It’s why the digital re-releases have been somewhat lackluster — the default music is fine, but not notable on its own.
Nintendo hasn't gone after the repos because they have a very solid fair use defense. They have, however, taken action against shared EXEs derived from that source code which DO contain the copyrighted SM64 assets. The fact that they went against that and not the code-only project shows they probably agree with this analysis.
Might be worth just directly asking Masaya Matsuura about this if you get stuck, he's fairly accessible via facebook (or at least he used to be).
Also, I've done no machine learning stuff at all, but wouldn't something like Vib Ribbon be absolutely ripe for reverse engineering via finding trends in the kinds of levels produced on the basis of the kind of music played fed into them?
I have first seen it like a week ago in this video essay https://youtu.be/1X6D39Cd34k where it seemed to have an adorable initial vibe, but after a minute of interaction, there is no more novelty and engaging content in it. What in this concept makes it worth our time, compared to AudioSurf, osu, PaRappa, or more recent, stunning Thumper?
Not only is it a cute game, but it's interesting technically too, the entire game fits in ram so that you can remove the game disk and pop in a music CD to generate a level.
They shelved it during dev for like 1.5 years or something until they figured out how to look 8 seconds ahead of the currently playing music on ps1.
It was originally being developed as part of an ad campaign for Mercedes A class, but then Mercedes dropped out and the game eventually became vib ribbon (cool origin story).
The vector graphics are pretty unique stylistically for ps1 as a platform, no other games really used that style.
Plus reverse engineering it would probably help people build better modified audio tracks to get the game to produce even better maps.
Those are just some of the reasons why other people might find it worth their time.
I think my only nitpick with it is that the generated levels could match the beat a little more/game seems like it could be a bit more difficult.
This reminds me of the demo disc i got with my ps1, it had a music visualizer that also loaded into memory and then let you swap out a disc.
"Ran ra ran, tanoshii na--otto!
Abunakatta!
Biburibon wa otokara umareta piisu ni awasete tadashii botan o osu geemu nan da!"
So weird to see this up from only 4 days ago. Can't wait to play it, I love the vibe of the game and the theme song/vibri are so cute!
