|Marble Madness (prototype)
A prototype of the unreleased Turbografx-16 port of Marble madness
Game was in posession by the former Tengen developer Jun Amanai, who posted a video on youtube showing off some of the gameplay. The prototype is, as of 7-24-2017, being sold by the developer on savejapan.com/shop for $6,800, along with a couple of other unreleased games. The game itself seems to be pretty far along, but there's still a few things that just don't work, such as the black marble's AI.
