Is this legal? I know decompiling is legal in some areas for specific reasons. But I don't think that you can open source the result of that decompilation. You end up with an artifact based on something you don't have the rights to relicense.

Well, its not legal obviously to decompile and share the code online. But its just a matter of "will they care" and the answer is most likely NO. Just like SM64, it is open sourced on GitHub but they never got any complain from Nintendo asking to shut down anything.

Woooo! This was a simple but great game, and the music was just GREAT. Also, you could pop open the PS1 CD reader, and put whatever Audio CD you had around, so you could play with custom music that, more or less, was followed by the game levels.

The custom music wasn’t followed the game levels — the game was designed for you to swap in your own CD, and the levels would be generated off of that music.

It’s why the digital re-releases have been somewhat lackluster — the default music is fine, but not notable on its own.

Thanks to everyone that got interested by the repo. Even if we left the project on the side we may be able to work on it. Unfortunately, it is REALLY hard to get this done as we are a really small team. And we lack motivation and knowedges as most of us never did any decompilation in the past, me included.

Whoa. This blew up! I’m working on a vibribbon like game and was curious about some of the internal workings and found your repo. I am interested in helping. I’ll come hang in your discord this weekend and see what I can help with.

Now's the time for open door and start it! Don't look back so nothing to lose / Party just goes on!!

https://github.com/phoboslab/wipeout-rewrite hasn't gotten any flack and it's rewritten from the PC leak.

The PS3 PSN version still works with CDs at least. Kinda better because you don't need to swap discs. PS4/PS5 (and obviously Vita) can't read CDs.

Which was fascinating, technically speaking, because the PlayStation was never intended to be played without a game disc in the drive. Vib Ribbon's graphics are so brutally simple because the entire game has to fit in 2 megabytes of RAM when you remove the disc. It loads it on boot and then never touches the data track again.
