Just for the record, I was able to figure this out tonight, and they look great once I adjusted my settings. So the sprites are 252x48, but only the inner-half is used. I split them into 4, so it was 63x48, and then took the inner two sprites out of every 4. For example, [_, x, x, _] is one frame, and 3frames are [_, x, x, _, _, x, x, _, _, x, x, _].
