Now that Apple have stopped selling Click Wheel Games is there a repository for them?
I tried and failed to find a repository a while back, however if you're lucky, there are torrents for the complete archive which crop up sometimes. Obviously the torrents exist in multiple places, but there are rarely any seeders.

Obviously you'd have had to purchase them to be entitled to use them, and if you had purchased them, you wouldn't have been able to download them again as this was all before you were able to re-download purchased apps, so this may be an ideal solution to get things you'd lost and not backed up.
