You say that to edit a wrong chip i should replace it with a workable chip. The problem is I spent an hour making this complicated chip which has lots of working parts inside of it, and i don't remember how I made it, so I can't just make a new one.
Well, it's not a serious project. It made for "How does computer works" video series. But then his subs asked to add his program from his video to itch.io. That's why it happened. A lot of bugs appeared because of low usage of this game.
