I posted those archived grajapa instructions in the announcer general. Back then, modelpressdownloader(MPD) didn't support grajapa, but
they've added support since then, so I don't have to decode the base64 anymore. I still manually rip videos out of grajapa PBs by finding the video source m3u8 links in Firefox's web inspector and downloading them with yt-dlp. (I use firefox since grajapa's anti-devtools
script doesn't support it, but I guess a user-agent switcher should work too). I download youngjump's 4K videos the same way, though
I buy YJ PBs on grajapa since MPD doesn't support YJ's site (the images are 1500x2117 on both sites). I use MPD on yanmaga and https://kokode-digital.jp/products/list?category_id=11 too. I buy PBs from Friday and other random publishers on https://books.rakuten.co.jp/ rather than amazon since amazon shrinks pages down to 1079x1920. On rakuten and other sites that display decrypted images within html canvas elements and aren't supported by MPD, you can use the "canvas downloader" extension in chromium. (I'm still trying to find a way to rip the original image files from rakuten by running custom javascript somehow, but for now I use their web viewer since it's at least zoomable)
