Windows Mobile : Which icon is the application icon?

I am trying to write a unix command line utility that will extract the "application" icon from a Windows Mobile executable. When I look inside the .exe with wrestool from the icoutils package, I see multiple icon and group_icon resources. I am trying to figure out which icon the Windows Mobile Programs view would choose to display to the end user.

At first, I figured it would be the icon with name 32512 (IDI_APPLICATION), but then I found several Windows Mobile binaries that lacked this icon resource, but sure enough had visible icons in the Programs view.

Is there a simple but correct algorithm? like lowest resource id? Is there another resource in the .exe that tells me what is the application icon? Is there something obvious that I am missing?

Any insight would be appreciated.

• It's the first RT_GROUP_ICON resource in the executable.
