methods have been patched.
You still get it in customs with 1 controller - Load up Oddball, go to settings and set score to win as "30sec." Pick a map (I went 1-8 in order), start match, grab the ball, wait for the win and repeat 8 times (different maps)EDIT
: As stated by "Tarvu:" You can end the game when the match starts and it will count towards the achievement
, so winning the match is not needed. I did not test this, so I cannot 100% verify.
