One of the 'features' lost along the way in Primo is the ability to have both a separate loading AND exiting screen (Primo 2 and others ignore 'exiting.bmp').
Now you can have both and customize them as you please without having to edit either branding.zip or data.zip...just follow the steps below.
1) Create your custom loading.bmp and exiting.bmp. Both must be exactly (in pixels) the size of your screen resolution (800x480, 480x272, 320x240, etc). You can use any graphics editor you like, but the resulting images must be sized precisely to your resolution size, be in 24 bit color depth, and saved as standard "Windows" bmp format. In KB size, the images must be exactly this: 320x240 = 225 KB, 480x272 = 382 KB, 800x480 = 1.09 MB. If, after creating/editing/saving, your files are not these KB sizes, you have done something wrong and must start again.
2) Rename your saved loading.bmp to loading.jpg...note: do NOT convert the image to JPG, just rename the file!
2a) Rename your saved exiting.bmp to loading.bmp.
3) Go to your main {Primo2} folder on your device or SD card.
3a) If there is not already a folder in the root named UI_IGO9, create it...upper or lower case is irrelevant.
3b) Inside the ui_igo9 folder should be a folder with your resolution size (480_272, 800_480, or 320_240). If this subfolder is not already present, create it...the underscore "_" between the numbers is significant, and no spaces. Inside the resolution size folder should be a subfolder named skin_night...if this subfolder does not exist, create it.
3c) The resulting folder structure should look like this:
Primo2 (or whatever your main Primo folder is named)
>ui_igo9
>>480_272 (or whatever your resolution is)
>>>skin_night
4) Copy your saved loading.jpg and loading.bmp files to both the 480_272 (or whatever your resolution is) and the skin_night subfolders
5) Open your existing sys.txt file in a plain text editor and add these lines:
[loading]
loading_bmp="loading.jpg"
5a) Save your sys.txt.
6) Start Primo, you should see your new loading screen.
7) Exit Primo, you should see your new exiting screen.
If you don't see your new custom screens (either and both), you have done something wrong...review the steps.
If you are sure that you have followed the steps exactly, and you are still not seeing your custom loading/exit screens, you may be using some kind of customized data.zip and/or branding.zip that makes normal editing/operation more difficult or impossible.

PS. This method to get both loading and shutdown screens works only on Primo (2.0 definitely, 1.2 maybe). Primo can 'understand' the JPG extension and/or use *.jpg graphics files. Earlier versions of iGo software may not (and this method could result in a startup error/failure on iGo8 and others).
