How about a faster version using a temporary cheat? Check first and last byte of first argument for key A, fail if not true; check first argument for crossing 2K boundary, fail if true; check first and last byte of second argument for key B, fail if not true; check second argument for crossing 2K boundary, fail if true; save current key, go to key 0, move the bytes, go back to original key; end.
