[Proj3] Register $zero

[Jeremy Cowles]

I was just running halt.hex, and I noticed that it's writing to register
$r0. Is it safe to assume that $r0 is a writable register (unlike $zero) and
that we will have no constant zero register?

Thanks,
Jeremy

" 1) The zero register isn't special. $r0 is just a regular register like
$r1.
"

Doh!
Thanks
