The SNES CD version from Nintendo and Sony is a real-life project but not released, and the NES CD is about fantasies under illegal substances.
By the time it became technically possible and economically feasible to release CD addons or full-fledged CD consoles, the 8-bit NES was no longer of interest to console developers, game developers, or the players themselves. Yes, we still love the NES and its games... but "If ifs and ans were pots and pans"
When Nintendo tried to cooperate with Sony, the initial idea was to release a CD addon to the SNES (not NES) and possibly a next-generation console with CD media instead of cartridges.
And when they couldn't come to an agreement (because of Nintendo, by the way), Sony took a chance and released their console Playstation. And they didn't lose.
During the same time period, there was many talks of the next Mario game, which the development team DEFINITELY REPEATEDLY stated would be 3D rather than 2D. So the NES is not at the checkout here anyway.
My main thought is:
By that time, everyone had already forgotten about the NES a long time ago at moment we talking about. That's why I wrote that the hack looks lackluster for such an unreleased console. Unfortunately, hack looks graphically weak even compared to later NES games although it is made on the SNES engine of the game, because of the chosen color solutions and perhaps the "talents" of the author, it looks not even like the SNES, but like the NES, which is what I WROTE ABOUT.
Moreover, there is NOTHING that could require a CD addon in this hack, even in a very remote approximation. You can't jump over your head without special tools that neither the NES nor the SNES had. In early console CD games, the media was mainly used for high-quality music, video installations, large sprites and animations - are we seeing any of this in this hack? Not at all.
