Anyone ever play these games?  I've played 1 and 2 on MAME a few times, but can't seem to get to level 500.  For some reason TGM2 seems easier at first.  Maybe the control is better.  I'd like to reach level 999 sometime, even if I don't get the "GM" rank.  It's hard and like all Tetris games, it likes to give me useless pieces.  :P 

Anyone else play these?
