As far as we know, Ben Sinclair is one of the first ever dissecting a .IPG (iPod game) file and reports us what he found.
So anyway, Nate downloaded the iPod Mini Golf game and let me take a look. The .IPG file is actually just a ZIP archive.
The archive contains many files, including AAC and WAV audio, XML, executables, language files, and more. I just started looking things over, but here are some of the interesting things I’ve found so far.
The iTunesMetaData file contains information such as the game title for use in iTunes itself.
If you modify the strings in there, you can rename the game.
iTunesArtwork is a JPEG file that is used for the game screenshot in iTunes.
Also used by iTunes is Description.xml and its associated images found in Resources/en (where en is your language). It tells iTunes how to display the help image.
