Find the line: skin_name="your_skin_filename_here".
Cause: The data.zip does not recognize the skin folder structure.
Fix: Open your data.zip with 7-Zip. Navigate to ui_igo9. Create a folder inside named 800_480. Inside that, create a folder named ui. Then copy a blank text file and rename it to skin.skin. Save the data.zip (store, not compress).
The following steps outline the standard installation for a WinCE 800x480 device: skin igo primo 24 wince 800x480 work
Step 1: Data Backup
Copy the entire contents of the internal memory or SD card to a PC. This preserves the original sys.txt and license files.
Step 2: File Transfer
Download the Gj 24 skin (usually packaged as a .zip file). Do not unzip the skin file itself. Place the .zip file into the directory:
[iGO Root]/content/skin/ Find the line: skin_name="your_skin_filename_here"
Step 3: Configuration (sys.txt)
The sys.txt file located in the root folder governs the software's behavior. For the 800x480 resolution, the screen configuration must be explicitly set if auto-detection fails. Add or verify the following lines:
[interface]
skin="ui_igo9"
resolution_dir="800_480"
screen_x=800
screen_y=480
[rawdisplay]
screen_x=800
screen_y=480
class="landscape"
highres=0
