Oh neat. That key extraction technique is very fun. Has anyone seen this this before in another major project?

Yes, the general flaw/technique is alarmingly common.

(Nintendo really ought to have known better, but I suppose the security of their alarm clock product isn't exactly a top priority - and given the hardware choice it was mostly out of their control anyway)

It is indeed a really cool key extraction method. The code is also written in such a straightforward way that it is easy to grasp what's going on.

Now I have to find some encrypted files to play with :D
