Reader Rabbit .GRP files

Post by Puterboy1 »

Has anyone looked at extracting/unpacking these?: https://ia902900.us.archive.org/isoview ... oddler.iso

This should work. Sorry for the messy output names. Some files have one or two more GRP files within them so you can rerun the script on those.

Actually, I think this is what I want extracted: https://archive.org/download/RrToddler/ ... DATA_CD.DF

Those files were for a ClueFinders demo.

Each file has a 16 bytes header and then a "COMP" that may or may not be related to compression.
I didn't check the compression (which can be anything) so now you can at least dump the files.
