ISO Info: NBA2K13 ALL STAR UNLOCKED & hidden ARENA UNLOCKED

Can anyone explain to me what it is/does??

Here is the download link: NBA2K13 ALL STAR UNLOCKED & hidden ARENA UNLOCKED TRAINER!!

Nobody??

well, looking at it, it seems to let you use the all star teams in play now and play in special arenas that you choose.

well its actually a pretty cool tool! very useful and comfortable..
if u wanted to do shootarounds and drills at a normal broadcast camera, now you can!
if u wanted to practice your myplayer skills at the streets, now its possible too!
if u wanted to play the eastern allstars against the 97 bulls on the training camps gym, no its possible also!
and much more

here's couple of pictures
