1. Backup your "main" save game file to a separate USB or Memory Unit (you will have 2 save files for ITSP, one is your "main" and the other is the "collectables" one).
2. Start a new game and get Concept #24. This will write to your "collectables" save file.
3. Restore back your "main" save file to your original storage device (most likely your hard drive).
That worked... now to find some people to help me get the marathon cheevo.
