I recently got Megaman X3 for the Saturn (ok, it's called "Rockman" but it's the same thing.)

It plays great (a bit easier than X4 I believe) but it has borders on both sides, kind of like a TATE mode. Anyone know why?

I don't have the original SNES X3 game. I know that X2 and X3 (for the SNES) used the C4 chip for better transparency and 3-D effects, but I have no idea what sort of job the Saturn did duplicating these effects. It seems like a straight port would be difficult considering that the SNES used a special graphics chip built into the game.

How do they compare? Anyone?
