

Yep, that often helps.
