I didn't used any programme to extract the content, so I have no idea how to get character sets That's also the reason why I didn't get 026 and 065 in the set.
and all files in this gallery is in the same order of the game gallery, if you want something like sorting by route, you can do it yourself
I had consider sorting by route, character or just by EventCG, HCG and SDs, but it seems that using the gallery order is how other people do, so.
