Hey, regarding the translation of the Sana Game, there is one linked earlier here:
I’ve just played it through and found it to be a pretty good translation. There are some small errors like a boy is referred to as “give ITEM to her” instead of him. But that Pretty much it
The gallery is pre unlocked for the most part (which it is by default from the original Japanese version when reached the final ending). There are still a few gallery scenes to unlock which you can get some clues to on how to unlock by visiting the “empty slots” in the gallery. Unfortunately I was very confused by two of the clues due to most likely translation.
I rewrote them here:
You just get the base v1.5b and copy paste the files in the root directory and you are set to go.

I’m currently working on a GoogleSheet which could act as a kind of walkthrough. It’s not finished yet, but I can share it if it is of interest. Just hit me up!
