Forgot to mention that in order to decompress compressed GR2 files you will need Granny Viewer v2.8.33.0 installed on your computer (as that's the version I RE'd to find where to install my hooks at). The app will spawn the Granny Viewer when it needs to decompress a GR2 file. You will need to select the same file in Granny Viewer so that it loads it and decompresses it (and while decompressing it will spit out the decompressed sections a la my injected code into it
). My app then takes these decompressed sections and builds a new GR2 file out of them
