go to blockbuster.
the game rental cover-boxes (the ones with the artwork) have the dna codes in them. i discovered this today and was able to hoard 3 of them. why you might ask?
to be able to play more than one dynamic season.
apparently you can only have one dynamic season per storage device, be it hard drive or memory card. i have one of each so i can run two seasons that way.... however, there is another way... and now i have 8 dynamic seasons running on one xbox 360.
one file for each team
CAVS
MAGIC
CELTICS
HEAT
LAKERS
MAVS
SUNS
NUGGETS
how?
first off i have 2 storage devices, and 4 user profiles on my x360, all with the free silver account.
if you have more than one xbox live profile on your system, only the profile you had active when you redeemed your code may use the dynamic dna feature. however, if you can score more dna codes, at the aforementioned location... then you can load up the code onto another profile connected to at least xbox live silver and from there, save a new dynamic season on that profile with the same hard drive/memory card as your previous saves.
the main reason i wanted to do this is so i could take multiple teams and rewrite history this season... but not all at the same time, and with minimal impact to the overall records/stats of the other teams in the league. controlling 6 teams at a time... you end up with a very different nba season. controlling one team at a time, you only effect the outcome of that teams games... and a slight impact on whoever you played against, more so if they are in your division, less if they are in the other conference.
on to blockbuster, make haste!
