I want to know the answer to the following question:
What did the Famicom sorely lack?
All the background I'm provided with is that "Tinkerers at home in later years discovered that disassembling the NES and cutting the fourth pin of the lockout chip would change the chip’s mode of operation from "lock" to "key", removing all effects and greatly improving the console’s ability to play legal games, as well as bootlegs and converted imports.". Is that enough to answer the question?
