I was using the simulation and i found that you cannot save outputs in a gated latch kind of style. also there are glitches where if there are 2 inputs going into one output and one is on while the other is off than it will turn on and off a lot. Great sim though. i'm learning basic computer science with it

When you have conflicting data going to a pin, it will flicker. This is intentional to let you know something is wrong. If you want either input to send data to the pin, use an OR gate to combine them, and send the output to the pin.

2 NOR gates can be used to make a simple Set-Reset Latch.

Sebastian has a tutorial on memory!

Hope you get these solved! Good luck!
