viewer from ebookjapan down?
« Reply #214 on: October 15, 2015, 05:56:39 AM »
hey folks,

ebookjapan is my favourite site for buying manga. viewing and ripping went without a hitch in the past. unfortunately the viewer has been updated and now i can't flip pages anymore. this concerns previews from ebooks i do not own yet and books from my bookshelf. you can see the arrows for flipping, but they're just images. this has been going on for a few days now and i checked java and whatnot and it all works fine. the viewers from booklive, shonen jump + and comic walker work too.

i'd appreciate any help.

btw i'm new to this board as i was active only in winny club until now. i searched for a similar topic but found nothing. so if there is one already feel free to delete or relocate this post.

Ok, this has been fixed for EBJ downloads:

Hmm... I guess I should have hit refresh before I posted.  Sorry

A fan of Comic just simply change the image addresses from Comic-Walker to Gangan Online and it works perfectly for the newest update of Gangan Online.Here is the nw file,Download link:  the method to use is the same as what the quote said.
But I just found that it is not worked for Jump+,because it is based on 64 bit text but not the original pic,but it is simliar to comic-walker and gangan online,hope @Poligrafowicz can solve the problem ,thanks!


Eh, Jump+ and Comic Walker are easy, I just use the command-line tool cause then I can grab all the old chapters too. Guess I'll get working on the EBJ thing, there's a couple volumes I wanted to buy. Thanks.
(By the way might want to spoiler the link.)

I did that and get "invalid or corrupt jar file" when I try to execute it.


Use the function of Eclipse's "export".
Sorry, please read the forum rules to see why you can't view spoilers and why you can't post in this forum section. Thank you!
First choose the folders to  "export"
Then choose Java -> Runnable JAR File ,click "NEXT"
In the JAR File Specification Runnable window,choose "Launch configuration"and"Export destination".
Finished. :)

It's still perfectly rippable, but the program is expecting the old URL so it won't work. You can directly change the ripper's code to make it work with the new URL in about five seconds if you know how to do that, otherwise you can probably just wait for an updated version to be posted.

I can't guarantee it'll always work for all pages in all chapters of all series, but it might actually work better than the ripper did (from what I've seen in the code, the ripper only successfully decoded some pages of some series). I'm really grateful to whoever wrote the ripper, it spared me days of reverse engineering obfuscated javascript and\or brute forcing the segmentation sequence (I actually kind of started that...).
Long story short, they slightly changed the URL of the viewer. It's still perfectly rippable, but the program is expecting the old URL so it won't work.

I really should be able to do this myself but Ant is screwing up on me so I'll just wait for the update.
By the way, any word on an update for Gangan Online?

I tried to understand the conversations here, but the fact is that I cannot understand what I have to do. It is impossible (at least to me) to download from EBJ. OMD simply says that it is unable to autodetect (or something like that). Can anyone inform, please?  :huh:

I have written the booklive module for OMD. You can reimplement it in python (like the tool for sokuyomi).
Sorry, please read the forum rules to see why you can't view spoilers and why you can't post in this forum section. Thank you!
It also need the cookie to get the content.

I have tried this, only the first 10 pages can be ripped from booklive.
Would you fix this , please !

Thanks for the feedback, guys. Great to hear that it seems to work.

Any chance for external version (without "hacking" original viewer)?
Nah, not with this approach. I might be able to do something if it was possible to decompile the .NET code (in fact, an older version didn't require starting the viewer) but since I have no clue what kind of obfuscation they used... (code encryption?)

I prefer external program in case (if) BW will check program integrity and ban "cheaters" :/

I don't want to lose access to 400+ books (even if most of them were ripped in prevous version).

Regarding ripping from Bookwalker, I'd appeciate it if someone could test out this (experimental) tool I made:

Sorry, please read the forum rules to see why you can't view spoilers and why you can't post in this forum section. Thank you!

To install, just extract the files into the Book Walker directory, overwriting all files. This will add a new button "Extract" to the Book Walker viewer.
Sorry, please read the forum rules to see why you can't view spoilers and why you can't post in this forum section. Thank you!
If the button doesn't appear, try restarting the application. (Apparently, it didn't work on the machine of a Japanese friend, so I'd like to collect some data.)

Looks like Gangan Online has a new reader that is the same as comic walker now. 

Anything for Young Animal Densi yet?  Might be hard to do because it has a really long link text and it just might be shorter to just screencap the pages.

I just found a bug in the latest version of V2.0beta 2.
The color of images downloaded by your program is not accurate. The backcolor of the images on the Comic-Walker Website is pure white with RGB(255,255,255), while the backcolor of the images downloaded by your program is a little gray with RGB(255,254,255).
I haven't checked your source code, so I don't know why this happens. For reference, I had met silimar problem before, for that pure white turn gray when using the official webp image library of Go language(code.google.com/p/go.image/webp/). Maybe your image libary has some problem, and you need to change a better image libary.
New edit: I just found that it is the fault of the latest nwjs-v0.12.3. I use node-webkit-v0.11.6 instead of nwjs-v0.12.3 (http://dl.nwjs.io/), then the pure white looks well with RGB(255,255,255)!

By the way, could you write a new version that supports for Jump+ (http://plus.shonenjump.com/) ?
Jump+ has a similar way of image encryption as Comic-Walker. I think the comic websites of Jump+ and Comic-Walker are both developed by the same company.

If that helps anyone, the application spawns a process that attaches itself to it as a debugger (so you can't use your own). I use ProcessHacker to force detach.

As a noob in programming, I have been itching to find a way to extract from the new version of Bookwalker. Nothing good so far, here is what I have been through, so I thought I would note it if it helps:
1> Database password/structure change. New tables, keys/XOR phrases are encrypted (by CryptoJS). So even if you use the new version to download the ebook and try to extract using the old one, it would not work because the keys are different (encrypted). So is the liscenseUnit file.
2> Bookwalker.exe is strongly obfuscated. Unlike the old version in which we can decompile and read the source code (which makes up most of the code in the old extractor), this time it is protected so I have no idea how they encrypt the keys. Using de4dot only reveals partial code, which does not help much.
3> Trying to decompile DecLib.dll allows me to understand that some new functions have been added to the dll file, which can help decrypting the data. I got all the EntryPoint and function param using IDA, but still cannot link the dll in VS. Guess what, I think the dll is protected against unauthorized use as well, and I am too noob to figure out the way to bypass the check. At this point I decided to give up and hope for someone better to save the day. Well, cannot expect much from a total amateur anw :(

Anyone who still keep bookwalker ver 1.2.1, could you share it with me? Or could you teach me how to rip from 1.2.2?  Sorry for my terrible english

Is there a program that allows downloading manga from mangapark?
