Sure they can. Why not. They unlocked Battle vs A.I. which actually requires you to get at least bronze in every training mission.
Both titles are on the disc. There is no need to download them from somewhere else. Both titles are coded directly to the game itself. The game is doing nothing more than checking your profile and leaderboard as soon as your are conncected to the LP2 server. If you are placed between 1 and 10 in one of the standard leaderboards you get this nom. Those leaderboards are currently the only ones the script will accept 'cauz the basic string is the same and hasn't been affected via the patch or the DLC....otherwise it would simply unlock the nom.
It's super easy stuff I learned at school, lol. I can even code a PHP script you can load into your browser which requires you to type in a specific number to get access to my home server.
There are several ways to patch it:
- simply unlocking the nom (can cauze the most problems if you are not doing it right)
- change the value of the nom so it's still unlockable but no need for the achievement itself (no need to say that it can also cause lots of problems)
- add the DLC leaderboard to the list of possible options to unlock NUMBER 1 and TOP 10. So far there is, let's say for now, leaderboard 0 - 52. But unfortunately the new leaderboard is number 53 and simply will never count as a given requirement)
Sure, sounds all easy. And I know it's actually not that easy but also not hard on the other side. But Capcom is the one who made this game.
