Okay, that makes sense.

I don't know how to do that right now, but that's why I'm a Computer
Engineering major.

You're right.  Also, something else you could do with a Dreamcast, arrange
them in a cluster, like 3 or 4 of them could overpower a PS2, but it would
be next to impossible to provide comparable benchmarks.  If you couldn't
cluster them, it's a fun thing to think about.
