Rollback logging

[LeopoldFrilot]

I'm trying to track down and log exactly when a rollback happens and how many frames it had to rollback.

I see this error code: ERRORCODE_PREDICTION_THRESHOLD pop up from GGPORunner.RunFrame()

if (GGPO.SUCCEEDED(result)) {
    frameWatch.Start();
    ...
}
else {
    Debug.LogWarning($"WARNING: {GGPO.GetErrorCodeMessage(result)}");
}

Is this what signifies that a rollback has happened?
