I’m moving this from the comment thread from the Announcements post because I thought it deserved its own post.
Anonymous asked: Will independent developers be able to program iPod games and submit them to the iTunes Store for sale?
To the best of my googling, there is yet no public iPod software development package. The games are stored, by the way, in the iPod Games folder of your main iTunes folder. They have an .ipg extension.
These .ipg files are actually zipped up. Copy one over to a spare directory, rename it to foo.gz and then unzip it, e.g. unzip foo.gz. (Yeah, I tried gunzipping first but there were multiple entities.)
The actual executable is a “.bin” file. There are iTunesArtwork and iTunesMetaData files in there along with language locatizations, sound files, and a Manifest which lists the files and their sizes and a p7b Manifest that handles Fairplay.
