How to change Wallpaper 
=======================

1. Load the firmware .sre file
2. Find start address (for example write 2ABE99 into start address field and then click "Draw" button) 
3. Select 4P/B Compress format. Now you can see "Sony bird"
4. Cut the current window with arrow buttons until it has exactly the same size as the picture. 
In this wallpaper example you need 96x77 pixels window. So press arrow up button until the 
height of the window will be 77 (current width ans height is displayed near the buttons).
5. Press "load BMP" button and select your favourite picture
6. Now you can see the result of resampling. If you don't like it, simply press 
Ctrl + R and you can see the previous content.
7. If you want to write the new picture into FW file, click on the "Turn on the edit mode" checkbox
and press Ctrl + S or "Save changes" button.

8. If you press Ctrl + R now, your new picture remains on the screen. It means it has been 
correctly written into FW file.

How to change icons
===================

Be carefull, it is less tested than every other modes!
1. Switch into 8B/P mode
2. Reduce window width to 16, (if you want to use LoadBMP image, reduce also 
height to 12 pixels, but I don't advise you to use this functionality)
3. Find icon, you want to change (in 5.1.4 FW icon are around the address 29D54D (that's me :)))
4. Turn on the edit mode
5. Use black (pixel present) and dark grey color (mask) to change picture
Be careful to change only the parts you surely know that icon is!! Don't change anything around!
6. press Ctrl + S to save your work.
