This one is weird. Its some type of checksum calculator, seemingly for the best time trial records. But the number of bytes it operates over is odd. It calculates a checksum for 51 bytes in 17 byte chunks, but that doesn't line up with anything in the save data cleanly. At that byte count it would get the 48 bytes for the records plus 3 of the unknown bytes.

But only unknown bytes 7 and 8 ever get set, so why the extra 3, and why in chunks of 17?
