Be patient.

Or try updating the patches from the previous version yourself. All you need is a text editor, grep, a hex editor, strings, and objdump, and a bit of patience. If you want to do this, a hint is to replace all:
- strings -el with strings -es
- \0 with nothing
Then, the rest is pretty straightforward if you have done this kind of thing before.

But I wouldn't recommend trying to update the libadobe patches, those are harder to do correctly.

Oh sorry, i think it´s better, for my kobo and me, if i´m waiting !

Where do you use it? The rest, I've already done it, and updated translations.

It's in the comments for the full screen reading fix. It is used to find the string offset for the CSS. The string is not padded with \0 anymore too.

Ok, I haven't seen it because I don't use it. Thank you very much.

Nothing to see here. Move along. This thread is in the wrong forum and there is already a thread there.

If you only use Windows and you haven't done it before, is it still do-able, do you think?

Well, you would need the GNU binutils built for windows, which you can get through MinGW. You would also need tar and unzip, but you can use 7-zip for that. And for the hex editor, xxd is pretty comparable to wxHexEditor.

As for the do-able part, it depends on how much experience you have with software development, and how fast you can learn things. Just play around a bit, but be warned that an incorrect patch can brick your Kobo and need a SD card reimage. The strings are pretty safe to change, it is mainly function arguments which are easy to corrupt. You may want to use a Linux VM so you do not need to use Windows tools, and also practice modding other executables first to get an idea.

For learning, there was a thread about 2 months ago about how to make mods. That thread is pretty useful starting point. This is the kind of thing which you learn by doing.

Yes, I remember looking at that thread and trying to make sense of objdump, but had to accept defeat and my own limitations.

I've been able to create and share a few css-type Kobo patches in nickel and libnickel.so.1.0.0 but I think that's going to have to remain my limit. Thanks for the reply, anyway.

Don't give up yet! Even I don't completely understand objdump. No sane person would be able to read it like a book. It's just about finding useful strings and functions and searching for the position in the output of objdump.

But that's the point - I couldn't get it to output anything. I'm sure this must have been a very basic misunderstanding on my part, but that old post didn't claim to be 'objdump for Dummies' - which is probably what I needed to get started

Did you extract libnickel?

Because I didn't have any success I didn't make notes of what I tried but I'm fairly sure the file I was trying to look at was libnickel.so.1.0.0.

I wanted to see whether I could understand how GeoffR had created patches such as `Freedom to advanced fonts control`, i.e. the patches which aren't some variation on a CSS tweak.

For the first time those patches are made, a proper disassembler like RetDec or HopperApp are a lot more useful, as they show the program's flow.
