OK , I might have done it+1 TO IT
I edited this archive, but im no developer nor a game creator and i only have marginal knoledge of coding.
All i did was changing the unlocked "false" to "true", and i noticed a bunch of nulls, so I changed them to 1
anyway, the gallery seems to be unlocked. the location of the archive is ...AppData\Roaming\Pervert Action Timelapse
please back up your original or edit it yourself
and if someone with actual coding knowledge could do a better job that would be amazing
also the version is the one i dowloaded from the main page, i'm sure that's important
