*bni

[Skywing]

I've written a program to view and edit .bni files.  You can grab it here.  The editor allows you to use any program which can save TGAs to modify the icon strip itself.  The BNI header itself is provided in a format similar to Visual C++ .RC files.  You should be able to save BNIs with 24-bit or 32-bit TGAs, and both the bottom-up and right-left ordering flags.

This might come in handy for testing your support for rarely used features (the editor also supports setting multiple product matches per icon).
