If you go to the library it tells you the answer its; 3, 1, 2, 4
I just downloaded the latest mobile version and it won't let me get past the title page. I get the start new game prompt and no A or B buttons. Tapping the screen seems to do nothing. I still get the directional buttons.
Edit: through thorough button mashing I found out that the game uses the up arrow as the select button, not tapping or an A button. Hope this helps others avoid the scams!
