Simple, PRP test savefiles tack on an additional version of the last 4 items in the 'current Mlucas file format' list - full-length residue byte-array (this one holding the accumulated Gerbicz checkproduct) and the 3 associated checksums totaling a further 18 bytes. Thus, where an LL-savefile read reads one such residue+checksum data quartet, 3 bytes for FFT-length-in-Kdoubles which the code was using at time of savefile write (*note* your quote in post #2 needs to change that from 4 to 3 bytes), 8 bytes for circular-shift to be applied to the (shift-removed) savefile residue, a PRP-savefile read follows those reads with another read of a residue+checksum data quartet.
