Made this to replace https://e-hentai.org/g/2989336/d140cebadb/

Replaced all the pages that didn't have any censorship with the original PNG files from the non-decensored version (Note: The 4th page wasn't decensored so I replaced that too)
Added missing credits page

Perfect! Thanks for the effort. Could you do the same with this one? https://e-hentai.org/g/3150191/a1bc29a13f/ Even with proper translations, the first four chapters used COMIC Shigekiteki as RAW, so they have different sizes and mosaic censorship. So, it would be necessary to replace them with the manga version that has less censorship.

@Coledas What's stopping you from doing it? You dont need paid software to do that, and its not difficult unless you want to do SFX/Typesetting. If your just merging a translation then all it takes is a bit of time, and to find the right fonts. There's plenty of places where you can find commonly used fonts e.g Wild Words. I've done this once a few years ago now for a chapter I was annoyed was only available on a low quality raw. Took me a few hours for a first attempt

@ Black-lights

Didn't understand my question? I asked if you could do this, if you can't or don't want to, then OK, subject closed.
