    Tested a few things with the replica circuit and noticed that adding a 500ohm series resistor after the buffer significantly narrowed down the TTL hsync range where Pro could reliably lock. I don’t know if Splitfire has a resistor like that on board, but in that case one workaround could be replacing it with 0ohm resistor (or maybe 100ohm to make it more safe with cables connecting sync line directly to SCART) to make it more compatible with Pro. I’ll be also trying different ADC settings to see if it can be made less sensitive to sync characteristics even though hysteresis and glitch filtering should be already enabled.
