Ok, so the famicom adapter has a lockout chip, the NES system has a lockout chip, am I able to use the famicom adapters lockout chip to replace the original NES one? I know, I don't know need it lol.. but I'm trying to do something and I'd previously removed the 4th pin and it came OUT of the IC so I can't just solder on a workaround. I'm curious if I pull the famicom adapters lockout IC that if it'll work in the NES system under some logic that perhaps the pinout is the same and has the same functionality...? Not completely sure if it does. Both chips read 3193 but the NES is 3193A and the famicom adapter is just 3193, it makes me wonder if the functionality is slightly off from what the NES system would accept as a viable replacement. Any thoughts? Thanks guys.
