Copy the "vpc data" folder and the file "vp save.vpx" into this new folder. Do this just before you play a Boss. Every time you defeat a new CPU player, quit the game and backup the "vpc data" folder and "vp save.vpx" file again, letting Windows overwrite the older files. If you lose to the CPU, just copy the contents of your "save backup" folder back into the main "virtual pool 3" folder, and let Windows overwrite the files.
