I've tried using Daemon's Tools to work with the .bin files, but problems still come up. I'm thinking of just going through with the install as normal except when the error messages for the .GPK files pop up, I'll press Continue instead of Abort or Retry. Then, I'll keep track of which files the error message came up for and try and search for them online. I know this plan sounds stupid, but since I had trouble with your suggestion, it's the simplest idea I could think of.
