The problem is, you must reset the CIC for it to start working. If you don't, the CIC will get very hot! I dunno why this is, but it does. When working normally, the CIC does not get warm.
While messing with the CIC logger I was trying to make, I got an idea on another way to beat this system. When no cart is in the NES, the system isn't in reset the whole time. If we could disrupt the clock signal going to the Lock while the system is on, the lock won't be able to function and the NES will stay on. Ofcourse for this to work it would require messing the clock signal up enough to halt the MPU in the lock. But at the same time it can't damage the oscillator. Would this be possible?
That won't work. They use two separate inverters on the 74HCU04 to individually buffer CLK to each CIC.
I got it to work on the bread board pretty easily by just removing the clock signal wire. Anybody know a good way to stop the clock without damage? I have no problem with testing this on one of my nintendos, worst case scenario I have to remove the CIC altogether.
Just remove two CICs from two cartridges and use those... Though I am unclear if you can use the 6113 CICs back to back.
Speaking of this, I am kinda confused about why nintendo did this. The console *always* has a 3193 CIC in it (US console), while the carts have a 3193 (older) or 6113 (newer). I was wondering if the 6113 was a "key only" cost-reduced version or something... Even the very last versions of the front loader have the 3193 in it... So there must be some reason the 6113 is not usable as a lock.
