I don't think that's right. There is absolutely no way that a SNES can, with just "a bit more memory", perform the same computation as a Silicon Graphics workstation of the time. That's like saying you could write a library's worth of books without a printing press if you just had a bit more ink for your pen. No, you couldn't. You would grow old and die long before completion, even if you wrote every second of every day of your entire life.
