Hey, Master and Grand Master won't unlock for me. I have all the other offline achievements, and now I have over 10mil score, and I'm sure I've played over 200 games but still havn't unlocked those two.
Would not selecting a stats device cause the game to lose all the info when I exited game? I got all the other achievements in one sitting, took a break after getting Buku Bank. Would that be a reason they won't unlock?
*EDIT* k just got the achievements. You have to select a harddrive for both save game and stats. I forgot to press Y the first time through and the game didn't save any of my stats so I had to get 10,000,000 score and 200 games from scratch
