Just remember, before all of this we were for the most part dealing with versions of the games like thishttps://www.youtube.com/watch?v=FhQUfTyYEMc
What MAME is doing with these high resolution artworks and svgs is leagues ahead.
Well I don't think we want to disregard MADrigal who lead the way... but it's certainly surpassed it (in MAMEdev's eyes at least) with accurate emulation, not reverse-engineered gameplay.
I don't think he did all the games tho, I don't see videos of a Vermin from him at least (which is why I didn't post one of his in this instance, I did look) and even then a lot of his work is fairly low resolution.
They were nice tributes to the games, unofficial ports, but very much not the original code.
There's a fair chance that MAME is going to have full emulation of all of these within the next year or two, and that is amazing to me (and like Moogly, I really do hope Nintendo find a way to use our BSD licensed code for something official - a complete, fully emulated G&W anniversary collection would be a worthy addition to any console library)
