There's another reason why these games weren't ported to home consoles: hardware. The arcade hardware of the day was leagues more advanced than anything we had at home. Even ports like TMNT: Turtles in Time suffered massive downgrades to bring it to home releases.

I will say, though. The choice of porting to the Saturn is both ambitious and incredibly smart. The Saturn excelled in rendering sprite based games. It was also a nightmare to work with due to it's haphazard architecture. But it looks good so far! Hopefully this can get off the ground...
