I recently got a hold of a Square-1 puzzle and have been trying to
solve it. I can get to the point where it's done, but two edges on
one side are swapped. How do I swap them back? Is this a parity
problem? Every move I have that swaps edges does TWO pairs are a
time, so I can't get there with what I have. Or can I?

I'm not familiar with Square-1...but if, as seems lkely, it's a square
that you have to get into some arrangement, then consider turning the
whole puzzle 90 or 180 degrees and trying again; that may introduce an
odd permutation and thus make a solution possible. Or depending on the
definition of "solved" - as I say, I don't know the puzzle - maybe go
for a mirror-reflected state.
