Hello Everyone

I purchaced 2 H-Doujins from DMMBOOKS R18 but the files (.dmmb) WTF is that?!. Does someone know some program to turn them in .jpeg or extract the Images? The doujins are the following ones:

Thanks for the Help!! (IMG:[invalid] style_emoticons/default/sad.gif)

It's a DRM that needs you to use a program to view them. This program prevents basic features like print screening, and it encodes the files so that they can't be ripped easily. I don't know if any decrypting program exists, but I doubt it. I haven't seen one, at least. I think the encryption is account specific, so you'll need to log in to view the files. That's how it works for DLsite DRM stuff as well, I believe.

Just stay away from dmmb stuff. These are cheaper releases for a reason (usually cost a fraction of the non-DRM stuff). Many releases are only available as DRM copies or as physical copies, which may be sold out, and are thus hard to get a hold of.

Remember the A-hole and similar tricks in the digital domain like copying video card memory and the fact that some are just wrappers with the original PDF/DJVU/JPEG/etc. hidden in RAM(!) that can be dumped. But yes, it's easier to just not buy DRM'd junk in the first place. If you're serious about viewing them, I'd recommend setting aside a hard drive just to boot to view DRM'd junk. Some of the DRM tools can royally break Windows. The usually block VMWare and such.

Oh, and good luck getting most of these eBook DRM's to run on 64-bit Windows or Linux. Considering that most computers now come with 64-bit Windows... D'oh!

DMMB is a drm format for CG sets specific for DMM portal. It requires you to install their application which is the only legal way to view such sets. First time you open a particular set, you must enter your DMM account details into the login form, then a license is installed into your system and you can access the set any time with this application. You may need to authorize your protected works again if you decide to format your hdd or reinstall the OS.

Problems are, this application only exist for Windows and Mac systems, also some aggressive drivers are being installed along with it which are active at all times and may cause a system to freeze (not often, but it happens if you use some specific debug software or virtual drivers). They make it imposible for a normal user to screen-cap any part of viewing application while it's running. Some users have problems installing this software or running it, so the portal allows you to install some kind of a demonstration for you to see if it's compatible.

Using some of tips you can find on some public discussions, you may be able to fool the software so it allows a screen capture. However you may need to resize and convert the results, that would be PNG if you want to keep the quality.

As said in other threads, I can help with decrypting such protections via PM, if a member shares the file and login information with me. The result is 100% virgin files (original JPEG's in DMMB case) with original filenames. This also means you don't need to install or run that drm software yourself.
Downsides are, you may not like sharing your login info with anyone, and it will take more time if you want to decrypt several works.

I've been helping several users already and some of them mentioned me in their uploads.
I may refuse to help with decrypting a work if I already have it decrypted and want to publish the gallery myself. Rarely happens.
