Kobo Patcher

[PeterT]

The size of this and some other threads is why I had suggested some time back creating wiki pages to hold the pertinent data. Imagine for instance the ease of a single, easily maintained wiki page for each f/w version detailing the patches for that version.

Thanks a lot, GeoffR.

Hi GeoffR,
i'd want to use the patch "My 14 line spacing values", but i do not understand how to edit it.
i'd want to use these values for line spacing: 0,7; 0,8; 0,9; 1,05; 1,07; 1,1; 1,15; 1,2; 1,25; 1,3; 1,35; 1,4; 1,45; 1,5
Can you help me?
And an other question: if i enable this patch, do i have to disable the other patch "My line spacing values"?

The extra four values can only be chosen from the tables A or B listed in the patch. (I could make a custom patch that would use other values, but then it becomes even more complicated to explain.)

For example you could have: A; 0.8; 0.9; 1.05; B; 1.1; A; 1.2; 1.25; 1.3; 1.35; 1.4; 1.45; A; where the As and Bs are chosen from the appropriate tables.

The closest to your example would be: 0.6875; 0.8; 0.9; 1.05; 1.075; 1.1; 1.1875; 1.2; 1.25; 1.3; 1.35; 1.4; 1.45; 1.5;

The only difficulty is that 1.1875 is very close to 1.2; You could leave out the 1.1875 and 1.45 values and use just 13 values instead: 0.6875; 0.8; 0.9; 1.05; 1.075; 1.1; 1.15; 1.2; 1.25; 1.3; 1.35; 1.4; 1.5;

And an other question: if i enable this patch, do i have to disable the other patch "My line spacing values"?

Yes.

thank you very much GeoffR. I had success
I hope you will do this job also for next firmware releases, it's wonderful!

Hello, I have the Aura running 3.1.1 and I tried the kpg.conf from Post #605 with the patcher for firmware 2.86 (replacing the included kpg.conf). But when I try to run kpg.exe I get the message

File "<string>", line 170, in <module>
TypeError "NoneType" objekt is not iterable

Can somebody tell me where I make a mistake??

You have to use the patch for 3.0.1 (patcher 11) and extract the right (3.1.1) libnickel file.
See here for how to get the right libnickel:
https://www.mobileread.com/forums/sho...&postcount=549
Patcher version 11 is needed to : http://rghost.net/50558386
For a good kpg.conf see here:
https://www.mobileread.com/forums/sho...&postcount=605
Your mistake is that the libnickel version you used is wrong, you have to take the libnickel voor version 3.1.1 and the patcher version is wrong, you need version 11.

Thanks for all who helped me pointing out how to do it, so I can point you out now how to do it.
I hope post 1 can be updated for patcher 11 because it is all a bit fragmented now

[SONOiO]

Great, it is working again, thank you very much, Nick_1964. And you are right, the information is wide spread, all these posts are 50 pages or so. Maybe there should be a sticky post with no questions asked?

Thanks again, have to go reading! :-)

No thanks at all, I was wondering before you how on earth must it be done.
I got a lot of help from a lot of friendly people on this forum, and I found all the posts needed,so it was easy for me now to point you in the right direction, but none of the articles is from my hand so again,no thanks.
I think the person of post one "must" update the post, for now I think my post contain enough information bundled it all
By the way, more "patches" can be found here :

Whats your version of the firmware ? The file in post 605 works just fine on 3.1.1.

Perhaps we should start a new thread for each new firmware version, with the opening post containing the set of patches and instructions on how to apply them for that specific firmware version.
