Apparently you can cheat to unlock them by disconnecting your console from the internet, changing the date from the system menu, booting up the game and getting it to save (play a match or mess with menu options or something), then going back to the dashboard and changing the date again. Repeat until all titles are obtained.
I'm way too lazy for that, so I'll just get the titles legitimately though.
You don't have to disconnect the console for that. Just change the date, increase one day on the date time, then issue a save. You just have to do it 300 times.
Haha I thought the same thing with the internal clock but yeah unfortunately it keeps track of the days you play, not the days you've owned the game. Big thanks for posting the list though
