This process is difficult and carries the risk of "bricking" (rendering unusable) the console. The alternative—downloading a pre-made keys.txt file from the internet—is widely considered copyright infringement, as it involves the unauthorized distribution of Nintendo’s proprietary cryptographic code. This dichotomy creates a scenario where the tool is legal, and the act of emulating games one owns is often defended as fair use, but the most common method of obtaining the necessary keys is illegal.
