Fix the simd issue at least for Wipeout

I haven't tested any other cases yet, short on time.  It turns out dirty was the cause.

Better would be to find the culprit.  I thought I caught everything with the simpleregs...

Would appreciate any testing.

Oh and also this, not sure how much trouble this might've caused, but it didn't seem to affect Wipeout.  Dumb typo...
