This just gets better!
Works fine now on my unbranded 220x176 Rockchip.

Writes the offset to the .lst file now so I can now theme ok.
Noticed one slight problem though I can't get the crtl-a , ctrl-z line shift to work for me.

thanks dancemammal I've no need for RKLogo anymore, yea!

Hi All,

If you wish to use the Ctrl A - Z, make sure the cursor is inside the offset edit box,

I have not forgotton the Actions chip users, the firmware seems to be encrypted with a MD5 hash, the problem is not decrypting the stream, it's finding the embedded encrypted password.

I am currently converting some old code to try to do this, it could take a little time,

Ill keep you all updated,

Cheers

Hi Dance,
Could you allow long press of ctrl a -z?
I still can't understand how the item adding works.
I find an image with offset width and height,i click add item with set rect,but when i go see it,it's not the same,it save the image on start offset.
I tried adding the offset on the item dialog,but it's same.Could you explain me how it works?

Hi All,

The main problem with editing the firmware, is finding the start position of the images, using the width and height and the offset edit boxes, you can find the first image, then, you need to set that position as your start position, use the "Set as Start" button to log the offset to your new Lst file.

All the images after that, will be taken from that start point,
You can then create your new item, and then you are ready to move onto your next item / Image.


Explanation,
Rather than use the offset in the item, I scan the lst file and find the offset by multiplying the image sizes to create the offsets on the fly, this then lets you edit and insert items into the lst file, and every other offset compensates for the insert / edit.


I will try to pad out the User Guide when I get time,
Hope that helps

Cheers

You need to set the start offset using the button on the first image correctly lined up in the .lst first.

Then save the .lst, then exit the editor and reload, you should find the first image is in the correct postion which means the start offset is now set.
Don't set the start offset again you only need to do it once.
Then all you need to do is line up the all following pictures create a new .lst entry, set the rectangle and then resave the .lst after each change.

This is the only method which worked for me.

Using the new software is much better method of creating a .lst by far and has really speeded up the process.

I did find if you tried to reload a .lst a again the application gets stuck and I had to kill the process, so just a small bug there.

Thanks for your tool Dancemammal.

I have some problems with images, because they look kinda compressed in your editor. I'll greatly appreciate info on the format in which images are stored in the firmware so that I can find them in WinHex or some other editor.

[Dancemammal]

Hi,

I think you may have to give me more info than that,
can you see the image?
is it squashed because of the width / height ?
is it an Actions chip (encrypted) ?
what model is your MP3 player,

Images are stored in 16bit bitmap format in little endian byte format, with no pallette info, You may have some difficulty opening the images in a hex editor due to this, and is why we have to write these applications.

Thanks for your reply.

It is Rockchip RK2608A with touchscreen 320*240. After the first touch it does not start the app, it just changes it's icon.

Oh, little endian means that I should search for MB and not BM? Thanks again.
