I just compared some FAKKU games on GOG with the uncensor files and noticed those uncensor files already exist on GOG as exact same copies, meaning the GOG version already has the uncensor files, and VNDB is wrong. Jesus what a mess.
Hi, just added you (did not realized that you meant GOG and could not find any option to add afriend on itch :D)
At least thea re korrekt with the Kirakira series. I downloaded the patches and opened them directly with an asset viewer. Still censored ...
But yes, such databases usually are made by the community so it is not that untypical that at least some information is wrong. That is why I think that forums are such a good thing. Here you can ask actual owners of these games if they are censored or not.
