Did you check the PR source code, the files lzg_compress.c and lzg_uncompress.c in the directory PR/src/lib/compression/?
If you did and don't understand certain things, you could try to contact one of the following people: Anke Balderer or Diego Essaya (dessaya AT fi.uba.ar), or maybe Enrique Calot or Tammo Jan Dijkemma.
You could even try to contact Jordan Mechner, because the original/real name of the algorithm he used may not be LZG; it could be a well-documented algorithm.
I haven't looked into it myself, these are just some pointers. What will POP1Studio do?

Technically the coder was Lance Groody. But if you need help understanding the algorithm I can help you. Anyways, if your tool is GPL you can just reuse my code without having to understand the algorithm.
