The Perpetuum Planner github page has instructions on how to extract the images (and other resource files) from the Perpetuum.gbf file. I've used this as a basis for a couple of projects, including the hi-res island maps used by the Foom Scan1App (raw maps available here).
How up to date is that data though? I know a few of the extensions are wrong, which can be corrected, but what about the item/bot stats and such?
Edit: Nevermind, I think I misunderstood after reading the github, I was assuming you could get the data out of the Perpetuum planner as well. Can you? It seems to only give details for getting images out of the perpetuum.gbf
