Was there ever a revised shoop (after Erik Reckase abandoned the code) that works with the earlier MPEG2 flocks, like Flock 00198?

I have seen the newer Shoop project, but it doesn't work with pre-00224 flocks is my understanding.

I have over 20,500 (90+ GB) of the sheep from Flock 00198, and want to "shoop" them, but don't want to risk the original tool deleting any of them.

BTW, I have the GNM files for each sheep from previous runs of the old Shoop tool, which might be useful to Spot as archive material.
