Well on the psp I know a couple.
1. hold down the L & R buttons plus O for your gather ( the player will do a cart-wheel) then push the O button again he will put it in between his legs twice ( let go after he goes through once) a 50 every time.
2. Hold down the L & R buttons plus the square button for your gather then push the O button he will go behind his back (If timed perfectly a 50 but I've never got less than a 48)
Hold L2 and R2 all the time, take off using 0 and then 0 again, hanspring under the legs twice, 50 on its own or you can do it alley-oop style just for the hell
also alley-oop off the backboard, x then triangle (L2 and R2 for both) slam it and hang from your elbow, another 50
there is no DC (dunk contest) on the 2k9 for the ps2
They have NBA Live games, which have slam dunk contests.
USe Allen iverson
yes it does
No
There was no NBA Slam Dunk contest in 1998 Due to a lockout.
Yes he won the 2011 slam dunk contest
No, he will not compete in the Slam Dunk Contest.
On the dunk contest just keep practicing doing alleys and dunking or a really good dunk through the slam dunk school. Unique and harder executing dunks score better and have a higher chance of scoring a 50.
No
