And surprise surprise -- it looks a lot like F-Zero.
Some background for the youngsters in the house: when F-Zero first came out on the Super Nintendo it was considered the poster child for 'Mode 7', a graphics technique that allowed rotation and scaling. It made for some seriously mind-blowing visuals at the time. It was a major selling point for the Super Nintendo back then.
Therefore a game like F-Zero, which made full use of Mode 7, would normally have been considered impossible to recreate on the SEGA Mega Drive.

Above is a video of what F-Zero may have looked like had it been running on SEGA Mega Drive hardware. Put together by gasega68k, you can play it right now using Mega Drive/Genesis emulators. I'm actually amazed at how smoothly the game runs.
For reference, here is the game running on the SNES.
So yeah, it still looks a lot better on the Super Nintendo, but that doesn't take away from how cool this project is.
Maybe in 20 years time we can get a Metal Gear Solid 4 port on the Xbox 360?
