DMM Version seems to be x1200, not sure why screenshot. Would take a look over at the forums to get a better/proper rip.
Seems DLsite is the way for the Wani for x1500.
@Acetominaphene hmmm how Recent? I bought a few Wani books in the past 2 months that were released at the earliest in May 2023. EPUB and all were x1200.
so likely it will be 1500px or maybe 1600px (dmm updated their epub resolution in recent year, 1200px would be their legacy release). uh yeah, wani at dmm always 1200px. they never changed that.
so OP I'd give you a chance to update your gallery. Just archive download my private gallery and replace all your screenshot with properly ripped 1200px images. Here you go: https://e-hentai.org/g/2606521/a3a32709fe/
never mind, this gallery will be replaced since dlsite's content is absolutely the same except they are higher res.
