Hum, without any judgment on the interest of the scripts available on your blog, I don't know if posting a direct link to those scripts is compliant with the forum rules ??

The scripts aren't on the blog.

Quite true

OK:

So I want 'The Dark River' by john twelve hawks. on fictionwise it is $17.89 and on Amazon for Kindle it is $9.99! Big difference!!

I don't have a Kindle, but theoretically I could get the kindle version, and dismantle it with this tool, then format it for my Sony, with various tools.

How can I but the kindle version without a kindle though?

You can't. I look on the $400 purchase price as including a subsidy for bestselling e-books (i.e. you are overpaying for the Kindle if you never buy discounted e-books from Amazon).

The Dark River is $14.36 at BooksOnBoard.

You probably can't use this tool to dismantle that ebook. If they offer a sample chapter then this ebook was likely licensed to amazon through the publisher channel, not the DIY channel. The ebook probably has DRM that would make it incompatible.

There are actually 3 file types sold by Amazon: AZW, AZW1, and Topaz (TPZ or TAN). AZW is Mobipocket format and usually has no DRM. AZW1 is the DRMed Mobipocket format with one extra identifier added to the file header. Topaz is slightly different from the others and it has more features.

From my experiance, I think some AZW are DRMed, some are not (mostly the thirdparty production). And AZW1 and TPZ are the same thing. The topaz format is mostly used for tech manuscripts and the books with special formatting because it can use an embedded font and scanned text/equations.

Sorry, but my e-mail and blog posting to darkreverser aren't getting any responses. Has anyone successfully run mobidedrm using the Python that comes with Mac OS 10.4? It's Python 2.35, and I get syntax errors. I could upgrade to 2.4 or 2.5, but it's not like I run Python for anything else, so I wouldn't go to the effort if it just plain won't work even with an upgrade.

(If it's any help, the book I'm trying to "liberate" is the free "Around the world in 80 Days" from fictionwise.)

The version of Python used probably would matters more rather than which platform (Windows, Mac, ...) that you use. I can confirm that the script works on Python 2.5 / XP, so try to upgrade your version. It's not too much of an effort anyway :P

I *have* done it on a mac, 10.4.11 -- but I didn't realize python was already here. I downloaded and installed the new one pointed to. It works great with that! Quite easy.

I never got the mobiperl set of scripts to work, though ..... I eventually download the executable for a PC, and used it easily that way.

When you said "new one pointed to," did you mean ActivePython at activestate.com? I was considering the "official" distro at python.org...

I have Python 2.5 for XP and I've not had any issues with Darkreverser's scripts due to the version of Python.

I'm having errors running the script. I have activestate python on XP and I'm trying to liberate the free Around the world in 80 days from fictionwise. The PID I have is from my laptop installation of mobipocket reader. Could it be problematic that it contains a $, which could be badly expanded as a variable at some point?

I feel like I'm missing something very obvious. Granted, it is monday morning, but still...

I've gotten the python script to work (for some reason, it does not like my XP box but seems quite happy to work under linux) and converted Aroundtheworldin80days.prc from fictionwise. Having said that, I tried to use the python script to decompress to HTML that has been mentioned earlier in this thread and get the following error:

MobiHuff v0.02
  Copyright (c) 2008 The Dark Reverser <dark.reverser@googlemail.com>
Decompressing...
Error: invalid compression type

Furthermore, if I try ABC Palm Converter (heck, the file has a PRC extension, might as well try), I get gibberish as HTML output.

The end goal I'm trying to achieve here is to convert a DRM mobi file into plain HTML so that I can put it on my sony reader.

What's the missing step here folks?
