I'm not sure if this is the right thread, but could the savedongle be used to make an exploit? I know it sounds like a very n00by question, but...
Maybe.
(Im an optimist, unlike some people)
All the Save Dongle does is extract and insert save files, we've already tried editing save files which we found did not work. So the Save Dongle couldn't lead to any exploit or anything.
In all fairness modified save files did not work due to checksums. It's not a problem with the Save Dongle.
When someone figures out how the (last 6*?) checksums/hashes are made it will be possible to use the Save Dongle to test for save file-based exploits. Nothing "direct" will come from the Save Dongle but it could
enable users to search for exploits when the (again, last 6*?) checksums/hashes are found. I don't think we know
exactly if there are 6* checksums/hashes left to figure out what's being checksummed before save file modifying will work as there may be something missed thus far, but we do know there are at least 6* more checksums/hashes so far.
* = 5 hashes, 1 checksum
