I was researching whether there's legal precedent making such uses legal, and ChatGPT pointed out that "Sony Corporation of America v. Universal City Studios, Inc.," where it was decided that developing a VCR where users can record Universal's content is legal.
Sega Enterprises Ltd. v. Accolade, Inc.: In this 1992 case, the court held that Accolade's reverse engineering of Sega's game console for the purpose of developing compatible games without licensing was a fair use.
Sony Computer Entertainment, Inc. v. Connectix Corporation: In 2000, the court ruled that Connectix's reverse engineering of the Sony PlayStation to create a compatible emulator (Virtual Game Station) was fair use.

I think this applies here as well. Curious how this will play out.
