Hyperstone Heist is a weird case. It's not exactly another port of Turtles in Time, but it uses a large amount of its assets, and ultimately just makes things a bit confusing. I don't exactly know the reason for this. I'm sure Turtles in Time could have been ported over to the Genesis with very minimal sacrifices, though I'm no expert on the hardware.

Whatever the reason may be, the Genesis got this instead, which is basically the same but with five different, longer levels instead of the original's ten. It also looks a bit murkier as a whole and has an option to make the turtles an uglier shade of green.

This one is damn solid on its own, but really it just makes me wish I was playing its SNES counterpart. I have no idea about the arcade original, I feel like there's a good chance this is an improvement over that if Konami's other arcade beatemups are anything to go by.
