Alrighty, I just skipped through it myself to get to the good stuff. Fully unlocked gallery save here! Good thing everything was fairly straight forward...
Unpack the 'system' file in your local user folder:
AppData\LocalLow\DefaultCompany\ChardonnayRomancia\Utage\SaveChardonnayRomancia
There is one gallery item I could not unlock. Anybody know what that is and how to fix that?
According to my conclusion after datamining there seems to be a legit gap in the gallery and the dev forgot to fix it.
