you're right. I'll post a bit later extension for launching standalone CoolReader3 application.
If you'll follow my way you'll need to:
1) copy the archive's content (its 'bin' and 'share' folders) directly to your "/mnt/us/cr3xcb" folder on Kindle Touch (in case you're connected by SSH).
Or just connect Kindle Touch by USB, create that "cr3xcb" folder and copy there these folders.

So the final structure would look like:

cr3xcb
-> bin
-> share

2) After that the appropriate GUI launcher extension for CoolReader3 will be ready, It will take us just to register our CoolReader3 for GUI Launcher as an ordinary GUI extension.

There should appear a new command in the Launcher menu on Kindle Touch. Yup, it will invoke CoolReader3

But, as I said, I didn't have enough time to create that extension. So, please stay in touch.

When confirmed and complete it could be a useful "Unofficial instructions for installing Kindle Touch Hacked Up Reader for epub" for those willing to try it.

Please note: these instructions are for Kindle Touch only.

1. WARNING!!!
   By trying to apply the following hacks you can potentially destroy your Kindle Touch. You are advised, so do not complain if it happens. Anything you do is at your risk.
   • Do a COMPLETE BACKUP before trying to do anything. Better to do a backup than whining you've lost your files.
   • Don't try to do anything if you don't understand (and don't even think about it without a complete backup). Ask instead. Your kindle integrity is worth a little waiting.
   • And remember to do a COMPLETE BACKUP before trying to do anything.
   • At the moment the following instructions are not confirmed by packagers and may change at any time: DO NOT FOLLOW THESE INSTRUCTIONS unless you really want to risk. However reading them should be mostly harmless (but I would suggest a complete backup, just in case )
2. jailbreak
   The following will work only on a jailbroken kindle device. This is mandatory.
   Follow these instructions to jailbreak youd device.
3. libfreetype library (by varnie, packaged by ixtab)
   This is not mandatory but coolreader3 font rendering works much better with this library.
   There's a libfreetype bin package that can be installed/uninstalled by putting it on the top of the USB accessible directory.
   If something is messed after first reboot, reboot once more.
4. hackedpubreader extension for GUI launcher (by bhaak)
   This is for loading the coolreader3 package via the yifanlu GUI launcher (which integrates it into the main kindle menu interface: get it here)
   There's a hackedpubreader extension for GUI launcher that can be copied in the "extensions" directory of the USB accessible directory.
   
   To activate it you can follow two approaches. Both require that you access your kindle via ssh as root.
   • This solution modifies an Amazon installed file, at the risk of losing changes with a firmware upgrade. Login as root via SSH and execute these commands:
     

     mntroot rw
     cat /mnt/us/extensions/hackedupreader/hackedupreader.policy >>/usr/java/lib/security/java.policy
     mntroot ro
     killall cvm

   • Login as root via SSH and execute these commands:
     

     mntroot rw
     cp /mnt/us/extensions/hackedupreader/HackedUpReaderExtension.jar /opt/amazon/ebook/lib
     sed -i -e 's|jar="\([^"]\+\)"|jar="/opt/amazon/ebook/lib/\1"|g' /mnt/us/extensions/hackedupreader/config.xml
     mntroot ro
     killall cvm

5. hackedpubreader binaries (by bhaak)
   This is the epub reader core package
   The reader binaries are in the zip in https://github.com/bhaak/HackedUpReader/downloads. This zip contains a cr3xcb directory which has to be copied on the top of the USB accessible directory (/mnt/us)
6. hackedpubreader binaries alternative (by varnie)
   As an alternative, varnie has compiled a modified version of the binaries with a working "open ebooks" feature. The zip file consists in two directories (/bin and /share). They replace those in /mnt/us/cr3xcb. A specific GUI launcher will be released soon.

Howdy.

As I promised, I implemented the simple GUI launcher. it can be obtained there: https://github.com/varnie/HackedUpReaderLauncher
Simple instructions are also provided.

As for libfreetype library issue I am kinda confused. I hope I didn't mess anything up. If I remember correctly, I didn't put my own built one to the Kindle file system.
In any case, here's which one I have there on this moment:

-rwxr-xr-x 1 root root 700.1K Nov 3 20:05 libfreetype.so.6.3.20

I can confirm HackedUpReader works well with this one.
And I am running 5.0.4 official firmware if it matters.

So, for those who would like to attempt my approach, here are some brief instructions:

1. download the archive from https://github.com/varnie/HackedUpReader/downloads and extract it directly into /mnt/us/cr3xcb
2. follow the instructions for my simple GUI Launcher extension: https://github.com/varnie/HackedUpReaderLauncher
3. now you should be able to invoke HackedUpReader from the Launcher menu

ps: I've uploaded several screenshots.

Thanks

error: wrong document size
cannot open document

it happens when i try open books over 1mb size

[varnie]

Tsukasa,
what is that file's size exactly?
There's a check whether the file size is less than 5 bytes, I suppose. and in that case it prints that message on the screen.

[Tsukasa]

sory for desinformation

this happens when book placed in subfolder in documents folder
CR3 can see the books in subfolder but after trying open it create 0 byte file in documents folder with same name and write that error

or maybe its because russian folder names, but mobi whith russian name opened normally from documents folder

with CR3 we need the mess of all books in one folder(


in any case, a big thanks for work, its already usable version

[varnie]

Tsukasa
thanks for the info. I'll try to fix it. as for now, generally speaking, putting ebooks into subfolders doesn't work.

[acajac]

Varnie, Tsukasa, thanks a lot.
I have a question. The minimum font size is 32. Right?
So, It's not available to decrease it less than 32.
To me, the size is little bit big to read books.

[Tsukasa]

font sizes 16-62

to choose smaller than 32 tap on left half of black down bar

PS and read the instructions down bar is a left and right buttons

Tsukasa,

A thousand thanks~!

Could you let me know where I can find the instruction?

[bhaak]

Wow, lots of activity

@bhaak: how?

Change this line in config.xml

<menu type="java" jar="HackedUpReaderExtension.jar">com.github.bhaak.HackedUpReaderExtension</menu>

to

<menu type="java" jar="/opt/amazon/ebook/lib/HackedUpReaderExtension.jar">com.github.bhaak.HackedUpReaderExtension</menu>

The GUI launcher must be able to locate the HackedUpReaderExtension.jar, either by relative or absolute path.

The original libfreetype library has issues with custom fonts (didn't you say that it crashed for you, too?) and I think it doesn't provide any kerning.

But if you only use the stock fonts, AFAIK you shouldn't have issues.

Good day, bhaak
hmm, maybe you're right. It seems I forgot what I did :-/

I done several valuable features and bug fixes in CR3, so, if you'd like I could send you a pull request.

I updated the files handling in the newer version. Now it should handle subfolders without issues. Please give it a try and write back.

Thanks for fixing that, I'll have to try it later.
It seems to be randomly making files named after books I read which appear in the main kindle book list, any ideas why its doing this? (on the version before the subfolder update)
