Typing:

Code:
mobi2mobi --databasename "Some_Name 32_characters or less" --outfile "New ebook file name so I don't screw up the original one.azw" "bookname.azw"
...and hitting Enter will create a new azw file (with the name you gave for the --outfile parameter) that should work with Mobi2Mobi-Gui.
Wow. That works! Thank you so much!

Thanks for the troubleshooting DiapDealer. Do you know if there are any public domain AZW files that have this issue that I can get for testing. I'll see if I can put some error checking in place to get around this problem in the GUI. Cheers.

I'll see if I can track down some freebies that have the problem.

Mobi2MobiGUIv10beta - Null DATABASENAME fix for AZWs

Okie doke.. Thanks to my handy HexEditor I was able to replicate the missing DATABASENAME error in the AZW files. The way the GUI works is that it creates a temporary working copy of the PRC/AZW/MOBI file when you initially open the original. It creates a text dump of the Mobi2Mobi output and parses that information. Because the dodgy AZWs can't be output to a new file without a valid DATABASENAME entry the various files don't get created and the parsing routines all die and create and exception error. I've created a workaround that checks to see if the Mobi2Mobi output file has any data, if its empty and the file type is AZW then it assumes the DATABASENAME is dodgy and fixes it by using the AZW filename as the default. It then re-runs all the parsing on the updated file and it all works. Can those with issues please give this ago and let me know if it sorts out your problems. I'll probably need to add an option in somewhere to allow modifying the DATABASENAME entry so you can change it to something else if you don't like the default.

Edit: Oops.. Just unzip the new EXE into the same location as your original Mobi2MobiGUI_VB.EXE and run it.

Sorry I didn't get back to you sooner, but your latest changes do indeed fix the problem I was having with Amazon books that were missing Palm Database names. Thanks for the update. Will you be making a LoRes version with the fix, as well? No big deal if not—as I can make my own if need be—but was just curious.

Thanks again.

A LoRes version will be forthcoming. I'll probably put up an official v10 tomorrow. Thanks for testing.

Hi, first time using the forum so apologies if this post appears in the wrong place. I read a posting where someone was saying that if you use the mobi2mobi program to edit the clipping limit your book will no longer be readable. Nobody seemed to follow up on this, does anyone know if this is the case? I haven't used the program yet.

If you bought the book from Amazon and you're trying to remove the clipping limit WHILE the ebook is still DRM'ed, then yes, the ebook may be rendered unreadable. The clipping limit (and TTF flag) are now tied into Amazon's DRM scheme, so if you want to modify those two attributes (clipping limit and TTF flag), you are essentially forced to remove the DRM from the ebook first.

Basically, we no longer have the ability to tweak those two attributes on DRM'ed Amazon books like we used to be able to do. This is not a problem with mobi2mobi, but rather an insurmountable change to Amazon's DRM scheme.

Remove the DRM or deal with the existing clipping limit (and TTF setting). Those are our options now.

Title on GUI is Correct but Not On Kindle

I apologize if this is a repeat but I did not see this in the thread.

I have been trying to change the title of a .mobi ebook. When I open it with the GUI initially it has the bad Book Title of "0379854001312042501_valkyrie_02'. I changed the Output File, Book Title, and Author. This created a new output file with the correct name and accurately changed the author when I copied to my Kindle. However, the title on the Kindle is still "0379854001312042501_valkyrie_02" even though when I open the new output file with the GUI the Book Title listed is "IAD 02 - A Hunger Like No Other". I think it has something to do with the Updated Title still being "0379854001312042501_valkyrie_02". Could someone help with this? I am using:
mobiperl-win-0.0.43
Mobi2Mobi_GUI_VB_v10
.Net Framework 4.0


PARTIAL GUI INFO:
Database Name: 0379854001312042501_valkyrie_02
Version: 0
Type: BOOK
Creator: MOBI
Seed: 175
Resdb:

Yes, you've essentially changed the LongTitle of the ebook, but the Kindle uses the 503 EXTH record for displaying the titles.

After you have the ebook open in Mobi2Mobi-Gui, look for the combo box (dropdown) labeled "exth type" and choose "503 - Updated Title" from the list. Enter the name you want into the field beside it labeled "exth data", tick the checkbox beside that and hit the "convert" button.

Ok... I THINK I downloaded all the newest versions, and pulled the newest .NET from Microsoft (I hope that works), and I tried DiapDealer's suggestion above to change the title that would read in kindle, but when I convert the file, the 503 exth data in the modified form of the book (within the GUI) showed: EXTH item: 503 - UpdatedTitle - 0 - , and when opened in kindle, showed it as being untitled...
What did I do wrong, and how can I fix it?
