If you obtain something from Jay, please write this guy a message: Shadow Moses
His project is already cancelled because of Konami.

Airam Hernández (Shadow Moses) changed his project and created a "museum" (download on his twitter account). It seems museums are acceptable. I have no idea what kind of license he obtained.
An alternative could be a "clone": Bloodstained: Ritual of the Night (a clone from VIPs), 20XX (Mega Man X clone), Freedom Planet (a modern Sonic the Hedgehog clone), ... A clone is legally salable and you don't need a license. Just don't be too obvious, if you want to avoid new problems.
