I'm a bit confused - is it actually clean room if they basically checked the disassembled compiled binary and wrote or generated (the actual project page mentions mips_to_c) the C code that compiles into 100% exact same binary? I was under the impression that "clean room" meant reimplementations that were made by only looking at the results (in this case - how the game actually plays), not at the original binaries.
For video games the binary is the covered work, not its disassembly. And disassembly is covered by the DMCA and explicitly allowed for this type of purpose, so that’s not illegal at least. I can see the argument if the clean agent is just operating off the disassembly and a different person is evaluating success.
After all, how does one communicate the goal of a “traditional” source code clean room operation? Well someone has to disassemble the target functionality into a natural language description of the algorithm and communicate the requirements and expected outcomes, the functions if you will, to the agents as well as check success. Why does using a computer to aid that process make things questionable?
IMO the whole notion of a clean room for copyright purposes is weird across the board. Not just when punks do it.
as long as no one is trying to make money / sell ads / patreon lock the results, they should be fine; it's probably difficult for lawyers to claim monetary damages if no one is making money
Of course there are other benefits too that some use for playing the originals as they were. Some just want to more easily read through the games code to figure out how it works, hunt for new glitches, figure out why that odd thing in a speedrun happens. Others want to mine for cut/missing content.
I personally hope https://zeldaret.github.io/tww/ gets completed this decade. Nintendo has at least made an actual remake of this game, adding a certain level of the improvements and enhancements, but there are still more which would be nice (more than 30 FPS anyone?) and I can only imagine what kinds of customizations would be made feasible.
I've been waiting and waiting for Majora's Mask to catch up. I got the recompilation and all, but no textures and other bells and whistles YET.
Glad their Switch legislation hasn't killed this yet.
A significant portion of games from that era are probably effectively lost at this point. The current system can't be allowed to continue.
The binary is readable so what is it wrong to say oh i have a code that produces the same binary ?
Especially if you dont monetize
More often the comments are less interested in "what is the actual legality" and more "how will Nintendo use the legal system to take it down". Often Nintendo is probably on the "correct" side (as in the law agrees this is the currently intended interpretation) but even more often people just don't want to go to years of court about their hobby fan project.
