Hopefully my token search before this thread did not miss something obvious. Anyway for those unaware the DSi and 3ds have a whitelist of all the old DS games released/compiled before a certain point in time. Games that are on this list (so all the licensed and sanctioned games) run, games that are not do not, unless you do something like http://hackmii.com/2010/02/lawsuit-coming-in-3-2-1/ . A few weeks ago I saw http://gbatemp.net/threads/release-use-blocked-ds-flashcards-on-3ds-probably-n3ds-too.376719/ but it turned out it was less hacking and more reverting to an older version. Still with the 3ds being looked at slightly harder than the DSi the 3ds might be a better place to start. I then wondered if anybody extracted the whitelist and got it into a parseable form. The obvious thing to do after that being to look for undumped games (either in general, for different regions or if they got a v1.1 version that was unknown beforehand). Presumably it would be a serial/header/hash affair rather than a dat but hopefully something that could be used.
