This Sega Super 64X accessory for the Sega Saturn has by far the best version of Sega Rally Championship other than the arcade.

You still need the CD version for the Saturn along with the SRC 64X cartridge.

Improvements over the original Saturn game include higher definition graphics at 640x480 px, 60 fps over the original Saturn 30fps and much better textures. Loading times are much shorter too.

I made this mockup prototype Sega 64X a while ago and I've since wanted to make this video

Needless to say this is just an illusion, but would have been great to have a 1:1 port of the arcade on the Saturn. whatever addon was required

Thanks for watching!
