I understand, but the Saturn is one big censored flip-flop system, that breifly took the place of the PCE, along with the Playstation. The Saturn is a 3d system, with two proccessors. The PCE can do every single 2d feet the Saturn gave to us, if they only tried. Look at the N64 and Resident Evil 2.
With a 2d game, each proccessor does a seperate job. With the PCE you have one 8-bit proccessor doing most of the work, with a small amount of memory.
However honestly I was into Saturn games, but I got sick of it. I wanted less 3d and more 2d. Then when I discovered that most of the Saturn games were on the PCE, I said so long Nights, and hello Deneb.
